Earrachian Calendar

The Earrachian Calendar is a calendar used in the Redorivan state of Earrach. The calendar tracks both Eldham's cycle around the Sun, which is known through the passing of the four seasons in Earrach, and the Moon's cycle around Eldham, making it a lunisolar calendar. Similar to the Elder Calendar, The Earrachian calendar designates 4 days (in real life) as one year. The difference lies in its reference epoch and designation of new years.

Properties
Whereas the Elder Calendar references the start of Rathnir, the Earrachian Calendar reckons time from the construction of the Citadel of Dùn Beinne, which began at springtime 3100 years before the start of the Paxian Period. This means that Year 0 during the start of the Elder Calendar marks year 5179 of the Earrachian Calendar (Abbreviated EY for Earrachian Year).

The construction of the citadel being at springtime means that instead of the Elder Calendar's winter, a new calendar year for the Earrachian calendar would happen at the beginning of spring. This means that Winter of 0 TE would translate to Silence, 5179 EY, whereas Spring of 0 TE would be Earrach, 5180 EY.

Subdivisions
The Earrachian Calendar has the following subdivisions:

Based on the following assumptions:
 * Year (288 days, or 36 months)
 * Ràith/Season (72 days, or 9 months)
 * House (24 days, or 3 months)
 * Month (8 days)
 * Day


 * 20 minutes in real life equates to an in-game day
 * A lunar cycle (a month) equates to 8 in-game days
 * 4 days in real life equates to an in-game year

A year in the calendar would be equal to 288 days or 36 months.

The calendar divides its years into 4 ràiths, 3 of which are based on the Worldly Deities of the Madacuain:


 * 1) Earrach (Spring)
 * 2) Samhradh (Summer)
 * 3) Oharan (Fall)
 * 4) Silence (Winter)

Each ràith would last for 72 in-game days, or 9 months.

A year is also divided into 12 houses, drawing from the myth from the Moray clan that 12 Whales of Creation were present during the birth of the universe instead of the Madacuain's 13. Each house lasts for 3 months or 24 days.

Each ràith is divided into 3 houses. The names of houses in each season are as such:

(For example, 10.30 am of June 30, 2022 would yield an Earrachian date of "2nd House of Oharan, 5340 EY")
 * 1st House (00.00 - 07.59)
 * 2nd House (08.00 - 15.59)
 * 3rd House (16.00 - 23.59)
