29 February 2012 The last 2 digits of the year should be multiple of 4. Divide the last 2 digits and the remainder should be 0

2012 - Last 2 digits 12. Divided by 4. Remainder is 0

2008 - Last 2 digits 08. Divided by 4. Remainder is 0.

29 February 2012 In general terms the algorithm for calculating a leap year is as follows...

A year will be a leap year if it is divisible by 4 but not by 100. If a year is divisible by 4 and by 100, it is not a leap year unless it is also divisible by 400.

Thus years such as 1996, 1992, 1988 and so on are leap years because they are divisible by 4 but not by 100. For century years, the 400 rule is important. Thus, century years 1900, 1800 and 1700 while all still divisible by 4 are also exactly divisible by 100. As they are not further divisible by 400, they are not leap years.
