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 28 days in common years and 29 days in leap years.
February is the third month of winter in the Northern Hemisphere. In the Southern Hemisphere, February is the seasonal equivalent of August in the Northern Hemisphere (which is the third month of summer).
February starts on the same day of the week as March and November in common years, and on the same day of the week as August in leap years. February ends on the same day of the week as October every year and January in common years only. In leap years, it is the only month that ends on the same weekday it begins.
