要按年份描述和月份ASC显示列表，请执行以下操作：

使用custom\\u post更改您的帖子类型。

global $wpdb;

$posts = $wpdb->posts;

$sql = "SELECT DISTINCT(YEAR(`post_date`)) as years FROM $posts WHERE post_type = \'custom_post\' ORDER BY years DESC"; //Get all post year list by DESC

$result = $wpdb->get_results($sql);

foreach($result as $rs) {
    echo \'<h2>\'.$rs->years.\'</h2>\';
    $args = array(
        \'post_type\' => \'custom_post\',
        \'post_per_page\'=> -1,
        \'post_status\' => \'publish\',
        \'orderby\'   => \'date\',
        \'order\' => \'ASC\',
        \'date_query\' => array(array(
            \'year\'=> $rs->years,
        ),),

    );

     $loop = new WP_Query($args);

     if($loop->have_posts()) {

        while($loop->have_posts()) : $loop->the_post();

            echo \'<a href="\'.get_permalink().\'">\'.get_the_date().\'</a>\';
        endwhile;

     }
}
