Order posts by event date

Hello!
How can I order my posts by the event date?
I have following code for my meta field:

function event_date_get_meta_box( $meta_boxes ) {
	$prefix = 'eventdate-';

	$meta_boxes[] = array(
		'id' => 'untitled',
		'title' => esc_html__( 'Veranstaltungsdatum', 'event-date' ),
		'post_types' => array( 'post' ),
		'context' => 'advanced',
		'priority' => 'default',
		'autosave' => false,
		'fields' => array(
			array(
				'id' => $prefix . 'event-date',
				'type' => 'date',
				'name' => esc_html__( 'Veranstaltungsdatum', 'event-date' ),
			),
		),
	);

	return $meta_boxes;
}
add_filter( 'rwmb_meta_boxes', 'event_date_get_meta_box' );
