It was a tiny bit of time. It was not like our clocks. People used the sun to tell time. They watched shadows move on a dial.

One hour could have many moments. The sun changed how long an hour lasted. This happened as the seasons changed. A moment was about 90 seconds long. It was used before mechanical clocks. It is fun to think about old time.
