Germany switched to starting Monday in 1969/1976. Before, since the middle age, it had been practice to start the week on Sunday. However, I don't know why this was changed.

Traditionally, the seventh, "no-work", day is Sabbat, which happens to be on Saturday.

Wouldn't the day God rested have been the first full day humanity existed, and so the first day of the week (and of all time). I don't really use a particular day to start my week personally, I keep my calendars in day by day mode.

Starting on Monday is a recent work based change in western countries who previously did sunday.

Yeah seriously, this annoys me so much, that I changed the calendars on my phone and PC to start the week on Monday. It simply makes more sense.

I prefer to start my weeks on Friday night. Get my personal stuff out of the way and prepare for the week ahead low pressure.

Week starts with church day, as God intended!

(I don't actually know the reason, but I wouldn't be surprised if that's the reasoning for the Gregorian calendar)
