    Can you use the year and month to build a date? And then use that date to calculate your end date? Say you create a formula to find the first of the month after and then subtract one day from that. I have to test this, but possibly something similar:

    DATE_SUB(DATE_ADD(DATE(CONCAT(`Year`, '-', CASE WHEN LENGTH(`Month`) = 1 THEN CONCAT('0', `Month`) ELSE `Month` END, '-01')), INTERVAL 1 MONTH), INTERVAL 1 DAY)
