Can the hotel wake-up phone system wake up the day before 12 am?

In the morning 12, the overnight review system will automatically charge the room rate! Generally, rooms from 12 am to 6 am are counted as rooms stayed the day before, and there will be an extra room charge for one day. You can set the system to charge automatically when you open a room, or you can charge manually! The management system of Beijing Ruitong Hotel we use is automatically charged. It is usually called the morning room.
