5am to 5pm seven days a week sounds likely.
I think the 5am to 12 noon was just to get through the holiday period with fewer big social gatherings.
People will adjust and big crowds in the supermarket should lessen as people get accustomed to the new schedule.
I am wondering how the guys and street girls are managing. 5 pm to 5 am is a long time, and 12 noon to 5 pm is even longer. Unlikely that most spend the entire time in bed. Do we need to start stocking books and board games in our rental apartments
