What is a Leap Year? A leap year is a year that has one extra day in it. A leap year occurs roughly every four years. Most years have 365 days, but a leap year has 366 days. The extra day is added onto the end of the shortest month, February; in a leap year, February has 29 days (instead of its usual 28 days). February 29 is called leap day.
