Hi all I have the below calculation for fiscal week numbers, however it start the fiscal canlendar to start on the 1st April each year and I need it to start on the 1st Monday in April each year. 

 

Can anyone suggest how to change this to get the right outcome? 

Fiscal Week = 
--Inputs--
VAR WeekStartsOn = "mon"
VAR FiscalStartMonth = 4

--Calculation--
VAR FiscalFirstDay = 
    IF(
        MONTH('Date Table'[Date]) < FiscalStartMonth,
        DATE(
            YEAR('Date Table'[Date])-1,
            FiscalStartMonth,
            1
        ),
        DATE(
            YEAR('Date Table'[Date]),
            FiscalStartMonth,
            1
        )
    )
VAR FilteredTableCount = 
    COUNTROWS(
        FILTER(
            SELECTCOLUMNS(
                GENERATESERIES(
                    FiscalFirstDay,
                    'Date Table'[Date]
                ),
                "Dates",
                [Value]
            ),
        FORMAT([Dates],"ddd") = WeekStartsOn
        )
    )
VAR WeekNos = 
    IF(
        FORMAT(FiscalFirstDay,"ddd") <> WeekStartsOn,
        FilteredTableCount + 1,
        FilteredTableCount
    )
RETURN
    "Week " & WeekNos

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

 

 

Hi, 

 

Thanks for this, 1 small issue it's showing the first dayte as zero and I'm now a day behind in the calculation is there a way to fix this? it might be something I've done.

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.

@billyrich83 , Try these new columns

 

Start Of year = if(month([Date]) <4, date(year([Date])-1,4,1), date(year([Date])-1,4,1))


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

 

FY Start of Week = minx(filter('Date', [Start of Week] >= [Start Of year]), [Start of Week])

 

FY Week No = quotient(datediff([FY Start of Week], [Date], day),7) +1
