    if ( ($query->is_month() || $query->is_day()) && $query->is_main_query() ) {
        $query->set( 'post_type', array('post','news', 'gallery') );
add_action( 'pre_get_posts', 'my_pre_get_posts' );

function my_getarchives_where( $where ){
    $where = "WHERE";
    $where .= " (post_type = 'post' OR post_type = 'news' OR post_type = 'gallery')";
    $where .= " AND post_status = 'publish'";
    return $where;
add_filter( 'getarchives_where', 'my_getarchives_where' );
