February 29 is a rare birthday because it occurs only in a leap year, which happens every four years. Leap years are needed to keep our calendar in alignment with the Earth's revolutions around the Sun. Without an extra day every four years, our calendar would be off by about six hours each year. So, if you're born on February 29, you have a unique birthday that's celebrated once every four years!
