Neil deGrasse Tyson Sets the Record Straight on Leap Year

On Twitter today, famed astrophysicist Neil deGrasse Tyson, one of the world’s celebrity scientists, released a video he shot for National Geographic, giving you more facts than you ever wanted to know about the science and math behind the phenomenon of Leap Year. Every four years, we are treated to a 366-day year, he explains, because it takes 365 ¼ days for the Earth to circle the sun. And rather than count that quarter-day every year, we just save them up until we have a full day, and then tack it onto the end of February (why February? Maybe we felt bad that it only ever gets 28 days).

But in addition to the usual fact, Tyson also explains why certain scheduled years don’t have leap years. It’s all very fascinating and presented in Tyson’s accessible, inimitable, conversational style. Watch the below video, and learn a bit about your planet. After all, we live here.
