ELI5: Before alarm clocks, how did people regulate their sleep schedule and wake up at different times?

Let's say a king wanted to have meeting at 7am back in the 1400s. How did people wake up at a precise time to make it to that meeting?

They didn't, because they didn't schedule like that. They would say "an early meeting at daybreak" and then the king would start the meeting at this convenience.
