This is a little bit of a tricky one, as you have to consider both
start_month and end_month as special cases - so you need a three-part
conditional, for the start month, the end month, and the months in
between. Something like this:

SELECT * FROM `introduction_messages`
 WHERE (month>`start_month` AND month<`end_month`)
       OR (month=`start_month AND day>=`start_day`)
       OR (month=`end_month` AND day<=`end_day`);
