## In a leap year there are 31,622,400 seconds.

## How many seconds are in a leap year?

## How many seconds is 1 leap year – Steps

So, . 1 minute = 60 seconds . 1 hour = 60 minutes 1 hour = 60s x 60m = 3,600 seconds(PS: minute= m, second= s,hour= h, day= d, year= y)Then, . 1 day = 24 hours . 1 leap year = 366 days a leap year = 3,600s x24h x 366d = 31,622,400 secondsa leap year = 31,622,400 seconds |

### Watch the following videos to learn more about leap years, like:

: it is an effort made by us to synchronize the fixed calendar and the revolution of the earth around the sun. (And it’s possible to see**Why do we have leap years?****lunar eclipses**when the shadow of this revolution covers the moon.)

So you can know if it’s a leap year or not:**How to calculate a leap year?**

**Tip 1,** check the length of the second month – February, when there are 29 days in February, then it is a leap year.

**Tip 2,** And every other four years is a leap year, so if the year can be **fully divided by 4** (except century years by 400), there you have a leap year.

For instance, the year of 2023, 2023 ÷ 4 = 505.75 （it’s a common year).

2024÷ 4 = 506, so 2024 is a leap year.

The year of 2000 is the end of a century, 2000÷ 400 =5, so it’s a leap year. The year of 2100, we have 2100÷ 4 =5.25, not a leap year.
