February is the second month of the year in the Julian and Gregorian calendars. It is the shortest month and the only month with fewer than 30 days. The month has 29 days in leap years, when the year number is divisible by four (except for years that are divisible by 100 and not by 400 in the Gregorian calendar). In common years the month has 28 days.
February starts on the same day of the week as both March and November in common years, and August in leap years.
