Hoy es el Día de la Diosa, aquí hay un calendario que muestra la fecha actual y el calendario lunar, así como festivales especiales
1. Crear una nueva aplicación de formulario CustomCalendarDemo
Cambie el nombre del Form1 predeterminado a FormCustomDate y el formulario FormCustomDate se diseñará como se muestra en la figura:
