I am trying to skip weekends from a date in a spreadsheet,

In Cell A1 I have todays date

In cell A2 A3 A4 A5 I need it to be the previous days date so based on
todays date
A2 would be 12-17, A3 tho would have to be 12-14, A4 would have to be 12-13
and so on

tomorrow tho

A2 would be 12-18 A3 would be 12-17 A4 should be 12-14 ...

what is the easiest way to accomplish this

thanks in advance
