In many languages the days are numbered, e.g. “First day”, “Second day”, …, “Seventh day”. Speakers of those languages have no question about when the week starts.

Notably, the older languages start the week on Sunday. Some of the languages that start the week on Monday can be attributed to mistranslation from the former group. So starting the week on Sunday is historically more correct.
Disclosure: I speak a language that starts the week on Sunday, so I’m biased.









I hate when that happens. Gotta be a manufacturing error. It happens to me all the time with spoons as well, I’m eating with one normally, and then suddenly it turns inside out and can’t grab any soup!
