If your requirements have not yet been realized, I have performed the relevant tests based on the data you have since provided, which I hope will be helpful to you.

According to your description, you want to see how many work items are opened and closed per month.
Here is my test

M_EntryNum = 
CALCULATE (
    COUNTROWS ( 'Table' ),
    FILTER (
        ALL ( 'Table' ),
        'Table'[Entry Date] >= MIN ( 'Calendar_'[Date] )
            && 'Table'[Entry Date] <= MAX ( 'Calendar_'[Date] )
    )
)

M_CloseNum = 
CALCULATE (
    COUNTROWS ( 'Table' ),
    FILTER (
        ALL ( 'Table' ),
        'Table'[Close Date] >= MIN ( 'Calendar_'[Date] )
            && 'Table'[Close Date] <= MAX ( 'Calendar_'[Date] )
    )
)

Here is the test data:

Calendar_ = CALENDARAUTO()
