When is the Next Leap Year?

The next leap year will occur in 2012. Three criteria are used to determine leap years in the modern Gregorian calendar, used by most countries. If a year is divisible by four, it is a leap year, unless it is also divisible by 100. However, if a year is divisible by 400, it is a leap year. The first instance when the third criterion was used in most parts of the world was the year 2000. You can find more information here:
