A COG calendar during the Pendulum Wars.

Little information is known about the planet Sera's calendar and seasons for both the Locust and Seran people. The known months/Seasons for the people are as follows:

The Seran Calendar and SeasonsEdit

Due to the significance of the Locust attack on Emergence Day, Serans adopted a new date system, designating years Before Emergence (B.E.) and After Emergence (A.E.).[1] There are roughly 420 - 460 days in a Seran year, 30 - 38 days in a Seran month, 10 days in a Seran week, and 26 hours in a Seran day.[2]

It is unknown what Serans used to label or number years before Emergence Day. However, the Serans were nearing the end of the 60th century when Emergence Day occurred. Specifically, Emergence Day was in the year 5992.[3] The years before 5992 were then labeled as B.E., and the years afterward were labeled A.E., with 5992 being labeled as 0 B.E. or 0 A.E., or Emergence Year.

Locust CalendarEdit

Translation of symbols clockwise: Queen, Fire, Drone, Leviathan, Danger, Nemacyst, Imulsion, Water, Human, Kryll, Secure, Seeder.

The Locust Calendar is similar to that of a sundial and is calibrated by the the flow of Imulsion[19]. For every season, it has an opposite. Each full cycle of the calendar is "one cycle", which is equivalent to one Seran year.[20]

  • Fire (Water)

Human Analysis on the Locust CalendarEdit

"Baird here.

I think this thing's like the Locust equivalent of a calendar or a clock... it says something about 'every season having its opposite,' and I also see some glyphs for 'Nexus,' 'Queen,' and maybe 'Imulsion'... can't quite tell.

I'm guessing it has something to do with the ebb and flow of Imulsion, but I'd have to do a lot more research to confirm that.

Considering that I'm about, oh, 3 kilometers deep, right square in the guts of the enemy, you'll have to forgive me if my vast empirical skills aren't exactly at their finest right now."[19]
