Hi @Kbrennan856,

You can use below formula to get Week Number from Saturday to Friday.

Calculate column formula:

weeknum =
VAR _calendar =
    FILTER (
        ADDCOLUMNS ( 'Calendar', "WeekDay", WEEKDAY ( [Date], 1 ) ),
        YEAR ( [Date] ) = YEAR ( EARLIER ( [Date] ) )
    )
RETURN
    COUNTROWS (
        FILTER ( _calendar, [Date] <= EARLIER ( [Date] ) && [WeekDay] = 7 )
    )
        + 1

Hi,

You can include one column with weekday_name, then to do the SWITCH function based on the weekday_name. 

I hope it helps you.

Hi @Kbrennan856,

You can do the SWITCH function like below:

Weekday = 
SWITCH(
    TRUE();

    "Saturday"; 0 ;
    "Sunday"; 1 ;
    ...;

    "Friday"; 6 )

I hope it helps you.
