According to Wikipedia, a leap year is a calendar year containing an additional day added to keep the calendar year synchronized with the astronomical or seasonal year. It happens every 4 years.
Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year slip over time with respect to the events' date of the year it is supposed to track.
Check out this dubious folk tradition about Leap Year instead:
In Ireland and Britain, it is a tradition that women may propose marriage only in leap years. While it has been claimed that the tradition was initiated by Saint Patrick or Brigid of Kildare in 5th century Ireland, this is doubtful, as the tradition was not substantiated before the 19th century.
