Zerithian Calendar

Established during the First Zerithian Empire to replace the then current Traditional Zerithian Calendar, the Zerithian Imperial Calendar (as it is formally known) counts years from the founding of the Empire, which is designated the 1st Imperial Year (conventionally written as 1 IY).

Months
After the third century reformation of the calendar, the year was fixed at 365 days, corresponding to Zerith's tropical year. Except in the sub-tropical southern region of Westen, Zerithian lands all experience distinct seasons, which are reflected in the division of the calendar year into four periods. Each seasonal period has three thirty day-long months and begins with an intercalary holiday, totally 91 days. There is an additional intercalary holiday at the end of the year, bringing the total to 365 days.

The divisions for the year are:

Summer - begins with New Year's Day
 * 1) Hochsom
 * 2) Versom
 * 3) Damsom

Autumn - begins with Fading
 * 1) Ernat
 * 2) Brache
 * 3) Kalsom

Winter - begins with Winter's Eve
 * 1) Spersom
 * 2) Matt
 * 3) Sansom

Spring - begins with Sun Day
 * 1) Ploughing
 * 2) Planting
 * 3) Bebausom

The year finishes with Year's End Day

Weeks
Weeks are five days long, and don't include intercalary days. Therefore, each month always start and end on the same day of the week. The days are:


 * 1) Enpas
 * 2) Tranpas
 * 3) Midpas
 * 4) Markpas
 * 5) Einpas
