Who decided on these time divisions? 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.
Why is minute in an hour called minute?
Historically, the word “minute” comes from the Latin pars minuta prima, meaning “first small part”. This division of the hour can be further refined with a “second small part” (Latin: pars minuta secunda), and this is where the word “second” comes from.
What if a minute was 100 seconds?
Now, according to your question, if 100 seconds would make 1 minute, then a day would be made of 86400/100= 864 minutes and if 100 minutes would make 1 hour, then a day would be made of 864/100=8.64 hours.

Why did they start keeping minutes and seconds?
Minutes and seconds were but hypothetical quantities of time. According to David S. Landes, in “ Revolution in Time ” (Belknap, 1983), astronomers of the 16th century began physically realizing minutes and seconds with the construction of improved clocks with minute and second hands in order to improve measurements of the sky.

Why are there 12 hours in a night?
However, each twilight period had 3 of these decans assigned, leaving 12 for the period of complete darkness (the duodecimal system is working here as well!). Thus, the rise of each decan marked an hour, so we ended up with 12 hours in each night. However, at that time, the hours did not have a fixed length.
