DAX formula to show week of the month, not week of the year

[jderekc]

Hi all,

I've been browsing the internet for ways to show the current week of any given month but all I've come across is week number of the year.  Is it possible to show week of the month?  For instance, instead of week 31/32, it would be week 1 of August.  This may pose a problem if weeks carryover from one month to another though.  See my screenshot below for how it currently looks.  Also, my existing DAX query is also below:

DAX formula:

Week = " Week " & WEEKNUM(VendDisplay[DateCreated], 2) & " - " & FORMAT(VendDisplay[DateCreated], "MMMM")

Any help is appreciated as always.  Thanks!

Regards,

Derek

Hi @jderekc,

Try this column:

Week = " Week " & 1 + WEEKNUM ( VendDisplay[DateCreated] ) – WEEKNUM ( STARTOFMONTH ( VendDisplay[DateCreated] ) ) & " - " FORMAT(VendDisplay[DateCreated], "MMM")

If not works, my recomendation is to use a Calendar table linked to VendDisplay[DateCreated], and then change VendDisplay[DateCreated] to Calendar[Date] in this formula.

This is not a DAX! This is magic! Amazing!

Can you please provide the solution here.

You are a genius, @Anonymous!  I did it and now my bar chart returns "Week 1 - Aug", "Week 2 - Aug", et cetera.  I did have to reformat the DAX formula just a little bit because it gave me an issue that completely failed its execution, but it was just a minor tweak.  Thanks so much!

Derek

It was missing an &. I adjusted it below and it worked fantatstic for me. 

Week = "Week" & 1 + WEEKNUM(DateDimension[Date]) - WEEKNUM(STARTOFMONTH(DateDimension[Date])) & " - " & FORMAT(DateDimension[Date], "MMM")
