February 29th, also known as Leap Day, is an extra calendar day that is observed every four years. It takes about 365 days and 6 hours for the earth to completely revolve around the sun and after four years, once an extra 24 hours has built up, one additional day is added to keep the calendar year synched up with the astronomical year. Pretty neat, right? In honor of this past week’s extra day, we’ve featured some fantastic jumping photos that have been shared with Instagram.
