Count number of Days In current Month

Hello,

 

I need a measure to count the number of days in the current month, without the use of any tables etc. 

it should show whether this month has either 30, 31, 28 or 29 days. I want to use this number to calculate daily target from a fixed taraget value. 

 

Thank You!

HI @Anonymous

 

You could try

 

Measure 2 = 
VAR t = TODAY()
RETURN  
    COUNTROWS(
        CALENDAR(
            FORMAT(t,"YYYY-MM-01") ,
            EDATE(FORMAT(t,"YYYY-MM-01"),1)-1
           )
    )

or

 

Measure 2 = 
VAR s = FORMAT(TODAY(),"YYYY-MM-01")
VAR e = EDATE(FORMAT(TODAY(),"YYYY-MM-01"),1)
RETURN int( e-s)

Hi @powerbiuser32

 

Try this measure:

Days_current_month =
DAY (
    IF (
        MONTH ( TODAY () ) = 12;
        DATE ( YEAR ( TODAY () ) + 1; 1; 1 );
        DATE ( YEAR ( TODAY () ); MONTH ( TODAY () ) + 1; 1 )
    )
        - 1
)

Regards.

Hi @Anonymous

 

Thank you. However the code returns a syntax error when copied an pasted.

@powerbiuser32,

 

The code works, surely what is happening is that you have Power BI Desktop configured to use commas instead of semicolons as DAX separators, and for this reason @Phil_Seamark's code worked without problems (using commas). So you should simply change the semicolons by commas.

Here you have a tool to detect syntax errors in DAX and format with a recommended indentation, you can modify the separators in US / UK (comma) and Others (semicolon):
