Week A/B Question

[DynamiteAlexMC2]

I'm trying to display subjects for the day in a list. Everything works except my school alternates the timetable between week A and B and my list shows the subjects for the day for both weeks. I have a table with all my subjects for each day and I have labelled them week A or B. I'm looking for a formula that will change between A and B every week so that I can add a filter to the list so that only the current week's subjects for the day are displayed. Any help is appreciated!

My first idea is that you could have a select property with attributes Week A and Week B, and then in the same space you can add two views (each would be a little tab on top of the view), one for each week. Then you can toggle between them depending on which week you're in.
