At Sosigen’s suggestion, this calendar was based on the movement of the Sun rather than the Moon. To correct for seasonal changes, Sosigenes calculated a year of 356.25 days. Thus, while a year that is not divisible by 4 is 365 days long, the extra quarter days of this year are added to the 4th year and the leap year is increased to 366 days.
