2-2-3 Shift Matrix

[Locc]

I currently have data that I need to break down by shift.

We have 4 shifts, A,B,C,D. A/B are day shifts, and C/D are night shifts. A/C shifts work together days/nights and B/D work together days/nights. We are on a 2-2-3 schedule and Jan. 1 this year was an A/C day. Shifts run from 7am-7pm and 7pm-7am. 

Is there a query I can use to automatically create a date table, similar to the result from this thread?

I'd like to create a slicer/filter and see data for each shift.

@Locc , I think first you need to create period of 7 week and then further split, Like we have done for 4-4-5
