Add body_class if post has expired

I have a custom field where I can set expiry dates for posts.

What I want to do is to add a body class to posts that have expired but I am stuck.

I am thinking something along the lines of:

function add_acf_body_class($class) {
$expired = get_field('expiry_date', false, false);
$today = date('F j, Y');
	if($expired < $today) {
		$class[] = expired;
		return $class;
	}
}
add_filter('body_class', 'add_acf_body_class');

It’s adding the body class but it’s being added to all posts instead of posts that have expired.

function add_acf_body_class($class) {
  global $post;
  if (empty($post) || !is_a($post, 'WP_Post')) {
    return $class;
  }
  $expired = get_field('expiry_date', $post->ID, false);
  if ($expired) {
    $today = date('Ymd');
    if($expired < $today) {
      $class[] = 'expired';
    }
  }
  return $class;
}
add_filter('body_class', 'add_acf_body_class');
