The leap year algorithm. The three conditions to check in order to know whether a year is a leap or a common one:

Every year that is evenly divisible by 4 is a leap year, unless they are evenly divisible by 100, in which case they also need to be evenly divisible by 400.

1) A leap year can be evenly divided by 4:

1732 is evenly divided by 4.

2) Except if it can be evenly divided by 100 then it isn't a leap year:

1732 is not evenly divided by 100.

3) Except if it can be evenly divided by 400, then it's a leap year:

1732 is not evenly divided by 400.

1732 is a leap year. What is a leap year?

The leap year algorithm. The three conditions to check in order to know whether a year is a leap or a common one:

1) A leap year can be evenly divided by 4

2) Except if it can be evenly divided by 100 then it isn't a leap year

3) Except if it can be evenly divided by 400, then it's a leap year

Every year that is evenly divisible by 4 is a leap year, except for years that are evenly divisible by 100, but these years are leap years if they are evenly divisible by 400:

Examples of leap years.

Leap years multiples of 4 but not of 100 nor of 400: 1992, 1996, 2004, 2008, 2012, 2016, 2020, 2024, 2028;

Common years (NOT LEAP YEARS) multiples of 100, but not of 400: 1700, 1800, 1900, 2100, 2200, 2300;
