How Did Ancient Civilizations Measure Time Without Clocks?

Long ago, people didn’t have clocks like we do today. But they still knew when to plant crops and when to go to bed! They used the sun, which moves across the sky every day, and the moon, which changes shape each month. Some even used water in big pots to measure time, it’s called a clepsydra!
