What Is a Leap Year?

A leap year has 366 days instead of the usual 365 days, and occurs nearly every four years. The extra day during leap years is leap day on February 29

Is 2020 a Leap Year?

Yes, the next leap day is February 29, 2020.
The previous leap day was February 29, 2016.

How to Calculate Leap Years

In the Gregorian calendar, three criteria must be taken into account to identify leap years:
  • The year can be evenly divided 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.
According to these rules, the years 2000 and 2400 are leap years, while 1800, 1900210022002300 and 2500 are NOT leap years.

Special Leap Year 2000

The year 2000 was somewhat unique as it was the first instance when the third criterion was used in most parts of the world since the start of the transition from the Julian calendar to the Gregorian in 1582.
