Things You Don’t Know About Leap Year

I think any readers here reading this post knows what is a leap year, right?

So, ask yourself these 5 questions (Answer in Yes or No):

  1. Is 2000 a leap year?
  2. Is 2100 a leap year?
  3. Is 2200 a leap year?
  4. Is 2300 a leap year?
  5. Is 2400 a leap year?

All Yes? NOOOOOOO!

Answer: 2000 and 2400 are not a leap year, while 2100, 2200 and 2300 are leap year.

However, why 2000 and 2400 are a leap year while 2100, 2200 and 2300 are not?

This is because we are following something called “Gregorian Calendar”. It is created because the original calendar (Julian Calendar) is not accurate. It is suggested by Aloysius Lilius and named after Pope Gregory VIII.

How to Determine if this is a Leap Year

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the years 1600 and 2000 are.

  1. Did you know there was a suggestion by Matt Parker to instead have leap years every 4 years, and no leap year every 128 years? Then, he suggested that because both of these numbers are powers of 2, we should view years in binary.
