The Weather History for February 29th

So why exactly do we have leap years? Every four years an extra day -- Feb. 29 -- is added to align the calendar year with the Earth's motion around the sun. A calendar year is 365 days, but it actually takes the earth 365 days, 5 hours, 48 minutes and 46 seconds. Therefore, every four years, the extra time adds up to an extra day.
