Friend!, if you have to cross post make sure you have all of the
newsgroups in to TO: statement before you send it. It stops you from
wasting other peoples time not knowing someone else had resolved your
problem already in another group!

First off, you should keep the date in the database the default format
'yyyy-MM-DD' as a DATE Type..

I am not handling leap years but gives you a start. You may want to
build a procedure to do all of this and include leap year:

$minAge = 24;
$maxAge = 54;

SELECT
LASTNAME,
FIRSTNAME,
ROUND(DATEDIFF(CURDATE(),birthday)/365) AS 'numberOfYears',
birthday
FROM table
WHERE
ROUND(DATEDIFF(CURDATE(),birthday)/365) <= $maxAge AND
ROUND(DATEDIFF(CURDATE(),birthday)/365) >= $minAge;
