    Ruksuro,

     

    You may refer to the following DAX that creates a new table.

    Table =
ADDCOLUMNS (
    CALENDARAUTO (),
    "Count", CALCULATE (
        DISTINCTCOUNT ( Table1[Customer ID] ),
        FILTER (
            Table1,
            Table1[Subscribed From] <= [Date]
                && (
                    Table1[Subscribed Until] > [Date]
                        || ISBLANK ( Table1[Subscribed Until] )
                )
        )
    )
)

Thanks for this v-chuncz-msft, worked perfectly.

 

Just for everyone else's information, this solution is not fast (given it's having to count each row multiple times it's not surprising). For a large dataset you might want this info precalculated at source.

 

Very impressed with DAX so far!
