February 29th is special because it is a leap day, which occurs every four years in order to keep our calendar in alignment with the Earth's orbits around the Sun. It compensates for the fact that our planet takes approximately 365.24 days to complete a full orbit around the Sun – a little more than a regular 365-day year. The addition of a leap day helps ensure that seasons continue to start on roughly the same day each year.
