Hey, kids! Have you ever heard of a leap year?

It’s a year that has an extra day added to it, making it 366 days long instead of the usual 365.

But why do we need an extra day in some years?

The reason is because the Earth actually takes a bit more than 365 days to complete its orbit around the sun. So, without the extra day every four years, our calendar would slowly get out of sync with the seasons.

Leap years happen every four years, except for years that are divisible by 100, but not divisible by 400. So, the year 2000 was a leap year, but the years 1700, 1800, and 1900 were not. This rule makes sure that our calendar stays as accurate as possible.

This year you will see February 29th on the calendar: it’s because 2024 is a leap year!

And now watch a video on leap years and leap days.
