Also, don't forget days of the week are also of very Pagan.
This is the reason the Hebrews always called them by their number....and not by their common name. Sabbath, of course, means seventh. When they wanted to refer to Monday, i.e. they would say, "The second day"....etc. This was also done by the Apostles and the Early Church. They never referred to the days of the week by their pagan names.
