THE IMPERIAL CALENDAR
THE IMPERIAL CALENDAR
The empire, variously called Ziru Sirkaa, the Re-Established Grand Empire of the Stars, the Third Imperium, the Imperium, the Empire, or simply the empire, was re-established as the interstellar community in this particular region emerged from the thousand-year Long Night.
The Imperial Calendar takes as its reference point the day and year in which the Imperium was declared: the first day of Year Zero. Dates are expressed as a three-digit day followed by a three-digit year: The Imperium was declared on 001-000. The day is often omitted in a year reference: Anguistus became eighth Emperor in 326.
Dates before the Year Zero are negatives: The First Imperium fell in –2204; Cleon Zhunastu was born in –57.
For finer detail, time on a 24-hour clock may be prefixed followed by a space. 0000 001-000 is beginning midnight of the first day of the calendar. 0800 045-123 is the eighth hour of a specific morning. 2000 045-123 is the twentieth hour of the same day. Subtract 12 to convert to traditional clock time. Local star- or sun-oriented times may vary.
