If it were an even number those body builders wouldn’t have had to argue over it
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!
Eh, that doesn’t really answer it. Months are about 30 days long. First, there are better numbers than 7 to fit in 30. Five 6 says weeks would work much better for this. Second, moon “phases” are completely arbitrary. Really there are only two “phases”, waxing and waning; anything else is arbitrary subdivisions.
The real reason there are seven days in the week is because there are seven moving objects in the sky. (From a human perspective.) There are seven days of the week:
- The Day of the Sun
- The Day of the Moon
- The Day of Mars
- The Day of Mercury
- The Day of Jupiter
- The Day of Venus
- The Day of Saturn
These are the seven days of the week. They’re named for the seven great moving lights in the heavens. Everything else is a fixed star or invisible to human eyes.
Wasn’t (Julius) Caesar and some other dude responsibles for adding 2 months to the year (Augustus I guess) ?
It’s 29.5 days for the moon cycle, not 28.
Pretty sure it was religion, rest on the seventh day.
Babylonians divided their lunar months into 4 weeks, the number seven was significant as the number of celestial bodies they could see other than non-moving stars. It wasn’t until later that the seventh day got any association with resting.
I read about it in a few places it this sums it up: https://www.scienceabc.com/eyeopeners/why-do-we-have-seven-days-in-a-week
That whole article is reaching. Like holy cow. “7 celestial bodies, therefore!!1!” I forget the proper name of it, but it’s backwards looking. The lunar cycle holds a little bit, but they could have broken 29.6 days into any number of parts for any reason.
It’s because 7 days of work (6 days 1 day off) is the maximum we can work, and then we wrote it backwards into religion and everything else.
That’s not the best source necessarily but I read a few, maybe they did have the 6 and 1 days because of our working ability, but to say that would be an assumption whereas there are records about the reasoning of the seven days being based on the primary celestial objects in our sky. Why do you assume that’s the maximum we can work? Plenty of people have worked more or less in different societies or careers.
Eh, don’t forget that Julius and Augustus Caesar made months for themselves (July and August). Or is that made up? I’m not really sure. It’s an interesting story though. But Sept- means seven, Oct- means eight, Nov- means nine, and Dec- means ten, so it stands to reason that July and August were disruptively added somehow.
The Roman calendar originally didn’t last all year round. It began in the spring and ended at the start of winter, and then the winter period just didn’t exist on the calendar.
Calendars were invented to plan the growing of crops, so tracking the days in winter didn’t have any purpose, so they left winter out.
That’s also why the months are numbered wrong. If you know Latin, or at least one of the romance languages that derived from Latin, then "Septem"ber should be the 7th month, "Octo"ber should be the 8th month, "Novem"ber should be the ninth month, and "Decem"ber should be the 10th month. But that’s not how it works today, as we no longer count March as the first month of the year.
All because of religion: rested in the seventh day.
I think 6 day weeks would be ideal (4 days work 2 days off).
The French had 10-day weeks for a while.
Metric Week 💚
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.
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
Weeks are made up. Like hours and minutes.
No shit.
Which is why we should stop believing minutes and hours and weeks are real
