Calculate Week Number

[Preetsingh86]

Hi, I am trying to calculate financial week number for the dates column. Our financial year starts from Sept - Aug, and our first day of work is Sunday. I have tried DAX measure WEEKNUM but not sure what returntype will be and then I presume I have to add additional formula to ensure my week starts from sunday

Any help will be great

Thank You

@Preetsingh86 Hi! Try to adapt this new calculated column to your data:

Financial Year =
IF(
MONTH([Date]) >= 9,
YEAR([Date]),
YEAR([Date]) - 1
)

Financial Week Number =
VAR StartOfYear =
DATE([Financial Year], 9, 1)

VAR WeekNumber =
WEEKNUM([Date] - StartOfYear + 1, 11)
RETURN
WeekNumber
