    = Date.StartOfWeek(Date.From(DateTime.LocalNow())) - #duration(2,0,0,0)

      CNENFRNL  thanks but not what I wanted.

       

      This is giving me date of 2 days ago i.e. 24/07/2021 which was Saturday.  Can it be dynamic to calculate from any date what was last Friday date? 


      Thanks

        And here is another way.

         

        = List.Max(List.Select(List.Dates(Date.AddDays([Date], -6),7,#duration(1,0,0,0)), each Date.DayOfWeek(_) = 5))

    Here is one way to do it in a custom column.

     

    = if Date.DayOfWeek([Date]) >= 5 then Date.AddDays(Date.StartOfWeek([Date]), 5) else Date.AddDays(Date.StartOfWeek([Date]), -2)
