    Jānis,

     

    Create a date table to return the last day of each month.

    Create a date table

    Date = CALENDAR(DATE(2015,1,1),DATE(2017,12,31))

     

    Create a column to get the last day of each month
    LastDay = ENDOFMONTH('Date'[Date])

     

    Create another table
    LastDayofMonth = SUMMARIZE('Date','Date'[LastDay])

     

    Create a column to get average age.
    AverageAge =
    DATEDIFF (
        CALCULATE (
            AVERAGE ( Table2[BirthDate] ),
            FILTER (
                Table2,
                OR (
                    ISBLANK ( Table2[InactiveDate] ),
                    Table2[InactiveDate] > 'LastDayofMonth'[LastDay]
                )
            )
        ),
        'LastDayofMonth'[LastDay],
        YEAR
    )

Thank you, v-caliao-msft!

 

Almost working. I'm still cheking solution (new with DAX).

I found, that I need one more filter - I need to include only active employees, so I need to filter from "Employment Start Date" too, but not sure - is it correct.

 

AverageAge =
DATEDIFF (
    CALCULATE (
        AVERAGE ( Table2[BirthDate] ),

        FILTER (

            Table2, Table2[Employment Start Date] < 'LastDayofMonth'[LastDay]

            ),
        FILTER (
            Table2,
            OR (
                ISBLANK ( Table2[InactiveDate] ),
                Table2[InactiveDate] > 'LastDayofMonth'[LastDay]
            )
        )
    ),
    'LastDayofMonth'[LastDay],
    YEAR
)
