Last Friday date

Hi,

 

How can I get last Friday date in a Custom Column of Power Query please?

 

Today is 28/07/2021 so last Friday date was 23/07/2021.

 

Thanks

Found a solution on Desktop forum:

Date.AddDays(Date.From(DateTime.LocalNow()),-Date.DayOfWeek(Date.From(DateTime.LocalNow()),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)

= 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))
