Who created the idea of Leap Year?

• Julius Caesar:Leap Year was “invented” back in the first century BC, when Julius Caesar and his team of astronomers noticed that their Roman calendar had somehow slipped out of sync with the seasons. They came up with a 365-day calendar that would sometimes add an extra day to the last month of the year, which was February. The purpose of adding an extra day to February every four years is to sync up the 365-day Gregorian calendar with the solar calendar, which is 365 days, 5 hours, 48 minutes, and 46 seconds long — the (near) exact amount of time it takes the earth to revolve around the sun.
