Another week is either ending or beginning.

How about a mini survey as to whether Sunday is the first day of the week (per calendars) or the last day (per Judeo-Christian Scriptures.) (I think I've asked that question already.)

And----when Genesis was being written (composed), was there already a concept of a "week" of a set amount of days?

Months reflect lunar rising and setting etc.

And what is the origin of the word week?

(You can tell that this was definitely an IUD in these environs.)`

The above should make for interesting coffee-break conversation.
