Covenant Battle Calendar
From Halopedia, the Halo wiki
The Covenant Battle Calendar is the standardized timekeeping calendar employed by the Covenant military, intended to assist in chronological coordination between ships, units and planets in different systems with different measures of time. It is the Covenant equivalent of the Military Calendar employed by the UNSC.[1]
The calendar is measured in cycles and then broken down further into units.
Terms used in the calendar
Unit
A unit is a Covenant term referring to either a standard unit of measurement, which is comparable to a foot in the human imperial system,[1] or a standard unit of time, comparable to an hour on Earth.[2] The meaning of the term is dependent on the context in which it is used.
Cycle
A cycle is a Covenant unit of time based on the Forerunner temporal unit of the same name.[3] Containing 265 units, one cycle is equal to a single artificial day on the Covenant's holy city of High Charity.[4][5]
