In the Abrahamic tradition God created the world on Sunday, then rested on the seventh day, the Sabbath, which is observed in the Jewish faith. I think the Romans borrowed the seven day week from the Egyptians who also had a “Sun day” as their first day of the week. The Christians moved to resting on Sunday instead of Saturday around the fourth century probably because of Easter Sunday. In some Muslim countries Friday and Saturday is the weekend.
Are we sufficiently off topic?
