Editing Calendar

In Undersided, the '''year''' is 301.3063 local days, the lunar '''month''' is 32.762 local days, and the local '''day''' is 25.758 real-world hours. This means that a local year is about 323.377 Earth days. 

With this in mind, various calendar systems have emerged.

=== Year numbers ===
The conventional starting date for the calendar is what is now [[Timeline/BF|1321 BF]]. However, in modern times, due to [[Siegetev]]'s [[Rahazun|Rahazuna]] power projection, SR (years since the founding of Rahazun) is commonly used instead. The yarov of [[Yarzon-Ebott]] used the X calendar (0 X = 662 SR).

== [[Indadvi]] calendar ==
The Indadvi calendar uses 10 months, each of which are 30 days, except for the last one which is 31 or 32 depending on the year.

== [[Zemirabel]] calendar ==
The calendar used by the [[Avangani]], who live near the equator and live on much shorter timescales compared to other races, tracks the moon as opposed to the sun, with 3 months being 32 days long before the fourth is 33. Years are not counted at all.
