jim912さん、ご返信ありがとうございます。
まず試しに、general-template.phpをコピーしてバックアップをとって、tfootの月送りをtheadに移動しました。
しかし、カレンダーを設置しているヘッダーのスペースを考えるとあと一行削りたいと思っており、文字の大きさも大きめに設定しているのでカレンダーを小さくする訳にもいきません。
それで<caption></caption>の両サイドに月送りを表示させるか、それが駄目なら<caption></caption>内に月送りのコードを入れようとしていますが、いずれも上手くいきません。
<caption></caption>内に月送りのコードを入れる場合、どうしたらいいでしょうか。
変更後のコードは以下の通りです。
function get_calendar($initial = true, $echo = true) {
global $wpdb, $m, $monthnum, $year, $wp_locale, $posts;
$cache = array();
$key = md5( $m . $monthnum . $year );

if ( is_array($cache) && isset( $cache[ $key ] ) ) {

echo apply_filters( 'get_calendar', $cache[$key] );
return;
} else {
