## Why Do We Have Leap Years?

We have leap years because the earth’s orbit around the sun is 365.24 days long. To make up for the inexact number, we add an extra day, February 29th, to the calendar every four years.

## Evaluation of Leap Year

Leap year is an extra day that is added to the calendar every four years to make up for the lost time caused by the earth’s orbit around the sun. The Gregorian calendar, which is the most commonly used calendar today, is based on the earth’s orbit around the sun. A year on the Gregorian calendar is 365 days long, but the earth’s orbit around the sun is actually 365.24 days long. This means that the Gregorian calendar loses about 1/4 of a day every year, or about 1 day every 4 years. To make up for this lost time, an extra day, or leap day, is added to the calendar every 4 years.

### How to Determine Whether Any Year is a Leap Year?

• To determine whether a year is a leap year, divide it by 4. If the result is a whole number, the year is a leap year. If the result is not a whole number, the year is not a leap year. For example, the year 2020 is a leap year because it is divisible by 4. The year 2020 is not a leap year because it is not divisible by 4.
• A leap year is a year with an extra day, February 29th, in order to keep the calendar aligned with the astronomical year. To determine if a year is a leap year, you can use a simple algorithm that checks if the year is evenly divisible by 4. If it is, then the year is a leap year.
• For example, the year 2019 is a leap year because it is evenly divisible by 4. The year 2018 is not a leap year because it is not evenly divisible by 4.
