DisplayDate: To specify the displayed date in the calendar control. Assign the date in the system date format.

SelectedDate: change the currently selected date. Used as the display date. If the control shows the old date we can change it to current using following code:
<Calendar SelectedDate="{x:Static sys:DateTime.Now}"/>

SelectionMode: it provides multiple modes for selection like “MultipleRange”. We can select a range of dates by using this property.

BlackoutDates: this control provides a feature of black out some dates means user cannot select some of the date blocked by system.
<Calendar>
<Calendar.BlackoutDates>
<CalendarDateRange Start="08.04.2013" End="08.04.2013"/>
<CalendarDateRange Start="08.16.2013" End="08.24.2013"/>
</Calendar.BlackoutDates>
</Calendar>
