It takes 24 hours for the Earth to turn all the way around (rotation). That makes one day and one night.
At any moment, half of the world is in daytime and half is in nighttime.
The world is like a ball. We call the top half the Northern hemisphere and the bottom half the Southern hemisphere. The (imaginary) line between them is called the equator.
Explanation:
Daytime is when you can see the sun from where you are, and its light and heat can reach you. Nighttime is when the sun is on the other side of the Earth from you, and its light and heat don’t get to you.
We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it.
It takes 24 hours for the world to turn all the way around, and we call this a day. Over a year, the length of the daytime in the part of the Earth where you live changes. Days are longer in the summer and shorter in the winter.
