What is 24 hours?

A day is like a clock that takes one full spin around the Earth, and 24 hours is how long it takes for that whole trip to finish.

An hour is like counting from 1 to 60, but you do it twice. First, you count up to 60 seconds (like a short song), and then you repeat that, 60 times! That makes one full hour. You can think of your favorite cartoon: when it starts at 3 o'clock and ends at 4, that’s one hour of fun.

Now imagine you have 24 of those fun hours in a row, like having 24 cartoons back-to-back with no breaks! That whole time is called a full day. From when the sun comes up in the morning to when it goes down and hides behind the hills at night, that’s one day, and that takes exactly 24 hours.
