My base assumption is that each season is roughly a calendar year.
All timing below is based on that. (See FAQ for details.)
We're given almost no specific dates or times, so much of what's here is a guess.
I assume that aired canon happens chronologically unless we're told otherwise.
THIS IS NOT YET COMPLETE!
Several seasons have incomplete information. I'll get to them as I have
time. I'm putting this up even in its incomplete form because I figure a partial timeline
is better than nothing.
Break out of the frame | Updated April 12, 2006 | Get the frame back
Ancient History | 0001-1899 | 1900-1994 | 1995-1996 |
1997 | 1998 | 1999 | 2000 | 2001 | 2002 | 2003 | 2004 | 2005
Lines between entries are a basic 'time passes' indicator, for situations
where I don't know how much time has passed between events,
usually in different episodes.
nb: In late eighth season, prop canon appeared suggesting that the end of first season happened in August 1997, rather than later in that year. I ignore that (see FAQ for details on why).
If you believe that the date on the calendar is correct, basically this entire timeline will be wrong for you in specifics, and only good for a general sense of the universe's overall chronology.
5-10 million years ago | Several million years ago | 'Ages ago' | ca. 100,000 BC | ca. 28,000 BC | ca. 13,000 BC | ca. 9,000 BC | ca. 8,000 BC | ca. 3,000 BC | ca. 2,000 BC | ca. 1,000 BC | ca. 900 BC
After a journey of possibly thousands of years, the Altera (Ancients) discover a 'great belt of stars' and make their home on a world they call Avalon (Earth), and begin building astria porta (stargates). (Avalon part 2)
The Ancients live on Earth, based in the city of Atlantis on the Antarctic continent. (SGA: Rising pt 1)
The Ancients in the Milky Way are struck by a virulent plague that starts to wipe out the race. (Full Circle, SGA: Rising pt 1)
The Ancients leave Earth, flying off in the city of Atlantis, headed for the Pegasus galaxy. (SGA: Rising pt 1)
Millions of years ago (3-50 million), Ayiana, who was possibly/probably an Ancient, was put into cyrogenic stasis and somehow wound up in the Antarctic. (Frozen)
This is most likely to have happened when the Ancients flew off in Atlantis, but there is no specific, spoken canon to support that.
Ages ago, built up over several millennia, there was an alliance of four races: the Ancients, the Asgard, the Furlings, and the Nox.
The Ancients supposedly moved on long ago, leaving behind their technology, knowledge, and allies. In fact, they were overcome by plague -- most died, but some of them ascended to a higher plane and became known as Ascendants, although for the most part they didn't interfere with other races.
The Asgard have remained active participants in galactic (and inter-galactic) affairs, interacting with younger races.
The Furlings seem to have vanished leaving only one trace, on Ernest's planet. That trace evidence has since fallen into a sea and vanished as well.
The Nox remain, but have withdrawn from galactic affairs for the most part.
A plural-minded organism (almost bacteria-like) that lives on P5C-353 creates an orb and retreated to it when its/their world is dying. They lay dormant for 100,000 years. (Message in a Bottle)
A ship is launched from the Asgard homeworld, its crew in suspended animation. The Asgard also embark on (or possibly continue) a plan of genetic manipulation, changing their form. (Revelations)
A likely alien gate terminal on Hadante is set up. (Prisoners)
Altair's biosphere begins to fail, and a man named Hubald creates an underground complex for the survivors of his race. About a thousand people transfer their consciousnesses to synthetic bodies, to allow the ract to survive in at least some fashion. (Tin Man)
Myrddin is among the Ancients who flee Atlantis and return to Earth. (Avalon part 1)
Ra arrives on Earth and takes a human host. (Stargate, the movie)
The Goa'uld who controls the planet where Kelowna, Andaria, and Tirania eventually emerged attempts some experiments with creating naquadria bombs, and nearly destroys the planet. (Meridian)
Ra is still on Earth. (Moebius part 1)
SG-1 travels back in time to roughly 3,000 BC to try to find and take a ZPM in Ra's possession before he leaves the planet with it. They gain access to Ra's temple in a public audience, then slip further in, taking out a Horus guard to steal his armor. Teal'c disguises himself as the Horus guard (complete with retracting helmet) and steals the ZPM. Unable to return to the jumper, SG-1 plants the ZPM and a camcorder with recordings from all of them detailing what happened and why in a First Dynasty tomb that Daniel knows will be dug up shortly before they leave in the future. (Moebius part 1)
SG-1 is trapped on Earth in the past. They decide to jumpstart the rebellion, but during the process, Jack, Sam, and Teal'c are captured and executed. Daniel survives and works with a man named Kapet to continue planning the rebellion, more slowly and carefully this time. (Moebius part 2)
The alternate-timeline Jack, Sam, and Teal'c arrive in ancient Egypt to keep Ra from leaving with the stargate, and to help with the uprising. No record of their existence or action survives into the future -- only the actions of the original-timeline team, on the camcorder. (Moebius part 2)
The uprising against Ra succeeds, and the stargate is successfully stolen and buried where it can be found later by Dr. Langford. (Moebius part 2)
Omoroca comes to Earth to try to free its people from Goa'uld tyranny. The Goa'uld Belus kills her. (Fire and Water)
Thanos is still living on Jonas's world. He creates naquadria in the lab, but something goes wrong and it explodes, killing him and releasing sub-atomic particles that catalyze a nearby naquadah deposit, which turns into naquadria. (Fallout)
nb: This is a timeline glitch, since originally Thanos is supposed to have nearly destroyed the world with that explosion around 8,000 BC, according to both Daniel and Jonas in Meridian
Early Mayan tribes are using a piece of alien technology to serve as a Fountain of Youth. It's connected with Chac, the Mayan rain god (who may also be the Goa'uld Telchak). (Evolution, part 1)
ca. 0001 | ca 100 | ca. 400-500 | 750 | 976 | ca. 1000 | ca. 1249 | ca. 1300 | ca. 1399 | ca. 1440 | ca. 1549 | 1565 | ca. 1600 | ca. 1699 | ca. 1700 | ca. 1795 | ca. 1800 | early 1800s | ca. mid-1800s | ca. 1849-50 | 1864 | late 1800s
The stargate at Giza is buried. (Frozen)
(Personal note: This is beyond absurd. We have extensive written records from the period, and people would have jotted down a note or two about hordes of godlike alien enslavers being thrown off the planet en masse by a widespread uprising of the downtrodden. Really. The original explanation of this happening ten thousand years ago makes much more sense.)
Hathor is imprisoned (by an unknown person or persons) in a sarcophagus that is later found in a Mayan temple (no idea whether she starts out in the temple, or if the sarcophagus is moved there). (Hathor)
The Bedrosian and Optrican world undergo a period of severe earthquakes and volcanic eruptions, later known as the Upheaval, which buries their stargate and DHD. (New Ground)
Egeria spawns the Tok'ra. (Upgrades) She is then assumed killed on Earth (by Ra), but is in fact imprisoned on the planet Pangara. (Cure)
The Goa'uld abandon Kelowna completely -- the ring platform falls into disuse. (Homecoming)
The planet Madrona is terraformed [sic] by an unknown race. (Touchstone)
Myrddin sets up a test for the Knights of the Round Table in a series of hidden chambers under Glastonbury Tor, designed to test their worthiness to be given the riches of Ambrosius Aurelianus (possibly King Arthur). (Avalon part 1)
Teotihuacan suffers a great upheaval and its civiliation disappears, possibly as a result of Goa'uld incursion. (Learning Curve)
A chemical disaster nearly destroys P7J-989, and the few survivors place their bodies into suspended animation, in the care of a Keeper, to keep the race alive until the planet can restore itself. (Gamekeeper)
Anubis is banished from the System Lords 'forever' -- they even attempt to murder him, and think they've succeeded. (Last Stand)
Thor creates Cimmeria as a safe world for some Norse people he rescued from Earth. (The year is a guess -- it happened an Asgard 'ten-span' ago.) (Thor's Chariot)
A village of Christians from England is taken by Sokar, possibly through the Antarctic gate, and put on a world where he convinces them he's actually Satan. (Demons)
Goa'uld arrive on the Crystal Unity's world, and one touches a crystal. The energy in the crystal kills him, and in retaliation, the Goa'uld gather up all the Unity (crystals) and put them in a pit, then shoot them with staff weapons, shattering almost all of them. (Cold Lazarus)
The inhabitants of PXY-887 defeat the Goa'uld on their world, and take on the names/guise of the 'spirits' of the human Salish tribe that the Goa'uld brought there, to allow the two races to live in harmony. (Spirits)
A Goa'uld in the body of an Unas is trapped in the caves that make up 'Thor's Hammer', where he lives for the next thousand or so years. (Thor's Hammer)
The Asgard lose the ability to sexually reproduce: every Asgard alive from this point forward has been alive since at least this time, using a succession of cloned bodies to survive. (Revelations)
Meteor strikes hammer Edora. (A Hundred Days)
Pyrus ('the godslayer') is born on P3R-636. (Need)
Meteor strikes hammer Edora. (A Hundred Days)

The surviving people of P3X-289 build an energy dome complete with computerized systems maintenance, to give their race someplace to survive on the now-toxic surface of their world. (Revisions)
Meteor strikes hammer Edora. (A Hundred Days)
Apophis defeats the System Lord Shak'ran. (Cure)
The Latonans build the Sentinel as a defense system for their entire planet. (The Sentinel)
Written Tagrean history begins as Tagrea emerges from its dark age. (Memento)
Saroosh is born. (Tok'ra, part 1)
The geothermal vents powering the dome on P3X-289 begin to cool, reducing its source of energy and causing it to start to contract. (Revisions)
Napoleon takes Sekhmet artifacts, probably out of an Egyptian tomb or crypt. (Resurrection)
nb: No date is actually given, but this, give or take a couple of years, is the most likely -- Daniel says the artifacts likely came from an Egyptian tomb or crypt, Sam says they go back to Napoleon, and Napoleon [or at least his troops] was in Egypt from 1798 to 1801.
An unnamed Ancient abandons a time machine on a world whose history he or she had been studying. (It's Good to Be King)
Seth sets up a cult in England, near Stonehenge. (Seth)

1899/1900 | ca. 1900 | early 1920s | 1924 | 1928 | ca. 1940-1944 | ca. 1942 | 1945 | late 1940s | mid-20th century | ca. 1950 | mid- to late 1900s | 1957 | ca. 1962 | 1964/1965 | ca. 1968 | 1969 | late 1960s to early 1970s | ca. 1970 | 1971 | 1973 | ca. 1973 | mid- to late 1970s | 1980 | 1982 | 1984 | 1985 | ca. 1985 | 1986 | ca. 1988 | 1985-1990 | 1985-1995 | 1990-1991 | 1991 | 1992/1993 | 1993 | 1994
Teal'c is born. (The Light)
Bra'tac is First Prime to Apophis. (Into the Fire)
Baal gives up ownership/control of P4S-237 (where Ellori's people live). Mot, an under-System Lord, sets himself up as Baal's emissary without telling Baal, taking the mined naquadah for himself. (Prophecy)
The Pangarans discover a Goa'uld temple on their world, and begin digging to find more. (Cure)
A 'stone' (actually looks like metal with crystal inserts, in an elongated, rounded shape) -- is discovered in an Egyptian tomb wrapped in a scroll with writing on it no one could read. (Paradise Lost)
Catherine Langford is born. (Torment of Tantalus)
Dr. Langford discovers a stargate at a dig at Giza. (1969)
President Roosevelt orders tests done on the stargate 'during the war' to see if it could be used as a weapon. The experiments are headed by Professor Langford, Catherine's father. (Torment of Tantalus)
Nazis recover Sekhmet artifacts originally found by Napoleon. (Resurrection)
nb: The date is an assumption on my part, but I think it's a completely reasonable one. Sam said the Nazis recovered the artifacts, and 1940-1944 was the Nazi occupation of Paris.
The Pangarans find Egeria, who has been imprisoned on their world for two millennia, and begin performing medical experiments on her. (Cure)
The first Loop of Kon Garat is flown in the Hebridan system. (Space Race)
nb: This date could be off by several years in either direction, depending on how long a Hebridan year is. In 2003, the 59th Loop is raced. (Space Race)
January
The stargate is activated for the first time in some 2,000 years when Dr. Ernest Littlefield goes through to a destination later designated as P3X-972. (Torment of Tantalus)
After Ernest vanishes through the wormhole, the program is shut down. (Torment of Tantalus)
The gate is crated and sent to an armory, where the military could deny its existence. (Torment of Tantalus)
The Russian military takes a DHD away from the Germans, who had found it at Giza. They study it even without a gate to attach it to. (Watergate)
Nicholas Ballard spends decades searching South America for the piece of alien technology he's convinced forms the basis of the Fountain of Youth. (Evolution, part 1)
The Pangarans begin performing medical experiments on Egeria. (Cure)

Bedrosia and Optrica engage in a decades-long religious war. (New Ground)
Jack O'Neill is born. (Brief Candle)
Alec Colson is born. (Covenant)
July 8
Daniel Jackson is born. (I believe 1965 to be more likely, but 1964 is possible.) (1969, Forever in a Day)

August 4-10
SG-1 travels cross-country in a bus with Michael and Jenny, along Route 66. Michael and Jenny are going to Woodstock. (1969)
August 10
SG-1 makes it to the East Coast. Daniel and Sam go to talk to Catherine in New York (in disguise, more or less -- Daniel as a German whose father supposedly worked with Catherine's father), to ask her what she knows about the gate's current whereabouts. Jack and Teal'c go to an observatory to test Sam's theory that they're looking for a solar flare. (1969)
August 11
Michael and Jenny drop SG-1 off in Washington, where they go to the warehouse where the stargate is stored, and hook it up to a bunch of truck engines to open a wormhole to send them back to their own time at 6:03pm ET, when the solar flare strikes. (1969)
Hammond and Henry Hayes know each other as lieutenants. (Lost City, part 1)
nb: The time is a guess on my part, but with Hammond canonically a lieutenant in 1969, it seems reasonable.
The Pangarans begin using Egeria to breed symbiotes that they then use to create tretonin, a medicine that renders them impervious to all ailments. Egeria deliberately produces offspring with no genetic knowledge at all. This lasts for some 30 years. (Cure)
Nick Ballard discovers a crystal skull in a ruined temple in Belize (possibly while searching for the Fountain of Youth? -- Evolution, part 1), which transpors him to an alien world where he finds 'giant aliens' who rise up like mist to greet him. When he is transported back to the temple, it collapses around him, and he barely escapes. (Crystal Skull)
Daniel's parents die when a slab of heavy rock they're placing in an exhibit in the New York Museum of Art falls, crushing them. (Gamekeeper)
The Goa'uld Moloc decrees that only male children of Jaffa would be allowed to live -- all female children must be put to death. (Birthright)
Nick Ballard checks himself into a psychiatric institute, having convinced himself that his trip to another world was a hallucination. He remains there for about 20 years. (Crystal Skull)
Work begins, using three supercomputers, on trying to figure out how to open the stargate. (Children of the Gods) The original research team had to create an interface between the computer and the stargate. They did this by generating a series of instructions based on electrical impulses to which the gate's control crystals would respond. They found these by trial and error -- thus the fifteen years. (48 Hours)
Jack O'Neill is a captain in the Air Force. He is part of Operation East Fly, a mission to retrieve a Russian agent named Boris from a house in East Germany. The team also includes Captain Kawalsky, under the command of Colonel John Michaels, who is killed in action by snipers. (Gamekeeper)
Loki is stripped of his stature [sic] after being discovered performing unsanctioned experiments on humans on Earth. His experiments stop. (Fragile Balance)

Alec Colson's wife and daughter die in a plane crash, and he starts Colson Aviation in hopes of making flying safer for everyone. (Covenant)
Merrin of Orban is born. (Learning Curve)
nb: The year is a guess -- in 1999, she said she was 11 years old, but there's no clear indication how long an Orbanian year is.
Tomin of Orban is born. (Learning Curve)
nb: The year is a guess -- in 1999, his father said it would be another six months before Tomin turned 12, so this could be 1987 as easily. Also, there's no clear indication how long an Orbanian year is.
Teal'c is made First Prime to Apophis.
There's no canonical evidence at all of when exactly this happens, but he'd been First Prime for a while before he met SG-1, and he wasn't yet First Prime when Drey'auc was pregnant with Rya'c, who has to have been born within a year or two of 1985. (Threshold)
It's highly unlikely to be any later than 1990, and is probably several years earlier -- he was First Prime when he killed Hanno's father during Hanno's childhood (he was roughly ten years old), and Hanno was a full-grown adult in 1997 (he appeared to be in his early 20s), when he accused Teal'c of the crime. (Cor-Ai)
So, at a rough guess, 1986 or 1987 are the most likely years for him to have become First Prime.
On Apophis's orders, Teal'c kills one of the Byrsa to teach them all a lesson. He chooses young Hanno's father, knowing that he's too lame to run quickly, and thus slows down everyone else when they flee the Jaffa. (Cor-Ai)
Jack O'Neill's duties are classified. (Children of the Gods)
Sam clocks more than 100 hours in enemy airspace during the Gulf War. (Children of the Gods)
January 16 - March 20
Jack O'Neill serves in the Gulf War with Harlan Beck, in Operation Proven Force out of Incirlik. (Jack possibly runs a part of the operation, but he never quite says so explicitly.) He is possibly already a colonel at this point, or a lieutenant colonel. (Fragile Balance)
(http://www.fas.org/man/dod-101/ops/proven_force.htm)
After years of trying, Catherine Langford finally succeeds in petitioning the administration to reopen the project. The Stargate Project officially starts up as a secret project under Pentagon control, as they try to unlock the gate's secrets, under the command of General West. Some research is being done at Cheyenne Mountain with the gate itself, other research is being done at the Pentagon. Captain Samantha Carter is part of the Pentagon team. (Children of the Gods)
Hammond's wife dies of cancer. (Tin Man)
The Tok'ra incite an uprising on Vala's homeworld against the ruling Goa'uld -- which happens to be the symbiote Vala is infested with. She is captured alive, tortured, and beaten for days on end,. (Prometheus Unbound)
The Tok'ra responsible for the uprising rescues Vala, removes the symbiote from her, and nurses her back to health. (Prometheus Unbound)
A short time after the uprising against Vala's Goa'uld symbiote, Camulus arrives on her world and claims it as his own. The Tok're who'd inspired the original uprising vanishes. When the people refuse to surrender, Camulus orders them wiped out. (Prometheus Unbound)
Note: I know the movie was 1994. This is fudging to make it fit with show canon, where Daniel -- who was recovered in early 1997 -- had been on Abydos for 'over a year', but not two years. That puts the first Abydos mission in late 1995. Best I can do.
Daniel stops visiting his grandfather, Nick Ballard, in the psychiatric institution, when they have a falling out over Daniel's 'insane' theories. (Crystal Skull)
Charlie O'Neill dies by accidentally shooting himself with Jack's gun. (Stargate the movie, Children of the Gods)
nb: The year is never actually given, but the implication is that it's no more than a few months before the stargate program starts up.
Jack retires from active duty. (Stargate the movie, Children of the Gods)
nb: The year is never actually given, but the implication is that it's no more than a few months before the stargate program starts up.

Ra's troops then attack the Abydonians in retribution for helping the interlopers. The Abydonian youth rise up in protest, with Sha're's help/guidance, and manage to stage an escape for the prisoners. They combine forces, and attack Ra's temple. (Stargate, the movie)
Eventually, Jack and Daniel manage to ring an activated nuclear warhead up onto Ra's ha'tak as it flees the planet, destroying it and Ra. (Stargate, the movie)
Jack, Kawalsky, and Ferretti return home and report that Daniel is dead, as are the Abydonians and Ra, and that the Abydonian stargate was destroyed behind them. (Children of the Gods)
Daniel stays behind, marries Sha're, and organizes a local militia among the boys. After the report that Abydos was destroyed, the gate is covered with a tarp and the program is largely scrapped. (Stargate, the movie)
Jack retires from active duty again. (Children of the Gods)

Late January/ early February
General George Hammond is one month away from retirement. (Children of the Gods)
The program is in the final stages of shutdown when Apophis comes through the gate, killing several SFs and taking one sergeant (female) back with him through the gate, effectively starting the program back up again. (Children of the Gods)
Early February
Colonel Jack O'Neill (Ret.) is brought to Cheyenne Mountain and admits to having lied about killing the Abydonians and Dr. Daniel Jackson's death. He's reactivated so he can lead a team through the stargate to find out if the alien intruder had come from Abydos.(Children of the Gods)

Drey'auc and Rya'c are outcast after Teal'c's betrayal, forced to leave their home and live in the camps outside the city.) (Bloodlines)
February 10-11
Nine teams are approved, whose original (and continuing main) duties are to perform reconnassaince, determine threats, and if possible make contact with the peoples of the worlds they go to. The teams were to operate on a covert, top-secret basis, with only the Joint Chiefs and the president knowing of their existence. The initial briefing after Daniel was brought back from Aybdos was classified S.C.I. Top Secret. (Children of the Gods)
The stargate is covered with a retractable iris made of titanium, to prevent unwanted intruders. (Children of the Gods)

A presidential directive is issued to evaluate the scientific and cultural value of each mission -- ensuring that the SGC will never be a purely military operation. (Broca Divide)
March 10
Date of Hammond's official report about the 'Touched' virus that had infected the entire SGC. (Politics)
SG-9 travels to P3X-513, where the team spends several weeks getting to know the locals. (First Commandment)
Four-five weeks into the mission, Captain Jonas Hanson, the team leader, spends two full days out under the brutal sun looking for a lost child, and goes insane.

After Merrin's Avarium, the Orbanians begin trying to teach post-Avarium children 'the old-fashioned way'. (Learning Curve)
Roughly a year after Daniel discovers an alternate reality by using the quantum mirror, two members of another alternate reality -- Dr. Samantha Carter and Major Charles Kawalsky -- appear at Area 51 after using the mirror on their own world. Their world was invaded the day before by Apophis, and was rapidly being conquered. They are interrogated at Nellis AFB. (Point of View)
Two days after being interrogated, they've explained their story to the SGC as well, and have been granted permission to stay. (Point of View)
Jack learns that his AR-self was married to the AR-Carter. (Point of View)
Dr. Carter and Major Carter, working together, manage to get the Asgard power-booster working again (thanks in part to Sam's work on the naquadah reactor in Learning Curve). (Point of View)
Jack, Daniel, Teal'c, Dr. Carter, and Major Kawalsky travel to the alternate reality to ask the Asgard of that reality for help fighting the Goa'uld invasion. (Point of View)
Teal'c kills his alternate self after one brief (and refused) offer to spare him if he renounced Apophis. (Point of View)
The AR-Earth is rescued by the Asgard. (Point of View)
The quantum mirror on 'our' Earth is possibly destroyed, but that's never confirmed. (Point of View)
Korra of the Tok'ra steals a cargo ship from Sokar and flees, believing he has been discovered as a spy. (Deadman Switch)

Teal'c sees a Goa'uld cloaking device (on a cargo ship) for the first time. (Deadman Switch)
Word of Sam's being blended with Jolinar has spread far enough that a bounty hunter like Aris Boch knows about it. (Deadman Switch)
SG-1 learns that Aris Boch's race can't be used as hosts by the Goa'uld. (Deadman Switch)
SG-1 agrees to help Aris Boch capture a Goa'uld, but discover he was lying -- it's really the Tok'ra Korra. They switch to helping him instead. (Deadman Switch)
Aris Boch recaptures everyone, including Korra. Teal'c offers himself in exchange for Korra, for Aris to trade to Sokar, to protect the other Tok'ra in Sokar's ranks from discovery. (Deadman Switch)
Aris Boch has a change of heart, and stages a ship explosion as he and Teal'c are on the way to meet Sokar's ship -- they escape in pods. (Deadman Switch)
Aris Boch gives Sam a vial of roshna to run tests on, in hopes that some day his people can be freed of dependence on it (and thus enslavement to the Goa'uld). (Deadman Switch)
An SG unit (SG-1) makes contact with offworld Christians for the first time. (Demons)
Jack and Teal'c spot their second Unas -- Daniel and Sam see one for the first time. This one is also Goa'ulded, likely one of the last, if not the last, in the galaxy. (Demons)
The entire team is accused of being unclean for traveling through the stargate, but Teal'c in particular is accused of being a witch, and is put to the Tests (Mark of the Devil and Water Test). The first gives proof of his unclean soul (he can't feel a red-hot poker against his Jaffa tattoo). The second appears to kill him, proving that he wasn't evil after all. (Demons)
SG-1 learns that a symbiote can keep a Jaffa from drowning (at least, if the Jaffa is in a deep state of kelno'reem before he hits the water) by filtering oxygen out of the water and feeding it into the Jaffa's bloodstream. (Demons)
The entire team, along with Mary (a local woman) is chained up as a sacrifice to Sokar. (Demons)
The villager Simon defies his spiritual leader (the canon) to help SG-1 and the villager Mary escape the Unas who's taking them all to Sokar. (Demons)
The Goa'uld inside the Unas host abandons the dying body, and enters the canon, where it does a good job of disguising itself at first. (Demons)
Sam senses that the canon is Goa'ulded -- Teal'c doesn't. (Demons)
Jack shoots and kills the Goa'ulded canon. (Demons)
Simon and Mary (and presumably the rest of the village) bury the stargate, and stop the sacrifices. (Demons)
Eight months after SG-11 is declared MIA on P89-534, SG-1 encounters a group of boys training to infiltrate the SGC. (Rules of Engagement)
SG-1 is 'killed' by intar weapons when they join a war game thinking it's a real battle. When they wake up, Teal'c masquerades as a Jaffa master come to test the boys, in order to gain information (and SG-1's freedom).(Rules of Engagement)
The weapons taken from SG-1 when they 'died' are the cause of an escalation in the war games, when Teal'c's staff weapon draws first blood, and triggers the final challenge. (Rules of Engagement)
After seeing a tape of Apophis's death at the SGC, Captain Kyle Rogers joins forces with SG-1 to stop the final challenge from occurring, and killing many of his men. (Rules of Engagement)
Rogers tells Hammond and SG-1 that SG-11 were killed after being captured and interrogated. (Rules of Engagement)
After they see the tape of Apophis's death, the boys all give up the final challenge. (Rules of Engagement)

Kasuf gets word to the SGC about the abduction before he himself is taken. (Forever in a Day)
Amaunet sends the harsesis child to safety on Kheb, sure no one will think to look for him there. (Forever in a Day, Maternal Instinct)
In battle with Amaunet's (Horus-guard) Jaffa, Sam very accurately uses a handheld rocket launcher. (Forever in a Day)
Amaunet ribbons Daniel nearly to death. (Forever in a Day)
Daniel has a multi-stage hallucination (in the time it takes a gun to start falling from his fingers and then hit the floor) that brings him to a point where he can forgive Teal'c for killing Sha're, and begin to focus on adjusting his search for Sha're to a search for the harsesis child. (Forever in a Day)
Teal'c shoots Amaunet with his staff weapon, saving Daniel's life but killing her (and Sha're). (Forever in a Day)
Roughly a year after the Vorlix struck Vyus, SG-1 visits the planet. (Past and Present)
Daniel meets Ke'ra and starts to fall (hard) for her (and vice versa). (Past and Present)
Fraiser discovers that the Vyans' memories exist, but that they're physically blocked by a residue in their synapses, and with Ke'ra's help works to find a cure. (Past and Present)
Sam's discovery that the Vorlix was likely the result of Linea's Dargol experiments, and that it caused age regression, raises the possibility that Linea isn't dead, but is instead Ke'ra (with her innate medical and chemical skills). It's confirmed by DNA testing, and Ke'ra (unaware of the truth) is confined to her quarters briefly. Sam and Janet convince Hammond and Jack to allow Ke'ra to continue helping them come up with a cure, since they can't do it themselves with the necessary speed to save Vyus from catastrophe. She figures out that everyone thinks she's Linea.(Past and Present)
Ke'ra, working with the others, comes up with a successful antidote to the memory blocks. (Past and Present)
Ke'ra, not believing that she's Linea, takes the antidote, and becomes a mix of Linea and Ke'ra -- Ke'ra on the surface, but Linea not buried very far. Knowing that she harbors a homicidal monster, she steals chemicals that will allow her to create a poisonous gas in her quarters, intending to commit suicide. (Past and Present)
Daniel talks Ke'ra/Linea into burying her memory again, to start fresh. She helps to synthesize a small amount of the enhanced Dargol and reintroduce it into her bloodstream. She loses her entire memory, and returns to Vyus as a blank-slate Ke'ra. (Past and Present)
Jacob is captured by Sokar on Delmak, and sentenced to torture and imprisonment on Netu. (Jolinar's Memories)
Martouf recruits SG-1, particularly Sam, to help retrieve Jacob from Netu -- and more importantly, the information he's gathered about Sokar's plans for conquest of other System Lords. Sam's buried memories of how Jolinar managed to escape from Netu are their only chance of escaping themselves. (Jolinar's Memories)
Four days after Jacob's capture, SG-1 and Martouf find him in 'the pit' on Netu, tortured nearly to death. (Jolinar's Memories)
Bynarr, Lord of Netu, is killed seconds before he ribbons Sam, shot in the back by his First Prime, Na'onak. (Jolinar's Memories)
SG-1, Martouf, and Jacob are captured seconds before they can ring out of Bynarr's quarters to safety. (Jolinar's Memories)
Na'onak takes over Netu, and reclaims his real name of Apophis. (Jolinar's Memories)
Roughly two days after SG-1 arrives to rescue Jacob, Sokar's fleet is ready to take on the System Lords (ahead of schedule). Sokar starts his trip by traveling to Netu to cleanse the underworld, since Bynarr is well overdue to report back about the intruders. (The Devil You Know)
Aldwin launches a weapon at Netu designed to explode its core. Apophis begins a coup attempt by gaining an audience with Sokar, but winds up being tortured. Word that Netu is about to explode causes a distraction that lets Apophis make a run for it. (The Devil You Know)
Apophis rings out to Delmak. (The Devil You Know)
Jack, Daniel, Sam, Jacob, and Martouf ring off Netu, and are intercepted by Teal'c in the cargo ship. The cargo ship flees. (The Devil You Know)

Apophis begins his takeover of Sokar's domain. (The Devil You Know)
Aliens begin a takeover of the SGC, using a device that allows them to perfectly duplicate anyone (down to mental processes, if the person is left alive). (Foothold)
Sam contacts Maybourne for help. Maybourne also gets a call from the fake Hammond and decides to believe him instead. Along with the fake Jack and Daniel, he flies with Sam back to the SGC so she can receive 'medical treatment' for her delusions. Sam kills the fake Jack and fake Major Davis aboard the plane and figures out what's going on, and how to interfere with the illusion's signal to make the aliens visible. She and Maybourne come up with a plan to rescue the SGC. (Foothold)
The aliens begin an evacuation -- at least a dozen escape, complete with detailed knowledge about the SGC and Earth in general. (Foothold)
Because of the seriousness of the security breach, all official records are purged of all information about it by presidential order. (Smoke and Mirrors)
The Tollans destroy two of Heru'ur's motherships, which were above their planet while chasing Klorel. (Pretense)
While fleeing from one of Heru'ur's battle groups, Klorel's death glider is damaged and he crash-lands on Tollana. Skaara is the one who wakes up, and begs for help from the Tollans who find the ship. The Tollans begin preparations for triad, to determine who has control of the body. (Pretense)
Two days after Skaara's ship crashes on Tollana, SG-1 are brought to Tollana and filled in on what's going on. Skaara chooses Jack and Daniel to be his archons. Klorel chooses (or is assigned) Zipacna. (Pretense)
The triad is decided in Skaara's favor. Zipacna calls in his mothership and tells it to attack -- it takes out almost all of Tollana's ion cannons. Teal'c and Lya bring the rest of SG-1 to the cannon Lya hid (at Teal'c's request), and Teal'c gets it working: it destroys the mothership. Zipacna escapes through the stargate. (Pretense)
Klorel is safely removed from Skaara and sent to an unnamed Goa'uld world. Skaara is free (and presumably goes to Abydos, although there's no evidence of that before Full Circle). (Pretense)
SG-1 travels through the gate to P4X-884, an apparently tropical world. (Urgo)
Fifteen hours later, they return, with absolutely no memory of the intervening time (Jack is finishing a sentence he started before he stepped through the gate). They discover that they've been implanted with a cybernetic life form -- Urgo. (Urgo)
All members of SG-1 are relieved of active duty when Sam's attempt to nullify Urgo fails. (Urgo)
The SGC contacts Togar, Urgo's creator, and he agrees to remove Urgo. He later agrees to implant Urgo in his own mind, to keep from killing him. (Urgo)
SG-1 return home more than ten hours after they left, with no idea what happened in the interim. (Urgo)
SG-1 visits Edora and befriends Laira and her family. (A Hundred Days)
Several days after first arriving on Edora, SG-1 experiences the 'fire rain' for the first time, realizing the meteors are far too large and close for comfort. They begin an evacuation of the local population for fear of catastrophe, but before they can get everyone out, a meteor hits the stargate. Jack is trapped on the planet with Laira and her family, and a few other survivors. (A Hundred Days)
24 hours after Edora's stargate is struck by a meteor, the SGC attempts to send a MALP through, to be followed by a rescue team. The wormhole engages, but the MALP is destroyed as soon as it reaches the other side. Hammond scrubs the rescue mission. (A Hundred Days)
The meteor strikes last for at least three days, possibly more. After three days, the surviving villagers try to escape through the stargate, only to find it buried. (A Hundred Days)
Several days after the initial attempt, the SGC again attempts to contact Edora, with the same results: wormhole, but too closely covered to allow anything to survive the trip. Sam believes that the molten naquadah hardened just above the active event horizon, forming a sort of iris. Hammond considers the facts and declares Jack officiall missing in action. (A Hundred Days)
Three months later, Laira has let Jack know she's interested in him (by kissing him when he asked for a hint about what she was talking about), and Sam has finished building the particle-beam generator, and begun firing it through the wormhole at the shield covering Edora's stargate. (A Hundred Days)
Shortly thereafter, Jack and Laira have slept together, and the SGC has broken through enough for Teal'c to start digging by hand. Laira hears some radio chatter and eventually tells Jack, who runs for the stargate site and digs Teal'c out just before his air runs out. (A Hundred Days)
After the gate is dug out completely and placed to make travel easier (presumably), the Edorans trapped on Earth are returned to their village, and Jack leaves Edora for home. (A Hundred Days)
A batch of stories that Joe Spencer had sent off to 'New York magazines' are rejected, including one about Hathor and one about Seth. (Citizen Joe)
Several alien cultures accuse the SGC of stealing technology -- the SGC denies it categorically each time. (Shades of Grey)
The Tollans and Asgard approach the SGC independently with proof that the SGC was stealing technology from them. The Tollans, Asgard, and Nox were going to sever all ties with the SGC as a result. Hammond (and maybe Jack? He said 'we') convince them that it had to be the action of a rogue group, and they insist that the SGC apprehend the criminals themselves. The Asgard in turn insist that Jack be the only one involved. Jack and Hammond set up a plan for Jack to go undercover in the NID, keeping absolutely everyone out of the loop so all the reactions to his betrayal look right. (Shades of Grey)
As part of the scheme to infiltrate the rogue group, 0n a diplomatic mission to Tollana to formalize diplomatic relations, Jack apparently loses his temper over the Tollans's refusal to share technology and storms off, stealing a weapons-disabling device from a wall on his way out. (Shades of Grey)
Hammond 'discovers' what he's done and they have a shouting match at the briefing table about it, in front of the shocked rest of SG-1. Later, in front of Teal'c, Hammond tells Jack he has two options: early retirment, or court martial. Jack takes retirement. (Shades of Grey)
The day after he 'retires', Jack gets a visit from Daniel, whom he shuts down by cooly repeating his position on the need for technology and explaining that the Pentagon's decision not to allow a secondary SGC offworld -- with Jack in command -- showed the lack of commitment to the goals of attaining technology for the Earth's protection. (Shades of Grey)
After Daniel leaves, unhappily convinced that Jack meant what he said, Maybourne arrives to make Jack an offer: the ability to travel through the stargate to gain technology however and whenever he wants, for the good of the country. Jack kicks him out. (Shades of Grey)
Makepeace is assigned to be the new SG-1 leader. (Shades of Grey)
A week later, Jack calls Maybourne to ask for more information. Maybourne arrives and warns Jack that it's his last chance to back out. Jack doesn't. He arranges to retire offworld, ostensibly on Edora, then immediately goes to the planet where 'his' rogue NID unit is based, and takes command. (Shades of Grey)
His first mission, right after joining his unit, is to steal an invisibility device from an Asgard-protected world. Afterward, he arranges to make the drop for the SG mole himself, and sees Makepeace make the pickup. Thor beams in in time to catch the address Jack returns to, and the Asgard begin reclaiming their stolen property as Jack dials home and tells the NID members that their choices are to be arrested on Earth, or be taken by the Asgard. They choose arrest. (Shades of Grey)
Makepeace is the last to be arrested, by Jack personally. (Shades of Grey)
High Chancellor Travell, on Earth to witness the criminals being apprehended, assures Hammond and the others that they have regained the trust of their allies. (Shades of Grey)
Sam's cold dialing program for the stargate dialing computer gets its first hit, serendipitously dialing Bedrosia just as Nyan, a local archaeologist, was uncovering the gate there. (New Ground)
Jack, Sam, and Daniel are captured by the local military -- Teal'c avoids capture but is badly injured when he confronts a Bedrosian soldier (blinded, and Junior is hurt). (New Ground)
Nyan helps Teal'c recover, then helps him steal a shuttle and rescue the others. (New Ground)
SG-1 leaves almost all their gear behind, plus a naquadah reactor, when escaping Bedrosia. They take Nyan with them. He's granted refugee status, and Daniel offers him a job as research assistant.
Apophis attacks Chulak in his search for the harsesis child. (Maternal Instinct)
Apophis sends a group of eight Jaffa to Kheb to retrieve the child. They're killed by Oma Desala. (Maternal Instinct)
Bra'tac arrives at the SGC bearing Moac, one of his students, badly wounded in Apophis's attack on Chulak. This is the first the SGC knows of Apophis's survival of the destruction of Netu. (Maternal Instinct)
With Bra'tac's help, and the help of the Ancients's stargate map that Jack had programmed into the computer, the SGC figure out where Kheb was. SG-1, SG-2, and Bra'tac go to find the harsesis child, more than two days after Apophis's Jaffa die there. (Maternal Instinct)
Bra'tac, who had been feeling his years and wondering if it was his time to die, decides to keep living and fighting after hearing that he would have to die to begin his journey to oneness. (Maternal Instinct)
Daniel begins his path to ascension without realizing that's what he's doing, thinking he's just learning how to use his mind to protect the harsesis child, through the monk who was the curator/caretaker in Oma Desala's temple. (Maternal Instinct)
After a day of study with the monk in the temple, Daniel believes he can do many miraculous things, and when Oma Desala appears and shows him to the baby, he at first believes she's ready for him to take the child. Then he realizes she meant for him to understand that the child will be safer with her, and leaves him. (Maternal Instinct)
Oma Desala destroys the Jaffa who have come to take the child, and leaves Kheb for parts unknown. (New Ground)
The SGC discovers a world with a huge Mayan pyramid. When SG-1 goes to investigate, they find high levels of muon radiation inside, and a crystal skull. (Crystal Skull)
Daniel looks into the eyes of the skull, triggering an increase in the radiation levels. Teal'c shoots the skull to protect Daniel, who vanishes before the others's eyes. He's actually shifted out of phase with their physical reality. Jack, Sam, and Teal'c run for home to avoid dying by radiation -- all three wind up with radiation poisoning, but controllable levels. When Teal'c returns for the skull in hopes it will help lead them to the missing Daniel, Daniel follows him home.(Crystal Skull)
Eventually, the SGC brings in Nick Ballard, Daniel's grandfather, hoping that his previous experience with a crystal skull will help. Nick can see and hear Daniel, and once he's convinced Daniel isn't an hallucination, convinces the SGC to do as Daniel wishes -- return to the pyramid with Daniel and the skull, and allow the skull to finish what it started. (Crystal Skull)
Everyone but Teal'c is shifted out of phase, and one of the giant ghostly aliens that Nick had seen almost 30 years earlier appears. He introduces himself as Quetzelcoatl, and invites Nick to stay and learn. Nick accepts. (Crystal Skull)
Daniel has an appendectomy. (Nemesis)
Replicators infest the Biliskner during a battle. Thor gets the crew off, but stays behind to try to stop the Replicators. They get into the computers, find out about Earth, and put the ship on course for it. (Nemesis)
On his way to get in some fishing during SG-1's downtime while Daniel recovers from his appendectomy, Jack is beamed aboard Thor's ship. (Nemesis)
Jack, then Sam and Teal'c, see Replicators for the first time. Jack and Sam learn how to use Asgard stone controls to use the hologram and computer-information-recall technology. Sam also learns how to use the transporters. (Nemesis)
Teal'c nearly dies in space when Replicator acid eats through his air tank. (Nemesis)
The US moves to Defcon 3, and the president decides to tell the world what's going on if the Biliskner lands. When the Biliskner begins a controlled entry, Hammond suggests moving to Defcon 2 -- they do. (Nemesis)
Sam, Teal'c, and Jack beam up the stargate from the SGC (the Giza gate) to use as an escape route. Hammond orders the second (beta) gate (the Antarctic gate) uncovered, moved, and installed at the SGC as quickly as possible. (Nemesis)
SG-1 blows up the Biliskner's deceleration drive, forcing it into an uncontrolled entry that burns the ship up, and escapes through the stargate with Thor (in a stasis pod, near death). (Nemesis)
The Giza gate lands in the Pacific, along with a sole surviving Replicator and the scattered remains of the Biliskner. (Nemesis)
The Antarctic gate becomes the program's sole stargate. Hooked up to the computer, just like the original gate. (Nemesis/Small Victories)
ca. 2000 | early 2000 | mid-2000 | late 2000 | late 2000 / early 2001
Note: This section is not complete. I'll be going back through the season and filling it in properly when I get a chance.
These are events that I know happened in 2000, but I don't know where they fit in the chronology of the events of fourth season.
The Tiranians steal some naquadria from the Andari Federation and begin trying to build a naquadria bomb, to catch up with Kelowna's technical capabilities. (Fallout, Homecoming)
A rogue NID sleeper cell begins work on a project to create a human/Goa'uld hybrid, using DNA from Sekhmet (found in a canopic jar). (Resurrection)
Jack, Sam, and Teal'c are trapped offworld for two weeks, when it takes the SGC that long to install and correctly hook up the Antarctic gate in place of the Giza gate that crashed with Thor's ship. (Small Victories)
The Russians salvage the Giza gate from the ocean's floor and begin their own stargate program, using the Giza DHD to dial addresses. (Watergate)
The Eurondans make contact with the SGC and promise to trade some very useful technology in return for heavy water to help them power their bunkers and weapons. Jack is all for it (despite Daniel's cautions) until he realizes that the Eurondans are genetic puris
