How Does Every Calendar Explained in 20 Minutes Work?

Every calendar is just a special kind of counting tool that helps people know when days, weeks, months, and years change, like how you count steps while walking to school.

Imagine you have a big basket with 7 special stones, each one representing a day of the week. Every time you take a stone from the basket, you say its name: Monday, Tuesday, Wednesday… until Sunday. Then you put all the stones back, and that’s how weeks work!

Now imagine you have another bag with 30 or 31 marbles, each one for the days in a month. Some months are longer than others, just like some of your backpacks feel heavier when you pack more toys.

A year is like having 52 full baskets of stones (which makes 52 weeks) plus a few extra marbles, about 365 of them. That’s how we get all the days in one year. Sometimes, there's an extra day, which is called leap day, and that happens every four years because the Earth takes just a little bit longer than 365 days to go around the Sun.

That’s it, a calendar is just a fun way to count time like you count your toys or your steps!
