Date difference between 2 previous months

Hi all,

I am trying to calculate the storage time (in days) for unsold items, historically.

Let's say I bought product A in Jan 2022 and it is still stored today.

DATEDIFF(Sales[PurchaseDate], TODAY(), DAY),) gives me the storage time in days up until today.

I want a bar chart that shows storage time in Feb 2022, March 2022, ... Feb 2023.

I tried replacing TODAY() with MAX(Date[Date]) or SELECTEDVALUE(Date[Date]) with no success.

P.S. Sales table only has PurchaseDate adn SoldDate as date columns.

Some more info, my measure looks like this:

Datediff = CALCULATE( if( SELECTEDVALUE('Date'[MonthEndDate]) >= SELECTEDVALUE(Sales[PurchasedDate]) , DATEDIFF(SELECTEDVALUE(Sales[PurchasedDate]), SELECTEDVALUE('Date'[MonthEndDate]) , DAY), "f" ), USERELATIONSHIP(Sales[PurchasedDate], 'Date'[Date]))

And I get this result:

It only calculates the datediff to the month itself.
I want the difference to all following month ends.
