    Hi Anonymous,

     

    If you can't ensure which date column with be the small one, you should add some operation to get the specificity one.

     

    As I write above, min and max function can used to auto return the matched date.

     

    I build a sample table with random date store in date1 and date2, then I can use above formula to get the diff between these date column.

     

    Table formula:

    Sample = ADDCOLUMNS(GENERATESERIES(1,100,1),"Date1",RANDBETWEEN(DATE(2015,1,1),TODAY()),"Date2",RANDBETWEEN(DATE(2015,1,1),TODAY()))

     

    Calculate column:

    Diff = DATEDIFF(MIN([Date1],[Date2]),MAX([Date1],[Date2]),DAY)

     

     

    Reuslt:

This seems like it's a usable solution - however I noticed that in some cases I have a start date greater than an end date in some of the rows.  Is there away to accommodate this in the DAX statement so that it will identify these rows and simply "error" but show results where it will work - like in the paste from excel below?

 

 

 

 

Thanks!

Hi Anonymous,


If you can ensure which date column stored the min date value, you can direct use datediff function without other functions.

Calculated column: datediff(mindate, maxdate, unit)

Day Count = DATEDIFF([Min Date Column],[Max Date column],DAY)

 Did you test in excel? If this is a case, you can try to use column index calculate. (for e.g. DATEDIF(A2,B2,"D"))

 

DATEDIF function
