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, A year in the Earrachian Calendar lasts through all four seasons. 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.

Components
The Earrachian Calendar has the following components:

The calendar was calculated based on the following assumptions:
 * Year
 * Ràith/Season
 * House
 * Month
 * Day

This means that there are 288 days, or 36 months, in an Earrachian Year.
 * A lunar cycle (a month) lasts for 8 days
 * A season lasts for 9 months
 * A year lasts for 4 seasons

Ràith
The calendar divides its years into 4 ràiths, 3 of which are named after the Worldly Deities of the Madacuain:


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

Each ràith lasts for 72 days, or 9 months.

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

Each house lasts for 3 months or 24 days.
 * 1st House
 * 2nd House
 * 3rd House

Month
The moon goes through 8 lunar phases that changes every day. This means that a month in the Earrachian calendar lasts for 8 days.

The phases of the moon are:


 * Full Moon
 * Waning Gibbous
 * Last Quarter
 * Waning Crescent
 * New Moon
 * Waxing Crescent
 * First Quarter
 * Waxing Gibbous

Corresponding to the amount of houses in a ràith, every lunar phase would repeat 3 times in each house before a transition to the next house.
