Filtering Data from the previous x weeks (Monday to Sunday)

Hi All,


When I filter the number of previous weeks in Query, Power BI takes one week as Sunday to Saturday. Is there a way for me to set or change it so that Power BI reads one week as Monday to Sunday? Thanks in advance for the help


Best Regards

Hi @7ea8ea ,


You can create a column by WEEKNUM:

WEEKNUM = WEEKNUM('Table'[Date],2)

 Week begins on Monday. Weekdays are numbered 1 through 7.


And you can use measure like below to filter the number of previous weeks.


Measure = CALCULATE(SUM('Table'[column]),FILTER('Table','Table'[WEEKNUM] = WEEKNUM(Today())- selectednumber)))


If this post helps, then please consider Accept it as the solution to help the other members find it more quickly.

@7ea8ea , Create a date table with Week columns like these

New columns

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)	


New measures

This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
