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.

This resulted in scribes and scholars referring to them as "the first month", "the fifth month", etc. [citation needed] To keep the lunar year of 354 days in step with the solar year of 365.242 days an extra month was added periodically, much like a Gregorian leap year. [10]

For example, 2000 was a leap year but 1700, 1800, and 1900 were not. The next skipped leap year will be in 2100. Why is it called a leap year? A typical calendar year is 52 weeks and one day long ...
A table for the Gregorian calendar expresses its 400-year grand cycle: 303 common years and 97 leap years total to 146,097 days, or exactly 20,871 weeks. This cycle breaks down into one 100-year period with 25 leap years, making 36,525 days, or one day less than 5,218 full weeks; and three 100-year periods with 24 leap years each, making 36,524 ...
A leap year is a year in which an extra day, Feb. 29, is added to the calendar. It's called an intercalary day. It occurs about every four years, but there are exceptions (we'll get to that later).
