Detailed explanation-1: -The number of seconds in a minute-and minutes in an hour-comes from the base-60 numeral system of ancient Mesopotamia. Developed around 3100 B.C., the sexagesimal system, as it is known, has fallen out of favor but is still used (with slight adjustments) to measure time and angles.
Detailed explanation-2: -THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Detailed explanation-3: -The Sumerians divided night and day into 12 equal hours each, whose length varied with the seasons as the length of the daylight hours changed. They also divided the astronomical day, our 24 hours, into 12 equal hours, and each hour into 30 smaller units, making for 360 of these smaller units for each day.
