The

divisible by

2000 and divisible by

5000 have never been adopted by any

country, anywhere. It all relates back to the

Gregorian Calendar. So 2000, is a leap year. It looks like

Microsoft got this one right. "The 2000 not a leap year," though thoroughly debunked is another of those

urban legends to pass around the net for many years.

One should note that a year is a leap year if it is divisible by 4. Unless it is divisible by 100; however, if it is divisible by 400 it is a leap year. There are no further rules.
