This is the start of the second week in game, and it should be Monday the 8th, not Sunday.
The shops were closed "yesterday", and still are "today".
I've been having the same issue. It looks like the date increment by one but the day of the week is all over. I went from sunday to tuesday. But I also stuck on sunday a number of times. It's basically Sunday much more often that I wish it was.
Same issue. Everytime I quit the game and then log back in, it seems that the day of the week will reverse a day or two. Then when I sleep it pushes the day forward to the correct day of the week.
