History/Background

The concept of hours has been in use since ancient civilizations. The Babylonians used a sexagesimal (base-60) system around 1500 BCE, which included the division of the circle into 360 degrees and the hour as 1/24 of the day.

Evolution of Timekeeping

The ancient Greeks used sundials to measure time, while the Romans developed water clocks (clepsydras) in the 1st century BCE. The invention of mechanical clocks in the Middle Ages allowed for more accurate timekeeping.
