The number of days in a week wasn’t chosen as an arbitrary number, it was chosen because it’s the length of 1 moon phase. 4 phases of the moon is 1 cycle (new moon to new moon), or 1 month (28 days).
The fact that we now have most months with 30 or 31 days is basically a hack to try to line up 12 months to 1 year (1 orbital period of the earth), but that was never going to work!
If it were an even number those body builders wouldn’t have had to argue over it
Its also inconvenient that the number 10 only really has2 and 5 as factors.
Inconvenient how?
The French had 10-day weeks for a while.
yeah I think we should have 6 day weeks although someone pointed out to me 5 day is divisible into the number of days in a year but I can see dropping the size of the week by something close to 15% of 5 starts getting pretty short for a week
Maybe it’s deliberate though - as the week doesn’t divide well it forces weekly rituals.
All because of religion: rested in the seventh day.
I think 6 day weeks would be ideal (4 days work 2 days off).
I have no knowledge of this ; and would argue the 7 days are because they are prime . If not, it would have long ago be broken up into smaller weeks .
7 days is the Goldilocks zone of that unit of time size . 5 is too small and 11 is too long
I was taught that it's a seven day week because of the seven visible 'planets' the ancients saw in the sky.
Sunday = Sol
Monday = Luna
Tuesday =Twe [aka Mercury]
Wednesday = Wodin [aka Jupiter]
Thursday = Thor [aka Mars]
Friday = Friga [aka Venus]
Saturday =Saturn
Weeks are made up. Like hours and minutes.
Very. I do dialysis every Monday Wednesday and Friday but I have to go 2 days off over the weekend. So Monday I always have more fluids to take off.
