# Who was the first person to arbitrarily define what a second is, and count 60 seconds to make a minute and then 60 minutes to make an hour?

and realize there are 24 of these "hours" in a single day and start living by this time

Sumerian....the 1st first civilization. It was based on their 1000 year observations of what rotating earth is...a ball imbedded among the constantly rotating cosmos around it. In the irrigated semi desert bountiful farms, early civilization in the always cloudless skies and pure dark without electricity allowed every day such observations.

They could 'count' as they lay in the night desert breezes after their day farm work for 1000 years...They found the planets rotation could be used as a unfailing clock' to count their own human lives. And the number 60...because 'even numbers' are useful because they can be endlessly divided and multiplied., plus the highest count easy on a clay tablet.

Not only that...60 minutes per hour per 24 hour day x 364 days per year was the...only...EXACT...number to count the time of the earths repeating journey round the Sun...Other numbers do not work out to mark when 'we' (earth) were last 'here' in the sky till we start out again on the always repeating cycle.

I guess in a perfect clear cloudless night for 1000-3000 years watching because it was there, and you couldn't help it 1 billion stars....humans learned to count in addition to our fingers and toes and do simple and even cosmic math.

The Babylonians used a Base 60 (or sexagesimal) counting system, which they inherited from the Sumerians, dating back to more than 2,000 BC. This is a handy mathematical model for fractions as well, since 60 is the smallest number divisible by the first 6 numbers (1,2,3,4,5,6) as well as 10, 12, 15, 20 and 30.

An Actual day is 23 hours and 56 minutes   this accounts for being a day short, every 4 years  which is why we have a leap day...so he didn't quite get it right who ever it was

They started with the day, which was one rotation of the earth, and worked back from there.  Not aware of any one person who took credit for that.

That was Father Time. He was OCD and had to have more order in his life.
