Hi billyrich83 ,
I just modified a little in your code and it worked

Create a new column as below

Start of Week = ('Date'[Date]+-1*WEEKDAY('Date'[Date],2)) + 1

 

Modified the DAX that you shared as follows

FiscalWeek = 
--Inputs--
VAR WeekStartsOn = "mon"
VAR FiscalStartMonth = 4

--Calculation--
VAR FiscalFirstDay = 
    IF(
        MONTH('Date'[Date]) < FiscalStartMonth,
        DATE(
            YEAR('Date'[Date])-1,
            FiscalStartMonth,
            1
        ),
        DATE(
            YEAR('Date'[Date]),
            FiscalStartMonth,
            1
        )
    )
VAR FilteredTableCount = 
    COUNTROWS(
            SELECTCOLUMNS(
                GENERATESERIES(
                    FiscalFirstDay,
                    'Date'[Date]
                ),
                "Dates",
                [Value]
            )
    )
VAR WeekNos = 
            QUOTIENT(FilteredTableCount+1, 7)
RETURN
    "Week " & WeekNos

    When I checked the code, found that the hard coding that you have done works fine for one year (probably because you have hard coded based on that year) while it does not work for the other year. Have been busy since then. Hence unable to look into this further. May be someone else can get to help you with this.
