Imagine the Earth is a giant clock. As it turns, different parts of the world see the sun at different times, like morning in one place and night in another. That’s why we have time zones! They help us match our daily lives to the position of the sun. When you travel from one country to another, your watch changes because you are now in a new part of this giant clock.
Examples
- Your friend calls you at lunchtime, but it’s midnight where they are.
- School starts in the morning on one side of the world, but it's already evening on the other.
