What is leap day all about?

Leap Day, occurring on February 29, is an extra day added to the calendar every four years to help synchronize the calendar year with the astronomical year. This adjustment accounts for the fact that a complete orbit of the Earth around the Sun takes approximately 365.24 days, necessitating the addition of a leap day to maintain alignment. The practice is part of the Gregorian calendar, established in 1582, and ensures that seasonal events stay consistent over time. Leap Day is often celebrated with various traditions and events, particularly among those born on this unique date, known as "leap year babies."
