Creating a shift model

[eNzumWe]

I analyse user numbers, and I would like to divide the work day into early (6 am- 2 pm),  late (2 pm- 10 pm) and night shifts (10 pm- 6 am). Creating the night shift is no problem because it runs every weekday from 10pm - 6 am. IIt is difficult for me to create the early and late shift, because they change every week. In calendar week 48 group A has the early shift (6 am- 14 pm) and group B the late shift (2 pm- 10 pm). In calendar week 49 group B has the early shift and group A the late shift and so on.

I would be very grateful for helpful tips!

My Data looks like this (each row is a user):Data

My Conditional Column looks like this:

This is ok but I need to adjust the weekly change from the early and late shift group.

Hard to be specific without source data. But, if you created an hours table like this:

R06_Table = 
VAR __Hours = 
        SELECTCOLUMNS(
            GENERATESERIES(1 , 12 , 1),
            "Hour",
            [Value] & ":00:00 "
        )
VAR __Period = 
    SELECTCOLUMNS(
        { ("AM"),("PM") },
        "AM/PM",
        [Value]
    )
VAR __HoursAMPM = GENERATEALL(__Hours, __Period)
VAR __Final = 
    SELECTCOLUMNS(
        ADDCOLUMNS(
            __HoursAMPM,
            "Time",
            TIMEVALUE([Hour] & [AM/PM])
        ),
        "Time",
        CONVERT(TODAY() & " " & [Time], DATETIME)
    )
RETURN
    __Final

You could create a Shift column like this:

Shift = 
VAR __1stBegin = 9
VAR __2ndBegin = 17
VAR __3rdBegin = 1
VAR __Time = TIMEVALUE('R06_Table'[Time])
VAR __Hour = HOUR(__Time)
RETURN
SWITCH(TRUE(),
    __Hour >= __1stBegin && __Hour < __2ndBegin,"First",
    __Hour >= __2ndBegin || __Hour < __3rdBegin,"Second",
    "Third"
)
