Fonction calendrier solaire à calendrier lunaire

1, Idée de conception :

Pour calculer quel jour du calendrier lunaire correspond une heure donnée, nous devons trouver une heure de référence, puis utiliser cette heure de référence pour calculer les heures futures. Calculez d’abord le nombre de jours de différence entre l’heure actuelle et l’heure de référence, puis en trouvant le nombre de jours dans chaque année du calendrier lunaire, calculez à quel jour de l’année correspond l’heure actuelle, et enfin calculez à quelle date appartient à ce mois-là.

2, créez un nouveau fichier Convert.class.php ;

encapsulez la fonction de conversion, le code est le suivant :
