Week Starting on Friday and ending on Thursday

[HarryB]

Hi all,

I want to change my calendar so for some specific weekly calculations my week will start on Friday and end of Thursday.

This is my calendar below.

Which parts will I need to change below?

VAR __RESULT =

    ADDCOLUMNS (

        ADDCOLUMNS (

            __BASE,

            "Year", YEAR ( [Date] ),

            "Month Long", FORMAT ( [Date], "mmmm" ),

            "Month Short", FORMAT ( [Date], "mmm" ),

            "Month Number", MONTH ( [Date] ),

            "Month and Year", FORMAT ( [Date], "mmm-yy" ),

            "YYYYMM", FORMAT ( [Date], "MMM" ),

            "Quarter", "Q" & QUARTER ( [Date] ),

            "Day of Week Long", FORMAT ( [Date], "dddd" ),

            "Day of Week Short", FORMAT ( [Date], "ddd" ),

            "Day Sort", WEEKDAY ( [Date], 1 ),

            "Week of Year", WEEKNUM ( [Date] ),

            "Week Ending Saturday",

                VAR __DAY =

                    WEEKDAY ( [Date] ) - 6

                RETURN

                    [Date] - __DAY,

            "Week Ending Thursday",

                VAR __DAY =

                    WEEKDAY ( [Date] ) - 5

                RETURN

                    [Date] - __DAY

        ),

        "Week Starting Thursday", [Week Ending Thursday] - 6

    )

RETURN

    __RESULT

Hello @HarryB,

Can you please try the following approach:

VAR __RESULT =
    ADDCOLUMNS (
        ADDCOLUMNS (
            __BASE,
            "Year", YEAR ( [Date] ),
            "Month Long", FORMAT ( [Date], "mmmm" ),
            "Month Short", FORMAT ( [Date], "mmm" ),
            "Month Number", MONTH ( [Date] ),
            "Month and Year", FORMAT ( [Date], "mmm-yy" ),
            "YYYYMM", FORMAT ( [Date], "MMM" ),
            "Quarter", "Q" & QUARTER ( [Date] ),
            "Day of Week Long", FORMAT ( [Date], "dddd" ),
            "Day of Week Short", FORMAT ( [Date], "ddd" ),
            "Day Sort", WEEKDAY ( [Date], 1 ),
            "Week of Year", WEEKNUM ( [Date], 2 ),
            "Week Ending Thursday",
                VAR __DAY =
                    WEEKDAY ( [Date], 2 ) - 7
                RETURN
                    [Date] - __DAY,
            "Week Starting Friday", 
                VAR __DAY = 
                    WEEKDAY ( [Date], 2 )
                RETURN
                    [Date] - __DAY + (7 - __DAY) % 7
        ),
        "Week Starting Thursday", [Week Ending Thursday] - 6
    )
RETURN
    __RESULT
