Show upcoming events using wp_query?

Currently I have a query which works like a charm… the deal is that new year is coming and my code doesn’t support that very much, ugh.

Here’s the code.

<?php
$today = date_i18n( 'm d');
$agenda_query = new WP_Query(
	array ( 'post_type' => 'agenda_posts',
	 'posts_per_page' => '6',
          'offset' => '1',
	 'orderby' => 'meta_value',
	 'meta_key' =>  'evento_fecha',
	 'order' => 'ASC',
	 	'meta_query' => array(
		array(
		'key' => 'evento_fecha',
		'meta-value' => $value,
		'value' => $today,
		'compare' => '>=',
		'type' => 'CHAR',
		))
		)
	); 

?>

Basically it checks for a custom field called evento_fecha which has a date for example 12 16 for December 16, but it only works for posts of the same year, is there a way to implement it to receive the first events for the next year too?
