Oh, silly Earth. Instead of taking a nice, round 365 days to revolve around the sun, our planet lags a bit, actually making the complete circle in 365¼ days. To keep our calendar in tune with that asymmetrical fact, we have Leap Year, and every four years (or so), February 29 makes an appearance. Clearly, Leap Day is special, and deserves celebrating with a drink! There’s even a special Untappd badge for the occasion. Check out our rundown of shenanigans and events taking place tonight.
