Why Do We Use ‘Time Zones’ Around the World?

Time zones help people all over the world know what time it is in their part of the planet. Imagine if everyone used the same clock, when it's noon for you, it might be midnight somewhere else! Time zones divide the world into parts that follow the sun’s movement. This way, people can have matching times for their daily activities, like going to bed or waking up.
