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

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.

Dumecian Calendar
The Dumecian Calendar has the same day length and weekdays as the Araxian Calendar (indeed, these features both originated with the Dumecian Calendar), but it does not name individual months. In addition, the year begins in spring instead of summer.
