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.
