The World of Code Geass.

The World History of the Code Geass Universe differs markedly from our own, mostly in the outcome of major battles and war, but also in the appearance of materials like Sakuradite and immortals like C.C..

Calendars

The Imperial Calendar refers to the date and setting Code Geass uses in the English version, in which years are labeled as a.t.b or "Ascension Throne Britannia". It is set to the date the first Celtic super-king, Alwin I, was elected by the united British tribes to battle Rome, becoming the first member of the modern Britannian imperial family. This calendar is used by the Holy Empire of Britannia. It functions similarly to the standard Gregorian Calendar (B.C.E./C.E. or alternatively B.C./A.D.), but starts half a century earlier.

As referenced in Code Geass: Akito the Exiled, the Europia United shown is using the French Republican Calendar. The first entry in Leila Malcal's journal in the first episode of Code Geass: Akito the Exiled is dated as "Revolutionary Calendar, year 228, Floréal 18th" (a.t.b. May 7, 2017), and in the second episode "Revolutionary Calendar, year 228, Prairial 7th" (a.t.b. May 26th, 2017).

As the events of the first episode of Akito the Exiled occur in the year 2017 a.t.b., it is safe to assume that the Revolutionary Calendar starts with the Storming of the Bastille, which occurred at July 14, 1789 (2017 - 228 = 1789). It revealed as set on same year in our world. But revealed a.t.b. and A.D. have differences officially.[1]

Following the death of Emperor Lelouch at the hands of Zero, a new calendar system is adopted from the following year on, referred to as Light Sum.

The calendar was established by Ricardo von Britannia I.

    • C.C. is born.
  • 17th Century a.t.b.
