Today is Leap Day- a day added to the common year- which has 365 days, making the leap year consist of 366 days.
But why do we need a Leap Year?
KOZI’s Hayli Libbey Thompson tells us more.
In addition to today- leap day- 2012 will also bring us a leap second. On the night of June 30th there will be one more second in the day.
That may not sound like much, but it is a vital second. While the leap year keeps the calendar in order, the leap second keeps the clock in order by closing the gap between time measured by atomic clocks, and time measured by the daily rotation of the Earth.
