I need a T-SQL solution to find out how many weeks have passed between 2 dates.
The week starts on a Monday and ends on a Friday.
So if the date was this Thursday and the new date is next Monday I need the answer to be 1.
In other words I do not need to be counting full weeks. This is necessary to change dates in multiple weeks of a project when a target date changes.
So if the target date is Thursday 2018/12/06 and it's changed to Tuesday 2018/12/18 my answer would be 2. (remember I do not count full weeks). Each instance passed a Monday is considered a week. And I need it to start changing (adding the weeks) with the current weeks Monday. So if today was Tuesday 11/27/2018 these would be my old dates and new dates. (There are dates before the target date and after the target date).
Original dates. New dates
M-12/03/18:F-12/07/18 M-12/17/18:F-12/21/18 Target date
