Everyone knows about leap years, but it's easy to forget why we have them. Every four years, we add an extra day to the month of February to keep our calendar in sync with the earth’s revolutions around the sun.
It takes 365.242199 days for the earth to complete a full rotation around the sun. Our calendar, however, marks out a mere 365 days a year. If we did not add a day every four years, we would lose six hours from our calendar every year, or 24 days in the course of 100 years! We don’t know about you, but we can use all the extra time we can get.
