Days between two dates and a date slicer

[Farmertree]

I would like to count a total number of available days between a variable range of two dates defined by a slicer. I have a table with employees ID, start date and end date. Missing end dates indicate employees are still employed.

In my report I would like to have a card visual that shows the sum of days that employees are available between a date range defined by a slicer. Something like this:

Is it possible to create such a measure?

Thank you for your help!

Hi @Farmertree ,

Yes, it is possible. You can add variables to extract min and max date from selected calendar date and compare with start/end date to get datediff. After these, package them with a sumx function to summary datediff result.

Meausre =
VAR selected =
    ALLSELECTED ( Calendar[Date] )
VAR _max =
    MAXX ( selected, [Date] )
VAR _min =
    MINX ( selected, [Date] )
RETURN
    SUMX (
        ADDCOLUMNS (
            ALLSELECTED ( Table ),
            "Diff", DATEDIFF ( MAX ( [Start date], _min ), MIN ( [End date], _max ), DAY )
        ),
        [Diff]
    )

@Anonymous Thanks! This helps a lot. The only problem is that this formula returns a negative DATEDIFF value for End dates < _min. Do you know how i could apply a filter within this formula that only selects rows in which Enddate >= _min?

HI @Farmertree ,

You can do compare between date and _min to get the bigger one and use in datediff function:

Measure =
VAR selected =
    ALLSELECTED ( Calendar[Date] )
VAR _max =
    MAXX ( selected, [Date] )
VAR _min =
    MINX ( selected, [Date] )
RETURN
    SUMX (
        ADDCOLUMNS (
            ALLSELECTED ( Table ),
            "Diff", DATEDIFF (
                MAX ( [Start date], _min ),
                MIN ( MAX ( [End date], _min ), _max ),
                DAY
            )
        ),
        [Diff]
    )
