    A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) compared to a common year.

    In the last 8 years, the intercalation took place with the month of Mercedonius only 27 days, except the last intercalation which did not happen.

    A leap year has one more day, so the year following a leap year begins on the second day of the week after the leap year began.

    The solar year does not have a whole number of lunar months (it is about 365/29.5 = 12.37 lunations), so a lunisolar calendar must have a variable number of months per year. Regular years have 12 months, but embolismic years insert a 13th "intercalary" or "leap" month or "embolismic" month every second or third year.
