Calendar System at Gundam

Gundam's Calendar SYSTEM

The majority of Gundam, including the earliest series, occur in the Universal Century (UC) calendar, with later series set in alternate calendars or timelines mostly unrelated to the UC system (at least three of these calendar systems were actually initially numbered after the year that the series premiered, with 1979's Mobile Suit Gundam taking place in UC 0079, 1995's Mobile Suit Gundam Wing in After Colony 195, and 2007's Mobile Suit Gundam 00 taking place in 2307).

Mobile Fighter G Gundam takes place in the Future Century (FC), where space colonies have gained the upper hand over Earth, consequently attempting to put an end to the internal power struggles now plaguing the planet.

Mobile Suit Gundam Wing takes place in the After Colony (AC) calendar system, set after the foundation of the first space colony, where Earth firmly maintains repressive control over its colonies.

After War Gundam X takes place in the After War (AW) timeline, set after the conclusion of the 7th Space War, where the Earth is devastated by massive colony drops.

∀ Gundam takes place in the CC (正歴 Seireki^?) calendar system, which director Yoshiyuki Tomino intended as the distant future of all previous timelines. The CC sees the colonies becoming much stronger than the Earth, but unlike the FC timeline, takes a more aggressive stance towards it. The English acronym of CC is Correct Century (コレクトセンチュリー), in the official Japanese ∀ guide book.

Mobile Suit Gundam SEED, its sequels, and spinoffs take place in the Cosmic Era, with CE referring to the years after the foundation of the first space colonies.

Mobile Suit Gundam 00, is so far the only series to occur during the non-fictional Anno Domini (西暦 Seireki^?) timeline. This is reflected in the show with a worldview that more reflects the modern world, and the presence of real-life conflicts and rebel groups such as the Real Irish Republican Army and the Liberation Tigers of Tamil Eelam.

Mobile Suit Gundam AGE takes place in the Advanced Generation (AG) calendar system, which is set after hundreds of years of space colonization and is characterized by the end of all wars in the Earth sphere and a period of peace before the sudden attack of the UE.

Bandai and Japanese-speaking fans unofficially refer to projects not directly related to the first Gundam series or its staffers (such as Gundam Sentinel and Mobile Fighter G Gundam) as "Another Gundam" stories, and to projects made after 1989 as "Heisei Gundam" stories. On a survey for a video game that would become Gundam: True Odyssey, the Cosmic Era series (including Mobile Suit Gundam SEED Astray) were collectively referred to as "21st Century First Gundam" (a reference to the original Mobile Suit Gundam series). English-speaking fans have used the term "Alternate Universe" ("AU" for short) as a nickname for the stories that do not take place within the Universal Century timeline, but this is made unofficial for use in Japan.
