Over 2,000 years ago Julias Caesar, the leader of the Roman Empire, invented the leap year, adding an extra day to our calender every four years. The Julian calender had only one rule; that every year that was evenly divided by the number four would be considered a leap year.
His model was eventually corrected 1,500 years later to include several more rules. The year must still must be divisible by four but if it is divisible by 100 it must also be evenly divisible by 400. Because of this, certain leap years occur every three years rather than four.
So why do we need leap years anyway? The extra day keeps our Gregorian Calendar in line with the Earth’s revolutions around the sun. Without an additional day in February every four years, we would lose about six hours off of our calender every year. It doesn’t sound like much, but after 100 years our calender would be off by about 24 days!
