What was the previous leap year?

The most recent leap year was in 2012. The next leap year is in 2016.

You can tell if a year is a leap year using the following rule. The year is evenly divisible by 4. An except is if the year is also evenly divisible by 100 and not evenly divisible by 400. For example, the year 1900 is evenly divisible by 4 and 100 but not divisible by 400 so it was not a leap year. The year 2000 is evenly divisible by 4, 100, and 400 so it was a leap year.
