How Did Ancient Peoples Measure Time Without Clocks?

People used the sun, moon, and stars to tell time. When the sun was up, they knew it was day. At night, they saw the moon and stars to know when to sleep. They also made big fires that burned for hours, like a giant hourglass, but with fire instead of sand!

The sun rises in the morning and sets at night. People watched its path across the sky to know what time of day it was.

The moon changes shape every month, so people counted days using how full or empty the moon looked.
