What is a leap year?

Have you ever imagined building a snowman in the middle of July? That is exactly what could happen if we didn't have leap years! Join Mira and Finn as they uncover the mind-bending space secret behind February 29th. You will discover that a year isn't actually a neat 365 days long—it takes the Earth 365 and a quarter days to travel all the way around the Sun! Without that extra quarter of a day, our calendar would slowly drift away from the seasons until summer turned into winter. Learn how the Roman leader Julius Caesar tried to fix this giant mess by adding one extra day every four years. But nature loves a tricky fraction, and his math was off by just eleven minutes! Find out how Pope Gregory XIII made an even cleverer rule, and hear the wild true story of why the people of Britain once had to skip eleven whole days in 1752—going to sleep on September 2nd and waking up on September 14th! Get ready to bend your brain and travel through time as we explore the incredible science of calendars!
