A Leap day is an additional day in the calendar during a leap year, which occurs once every four years. A leap year is divisible by four, except for years divisible by 100 but not by 400, meaning that the years 2000 and 2400 are leap years, but the years 1700, 1800, and 1900 were not, even though they were divisible by four.
The purpose of leap day is to keep the calendar year in sync with the astronomical year, which is the time it takes for the Earth to complete one orbit around the sun.
The astronomical year is approximately 365.24 days long, which means that the calendar year, which is 365 days long, is slightly shorter. Adding an extra day is necessary for the calendar to stay in sync with the seasons, resulting in events traditionally associated with particular times of the year, such as the spring equinox or the summer solstice, which would gradually shift over time.
Leap day is traditionally associated with various customs and superstitions. In many cultures, it is considered unlucky to be born on leap day, and people born then earn the nickname "leaplings" or "leap year babies."
Leap day is also sometimes associated with events or occasions that only occur once every four years. For example, in some countries, elections are held only in leap years, and the Summer Olympics and Paralympics are also held on a four-year cycle, with leap years marking the midpoint between games.
