Calculating number of days between two dates

Hi,

 

I have two dates columns and I want to calculate the number of working days between those two dates? like network days in excel.

How can we do this here in power BI?

 

Thanks.

Assume you have a dataset as below. We can create a calendar table and add a column in it to mark the working days. Then create a column in NetWorkDays table to show the number of working days.

  1. Create a calendar table and add a column. Create a 1:1 relationship between DimDate(Date) and Holidays(Date).
    DimDate = 
    CALENDAR ( MIN ( NetWorkDays[Start date] ), MAX ( NetWorkDays[End date] ) )
    
    WorkingDay_Mark = 
    VAR WeekDayNum =
        WEEKDAY ( DimDate[Date] )
    RETURN
        (
            IF (
                OR (
                    OR ( WeekDayNum = 1, WeekDayNum = 7 ),
                    RELATED ( Holidays[Date] ) <> BLANK ()
                ),
                FALSE (),
                TRUE ()
            )
    )

  2. Create a column in NetWorkDays table.
    WorkingDay_Num = 
    COUNTROWS (
        FILTER (
            DimDate,
            AND (
                AND (
                    DimDate[Date] >= NetWorkDays[Start date],
                    DimDate[Date] <= NetWorkDays[End date]
                ),
                DimDate[WorkingDay_Mark]
            )
        )
    )

Please have alook at this, it may answer your question:

 

http://www.powerpivotpro.com/2012/11/networkdays-equivalent-in-powerpivot/

 

Can you try something like:

=CALCULATE(SUM(Dates[IsWorkday]),
           DATESBETWEEN(Dates[Date], 
                        TwoDates[Column1],
                        TwoDates[Column2]                       )
          )

When creating a new column using the below code, this method equates to an #ERROR (see attached screenshot)

 

WorkingDay_Num = 
COUNTROWS (
    FILTER (
        DimDate,
        AND (
            AND (
                DimDate[Date] >= NetWorkDays[Start date],
                DimDate[Date] <= NetWorkDays[End date]
            ),
            DimDate[WorkingDay_Mark]
        )
    )
)

Why doesn't it like these columns? Just because they are not DAX!!??Why doesn't it like these columns?

Were your columns on the 'NetworkDays' table named [Start Date] & [End Date] DAX/Measures?

 

Is there any reason why I can only choose measures?
