Count Difference between dates broken out by month

[Niiru1]

Is there a way to calculate the difference between two dates but break them out by months?

My table example is:

ID	Date Start	Date End	Duration
123	12/11/2018	16/11/2018	5
123	02/01/2019	07/01/2019	6
1003	03/06/2019	07/08/2019	66

This count works fine for short dates within the same month but I'm hoping to get a month count between the start and end dates?

So I'm hoping to have some sort of breakout/ split to show:

ID	June	July	August
1003	28	31	7

Thanks.

@Niiru1  firstly, you need create a date table, which have no relationship with your fact table. then try this code

DaysCount :=
SUMX (
    Table1,
    VAR sd = Table1[Date Start]
    VAR ed = Table1[Date End]
    RETURN
        CALCULATE (
            COUNT ( 'Calendar'[Date] ),
            KEEPFILTERS ( DATESBETWEEN ( 'Calendar'[Date], sd, ed ) )
        )
)
