2012 is a Leap Year闰年

Dean

A leap year consists of 366 days, as opposed to a common year, which has 365 days.
During Leap Years, we add a Leap Day, an extra – or intercalary – day on February 29. Nearly every 4 years is a Leap Year in our modern Gregorian Calendar. February in a leap year has 29 days instead of the usual 28.
