How Did the First Clocks Come to Be Invented?

Long ago, people used the sun to tell time. But when it got dark or cloudy, they couldn’t see it anymore. So someone thought, What if we could count seconds like a heartbeat? That’s how the first clocks came to be invented, by using gears and weights that moved in a steady rhythm.

Clocks use gears inside them to keep time moving forward. Like when you turn a doorknob, it moves smoothly because of little wheels inside. Early clocks worked the same way, big wheels made from wood or metal turned slowly, and every full turn meant an hour had passed.

The first real clock was built in a monastery in Italy around 1300 AD. It looked like a tower with big hands that people could see from far away. These clocks helped monks keep track of their prayers all day long, even when it got dark.
