Possible operators for date fields cannot achieve what you would like to have. You can only select from a specific date to another one or within n days (weeks or months).
With specific dates you would have to change the report each week.
With n days you would not get the week days as you.
Creating a custom function for function operator might help. Right now I don’t remember how it exactly works. But I think you might be able to pass where clause parameters this way.
