There are actually more than 365 days in a year!  It actually takes 365 days and six hours for the Earth to revolve around the Sun. The extra six hours accumulate into an entire day every four years (6 hours x 4 = 24 hours or one day).  A “leap year” will contain the extra 366th calendar day. The extra day is added as February 29, which only exists in a leap year.   This year, 2012, is a Leap Year. The term “leap year” comes from the fact that in England, the extra day every 4 years was not recognized by English law and was “leapt over” or ignored.
