First N-Blank Date Value A= CALCULATE(MIN('Table'[Date]),FILTER(ALLEXCEPT('Table','Table'[Account]),'Table'[Value A]<>BLANK()))

First N-Blank Date Value B = CALCULATE(MIN('Table'[Date]),FILTER(ALLEXCEPT('Table','Table'[Account]),'Table'[Value B]<>BLANK()))

I have the exact scenario and I need to return the value A which is corresponding to the month in the result column. Possible?
