Long ago, people didn't have clocks! โณ
Instead, they watched the sun move across the sky. They noticed that the sun takes about 12 hours to rise and set. Ancient Egyptians created the first sundials, which divided the day into 12 parts. Later, in the 14th century, mechanical clocks were invented, and people began to divide hours into smaller parts, including minutes! ๐ฐ
