Calendar Changes

(see also Lunar Cycle Change, Sabbath, Inclusive Time, High Holidays)

As you can see from the picture at the top and bottom of this resource page, when Rome started having a 7 day week, as before it had an 8 day week, the first day of the week was Saturday. Saturday was demoted to the last day by Constantine and made Sunday in honor of his patron god the first day of the week which before this it was the second day of week.
