Different views wil have slightly different values for SelectedDate because of the granuality of that view (e.g. a particular view might need to change the Hour component when the last view was only concerned with Day component).
To maintain a single value, you can keep a SelectedDate property in your view model/code that has a specific value. Use that property to set the control's SelectedDate property after the view changes.
For example, a one-way binding:
To answer your quesiton about the difference between SelectedDate and DisplayDate, DisplayDate is set t make the control go to the area of the view that has that date, even if you don't force a selection. For example, DisplayDate would be DateTime.Noow, while SelectedDate can be tomorrow.
You can learn more about DisplayDate in the Date Properties
