The date calendar is believed to have originally consisted of some months that were 29 days long and other months that had 30 days. The date calendar started the year in March and consisted of 10 months, with 6 months of 30 days and 4 months of 31 days. The winter season was not assigned to any month, so the calendar year only lasted 304 days with 61 days unaccounted for in the winter.
