What defines a minute? and i dont mean 60 seconds.?
I’m trying to figure out what constitutes a minute, how was the first minute determined? i know that someone did not just count to 60 and say “that’s a minute”. does anyone know where i could find resources on this topic? or could provide me with a starting point?
thanks so much

Here’s a pretty good NON-WIKIPEDIA article:

The Earth turns on its polar axis through fifteen minutes of arc in every minute of time. A minute of arc at the Earth’s equator is approximately a nautical mile.
So determination of the time units is based on Earth’s rotation.
Here’s a detailed article for you.

1/60th of an hour.
try searching for the definition of a “minute” in astronomy… like the distance that light travels… or try wikipedia!
