Except the wall calendar has the current month on it in big letters, so all you need to know is what month it is.
This thing does not tell you if it's showing you the days for Jun or Jul
also the entire point of a wall calendar is that you can make notes on specific days, isn't it?
>You need to remember to slide the frame every month
And if you have a wall calendar you have to remember to tear down the page of the previous month every month...
