Detailed explanation1: Five thousand years ago, Sumerians in the TigrisEuphrates valley in today’s Iraq had a calendar that divided the year into 30 day months, divided the day into 12 periods (each corresponding to 2 of our hours), and divided these periods into 30 parts (each like 4 of our minutes).
Detailed explanation2: The theory is that the Sumerian and Babylonians were keen on the number 60 because 60 has many factors, including the first six numbers, one to six, but also 12, 15, 20, 30. This meant dividing by 60 often gives easy fractions.
Detailed explanation3: The Sumerians created a number of innovations that remain important in the world today. They developed the turning wheel, which made the mass production of pottery possible. They developed cuneiform, one of the world’s first writing systems, which helped lay the groundwork for the development of modern writing.
Detailed explanation4: The history of Sumer spans the 5th to 3rd millennia BCE in southern Mesopotamia, and is taken to include the prehistoric Ubaid and Uruk periods. Sumer was the region’s earliest known civilization and ended with the downfall of the Third Dynasty of Ur around 2004 BCE.
