Every 4 years we have a day added to our calendar, February 29th. It is called Leap Day which occurs during Leap Year. Why do we have Leap Year? Simply because it does not take exactly 365 days for the Earth to revolve around the Sun. The exact amount of time it takes the Earth to makes its journey is 365 days 5 hours 48 minutes and 46 seconds. So every 4 years we need to make an adjustment to the Gregorian Calendar, the modern day calendar, and add a 366th day!

Some pretty interesting facts about Leap Year:

the year must be evenly divisible by 4
the year can not be divisible by 100, unless…
it is also divisible by 400
Ahh we learn something new everyday! Hope we shed a little light on why we have Leap Year. Enjoy your extra day and do something awesome!
