ok thanks so would you mean this code should show
only EVENT where month=current month ?
thnaks
$today = date("d/m/Y");
$themonth=substr($today, 3,2);
$args = array (
'post_type' => 'EVENT',
'meta_key' => 'dates_%_date_EVENT',
'meta_value' => '[0-9]{4}' . $themonth . '[0-9]{2}',
'meta_compare' => 'REGEXP',
);
