“Leap Years keep our calendar in alignment with the Earth’s revolutions around the Sun. It takes the Earth 365.242199 days to circle the Sun once. Without adding a February 29th every 4 years, we would lose almost six hours every year. After 100 years, our calendar would be off by approximately 24 days!” (timeanddate.com)
Happy Leap Day!
