In the Middle Ages, timekeeping methods were primarily based on the position of the sun in the sky. Sundials were commonly used to track time during the day, with the shadow cast by the sun indicating the time.

Candle clocks were another method, where time was measured by the amount of wax that had burned. These methods were imprecise compared to modern timekeeping but were sufficient for daily activities in the Middle Ages. **
