How did people tell time at night before clocks? - Lemmy.World

The sun dial worked during daylight, but how did people agree on what time it was at night before clocks were invented?

some towns hired people to wake the town for work, and someone else would be hired to wake them up. some societies studied the stars and moon to tell the time at night. and like others stated, there were candles, lanterns, and furnaces to tell how much time has passed. people were more in tune with their environment
How did the wakeyuppymen know what time to start wakeyuppying, tho?
He gets woken up by the wakeyuppy-wakeyupperer.
