A lot of things changed with Elements 11, including the available display views. There is no longer a calendar view like in Elements 10 and before. The closest available is to go to the Events page (click Events in the top bar), and then switch from Events to Smart Events (just below the top bar). This will group all of your images into the day on which they were shot. However, it doesn't separated them on a calendar and leave you the blank spaces where no images were taken.
