Why does the whole world run on a 7-day system per week (with 1 or 2 days of rest)?
Is this really the optimal system for human physiology? I heard the Soviet tried 10 days, but gave up. China doesn’t have Jewish roots and a reason to follow Genesis and the creation myth. We could have 6 or 8 or 9 or 11. Is there a good reason to stick with 7?
