The Araxian Calendar is a solar calendar created by [[Emperor Araxius I]] at the founding of the [[Araxian Empire]]. It is in use throughout the Empire and its former territories, as well as in [[Belgrit]].

=== Year ===
 +
The main Araxian year is 384 days long, beginning with 1 Vymera on the summer solstice (as measured at the observatory of the [[Araxian Academy of Arcane  Sciences]]) and ending on 32 Jaaldir. The names of the months are taken from the 12 major [[Religion|deities]] of the Araxian pantheon.

==== Heptinus ====

You may have noticed that the Araxian year is 7.125 days shorter than the mean solar year. How does that work?
 +
 
 +
Between Araxian years, an intercalary period of 7-8 days (the ''Heptinus'') is observed before the next year begins. The Heptinus is 8 days long preceding years divisible by 8 and 7 days long otherwise. It is technically not part of any year, but it is often treated as the end of the previous year.
 +
 
 +
As a result, although the Araxian year is only 384 days long, the number of days from one summer solstice to the next varies from 391 to 392.

The Dumecian Calendar has the same year length and weekdays as the Araxian Calendar, but it does not name individual months. In addition, the year begins in spring instead of summer, and the intercalary period is 3-4 days instead of 7-8 and occurs between winter and spring instead of between spring and summer.

Timekeeping & Celestial Mechanics

A mean solar year on Delgar is approximately 391.125 mean solar days long. Thus, the 391-day Araxian calendar must add 1 leap day every 8 years to prevent drift.

Delgar Unit Conversion Earth Equivalent
1 year 391.125 days
1 day 24 hours ~24 hours
1 hour 64 minutes ~60 minutes
1 minute 64 seconds ~56 seconds
1 second ~0.88 seconds

Araxian Calendar

The Araxian Calendar is a solar calendar created by Emperor Araxius I at the founding of the Araxian Empire. It is in use throughout the Empire and its former territories, as well as in Belgrit.

Year

The main Araxian year is 384 days long, beginning with 1 Vymera on the summer solstice (as measured at the observatory of the Araxian Academy of Arcane Sciences) and ending on 32 Jaaldir. The names of the months are taken from the 12 major deities of the Araxian pantheon.

Heptinus

You may have noticed that the Araxian year is 7.125 days shorter than the mean solar year. How does that work?

Between Araxian years, an intercalary period of 7-8 days (the Heptinus) is observed before the next year begins. The Heptinus is 8 days long preceding years divisible by 8 and 7 days long otherwise. It is technically not part of any year, but it is often treated as the end of the previous year.

As a result, although the Araxian year is only 384 days long, the number of days from one summer solstice to the next varies from 391 to 392.
