Covenant Battle Calendar

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. The Battle Calendar is measured in Cycles and then broken down further into Units. It appears to be the Covenant equivalent of the Military Calendar employed by the UNSC.
