## How many seconds are in a leap year?

People nowadays use second, minute, hour, day, month and year from the SI Units to measure time, which is clear to everyone in our daily lives.

And there is decade, which stands for a period of 10 years. Then we have century, a period of 100 years. So how long is 1 leap year in seconds?

## How many seconds is 1 leap year – Steps

As we know, there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, 365 days in a year (in this case a year is a common year with exactly 365 days) and 366 days in a leap year (every fourth calendar year is a leap year). So how many seconds are in a leap year exactly? Let’s break it down.

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

• Why do we have leap years? : 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 lunar eclipses when the shadow of this revolution covers the moon.)
• How to calculate a leap year? So you can know if it’s a leap year or not:

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.
