in the 'prepare' section, you register the var as 'birthdate' , then in bindparam , you use 'Date' as name field. choose between the two. the error is here. ( parameter not defined ) because Date is unknown for your bindparam statement.

about your PDO use :
you're missing the best part, the 'filtering by Types'

you only use the 'prepare' ( and 'bind' ) , it's simply a 'String build' as it.

read here, Types are used for filtering, and so strenghing security

$sth->bindParam('calories', $calories, PDO::PARAM_INT);
the last parameter is needed, it's the Type to use ,
without this one, you're just processing a string build only
