Leap day is here! 2012 is a leap year, with an extra day. Last one was 2008, next one is 2012.
From Wikipedia:
February 29, also known as a leap day in the Gregorian calendar, is a date that occurs in most years that are evenly divisible by 4, such as 2004, 2008, 2012 and 2016. Years that are evenly divisible by 100, but not by 400, do not contain a leap day; thus 1900 did not contain a leap day while 2000 did. Years containing a leap day are called leap years. February 29 is the 60th day of the Gregorian calendar in such a year, with 306 days remaining until the end of the year.
My dad has me doing M100s (well, we can’t do 100 of them). Part of the exercise is a leap!
