Season and festival

The insistence on keeping Passover in spring is why the Hebrew calendar is lunisolar rather than purely lunar, and the nineteen-year cycle of leap months is its solution. The months structure the Jewish year of remembrance, fasting and rejoicing, and the calendar's era is counted from a traditional date of creation.

The atlas gives each month its place in the year, its festivals, and its character. The Hebrew months belong with the other calendars gathered under Calendars & Time, and their festivals connect to the holiday category.
