Timeline of Stargate


 * This article provides a timeline of events in the story of Stargate, by date.

The science fiction universe of Stargate, comprising a well-accepted canon of the film Stargate (1994), and the subsequent television shows Stargate SG-1 and Stargate Atlantis, has an internal chronology that underlies all of the related media. A combined timeline of the story is given below, with the real-time dates of the portrayed events determined by extrapolation from temporal references within the productions.

Although the film was set in the "Present Day", 1994 at its release, the subsequent TV shows provide an alternate dating system. Because the show is so well accepted as a canon continuation of the story, particularly by MGM (who own the rights to the franchise), the dating system described in the show is used in this article. Furthermore, most of the story of Stargate comes from the TV shows, and so they take precedence. The dating system of the show portrays events as taking place simultaneous, or at least in the same year as, the airdate of each episode. As the first episode aired on July 27, 1997, and the show begins one year after the events of the film, the film's "Present Day" is reinterpreted as 1996.

From indications in the show, each season of it is intended to correlate to one year in the show's story (and each season takes one year to air). For example, in Season 9, many characters mention how it's been "8 years" since they first came into conflict with the Goa'uld (beginning of Season 1). Using this information, it is possible to extract timelines based on information stated in episodes and also the relative positioning of the episodes throughout a season.

Season and movie settings
Stargate Infinity is set approximately 30 to 40 years after the SG-1 team first used the Stargate (Stargate SG-1: "Children of the Gods").
