Answer 2

In earlier days, people use to measure time on the basis of the occurrence of periodic events in nature.

How was time measured in the past?

• The sundial was developed by the Greeks and furthered by the Romans a few centuries later (it is, of course, only useful while the sun is shining).
• In order to measure time even when the sun was not shining, at night, or on cloudy days, the Romans also utilized water clocks that they calibrated from a sundial.

How can we gauge time in the past?

• Before 1500 B.C., the Egyptians developed sundials, which marked the beginning of timekeeping.
• The time the Egyptians kept track of, however, was different from the time that modern clocks keep track of.
• The duration of daylight served as the fundamental measure of time for the Egyptians and, in fact, for another three millennia.
