Why are weeks 7 days? Why do we have five weekdays and then two days for the weekend?
I understand there is a religious backstory...but are there any other causes for this structure?
It was associated with the seven heavenly bodies; the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. For this reason, some believe, marking rituals every seventh-day became important. A seven-day week based on these same celestial bodies was adopted as far away as Japan and ancient China.
It seems like a stupid but actually quite important question. Who is to say that we would not all be happier and more efficient people if we worked 3 days, took a one day break, and then worked another 3 days.
Or what if weeks were 30 days long?
Or 4 days long?
Like why 7?
Are companies more productive (output) when their employees work like this? Who makes more money because of this structure?
I feel like we are missing some sort of necessary logical explanation here.
If not, has anyone ever experimented on this? Would it make a difference?
Curious your thoughts.
