How Does the Earth's Rotation Affect Time Zones?

The Earth spins like a toy, making different parts of the world face the Sun at different times. That’s why we have time zones, so each place can have its own time based on where it is on the spinning Earth. Imagine the Earth as a giant clock: when one side is in sunlight (daytime), the other is in shadow (nighttime). Time zones help people match their day to the Sun, even if they're far apart.
