Will 2012 be a leap year and was 2000 a leap year?

2012 is a leap year.

2000 was a leap year, and so were 2004 and 2008. Leap years will fall in almost every year that is evenly divisible by 4.

The exception is for years that end in "00" (1900, 2000, 2100). These will not be leap years unless, like 2000, they are also evenly divisible by 400.
