What is the best way to retrieve the dates for last Monday and Friday

Question

I need to get the dates for Monday and Friday last week. To do this, i am getting the date of Monday this week and subtracting 7 days. This gives me the date for Monday last

Answer 1

The only thing I see wrong is that you are in fact testing the range Mo-Fr, and not, as stated, retrieving two specific days. It would be safer to test range Mo-Sa with exclusive upper bound.
