**In the Gregorian calendar 3 criteria must be taken intoaccount to identify leap years:**

- The
**year**is evenly divisible by 4; - If the
**year**can be evenly divided by 100, it is NOT a**leap year**, unless; - The
**year**is also evenly divisible by 400. Then it is a**leap year**.

Also to know is, how do you calculate the number of leap years?

To **calculate** whether or not a **year** is a**leap year**, start by checking if the **number** is evenlydivisible by 4 since **leap years** need to be. Then, if it isevenly divisible by 4, check to see if it's evenly divisible by100. If it's not, then it's a **leap year**.

Also Know, how many leap years are there in 2 years? So 2000 and 2400 are **leap years** but 1800, 1900,2100, 2200 and 2300 are not. Apart from that, every **year**divisible by 4 (2012, 2016, 2020, 2024, etc.) is a **leapyear**.
