alanspazzaliartist:THE SUMERIANSThe Sumerians looked up to the sky as they invented the time system and we still use it today. It may be curious that we divide the hours into 60 minutes and the days into 24 hours, why not a multiple of 10 or 12? In short, the answer is because the inventors of time did not operate on a decimal (base 10) or duodecimal (base 12) system, but on a sexagesimal (base 60) system.For the ancient Sumerian innovators who first divided the movements of the sky into countable intervals, 60 was the perfect number. The number 60 can be divided into 1, 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30 equal parts. Also, ancient astronomers believed that there were 360 days in a year, a number that would fit perfectly into six times. The Sumerian civilization did not last. However, for more than 5,000 years, the world has maintained its commitment to the delimitation of time. de kicsi a feje -- source link
