Итак, я получил это

Примечание: неопределенная переменная: щелчок по дате

Я знаю откуда это, но я не знаю, как это решить. А также я пытаюсь сделать так, чтобы календарь начинался с текущего дня в URL. Не заставляя меня нажимать на этот день. Любая помощь с моими проблемами?

моя база данных

  `id` int(11) NOT NULL,

Ниже 

if(isset($_GET['day'])) {
    $day_clicked = $_GET['day'];
    $date_clicked = $year . '-' . $month . '-' . $day_clicked;
}

в вашем текущем коде добавьте еще один тест, чтобы увидеть, был ли установлен $ date_clicked, и, если это не так, продолжайте и установите его. 

if (!isset($date_clicked)) {
     $date_clicked = $year . '-' . $month . '-' . date('d');
}
