Hi Youliana,

I managed to bulid following queries:

 

Fora  week which happened exactly 4 weeks ago: 

" =if[Date]>=DateTime.Date(Date.AddDays(Date.StartOfWeek(DateTime.FixedLocalNow(),1),-28)) and [Date]<DateTime.Date(Date.AddDays(Date.StartOfWeek(DateTime.FixedLocalNow(),1),-21)) then "TRUE" else "FALSE" "

 

For dates oldet than 4 weeks ago:

" =if[Date]<=DateTime.Date(Date.AddDays(Date.StartOfWeek(DateTime.FixedLocalNow(),1),-28)) then "TRUE" else "FALSE" "

 

It works but dates are moving within a week.

I would like to make it stacic for a week.

 

Example: This week is W/c 19/03. Today is 20/03 but I would still like to have a True outcome for dates falling in W/c12/02

 

At the moment the first query would show me today, dates from 13/02 to 19/02 Incl.  But I would like to keep it 12/02-18/02 Untill end of this week. So, True would only move to 19/02 once we are in W/c 26/03. Does that make sense?
