Leap year

A leap year is a calendar year that includes an extra day-February 29th-to help synchronize the calendar year with the astronomical year or seasonal year. This adjustment accounts for the fact that a solar year is approximately 365.25 days long. Leap years occur every four years, with some exceptions based on century years, ensuring our calendar remains accurate over time.
