A mean solar year on Delgar is approximately 391.125 mean solar days long. Thus, a leap day must be added every 8 years to prevent drift.
 +
Each day is divided into eight three-hour units called "phases":

The 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]]). The names of the months are taken from the 12 major [[Religion|deities]] of the Araxian pantheon.

You may have noticed that the Araxian year is 7.125 days shorter than the mean solar year. How does that work?
 +
 
 +
At the end of each year, 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 not considered to be part of any 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.

Timekeeping & Celestial Mechanics

A mean solar year on Delgar is approximately 391.125 mean solar days long. Thus, a leap day must be added every 8 years to prevent drift. Each day is divided into eight three-hour units called "phases":

Phase Earth Time (Equinox) Marker
Dawning 5 AM to 8 AM Sunrise
Morning 8 AM to 11 AM
Noon 11 AM to 1 PM Noon
Afternoon 3 PM to 6 PM
Evening 5 PM to 8 PM Sunset
Dimming 8 PM to 11 PM
Dreaming 11 PM to 2 AM Midnight
Dewing 2 AM to 5 AM

More precise timekeeping is rare on Delgar, but when it is done, it looks like this:

Delgar Unit Conversion Earth Equivalent
1 year 391.125 days
1 day 24 hours ~24 hours
1 phase 3 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 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). 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?

At the end of each year, 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 not considered to be part of any 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.
