How is the hotel room opening time calculated?

Generally, rooms are opened after 6 a.m. (sometimes 7 a.m.) in the morning, and one day is counted until 12 noon the next day (sometimes 2 p.m. the next day). If you do not check out before 12 noon the next day, then another half day will be counted if you check out before 6 pm the next day, and another day will be counted if you check out after 6 pm the next day.

Anyone who rents a room before 6 a.m. (sometimes 7 a.m.) in the morning is considered to have rented a room since yesterday.

Competition is fierce now, and many hotels can negotiate the above rules.
