The ancients told the time of day by observing the shadow cast by the sun in a sundial, or by an obelisk, like the egyptians. At night, they could determine the time by looking at the position and phase of the moon. Egyptians are responsible for our modern clock around 4000 years ago they divided day and night into 12 parts each, ergo the 24 hours and am and pm.
