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.
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.
Each day is divided into eight three-hour units called "phases":

== Araxian Calendar ==
The current calendar in use throughout most of the world is the Araxian Calendar. The major holdouts are [[Dumecia]] (see [[Calendars#Dumecian Calendar|Dumecian Calendar]]) and [[Dhol]] (see [[Calendars#Dhol Calendar|Dhol 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 ===
=== Year ===
The Araxian year is 384 days long, beginning with 1 Vymera on the summer solstice (in [[Araxia]]).
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.

At the end of each year, an intercalary period of 7-8 days (the ''Heptinus'') is observed before the next year begins.
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.
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.
