>>88374395Honestly if I had to guess, it probably comes from of one of the groups between the Theopetran & early Mesopotamian civilizations. So somewhere between 23 and 10 thousand years ago when people first started to organize themselves and sort out enough food to have jobs not focused on direct survival
Somewhere around there some dude would have been thinking that it would be easier to deal with all the other people he interacts with by scheduling things out several days in advance, this then got passed on and recreated thousands of times up to the present day where it's the standard for anyone with an actual career of any kind
If you meant 7 days specifically though you're probably looking at the Babylonian governments or a precursor to them, so only around 4 thousand years ago
