Calendar basicCalendar = new Calendar();

// root is a Panel that is defined elswhere.
root.Children.Add(basicCalendar);

' Create a Calendar that displays 1/10/2009 
' through 4/18/2009. 
Dim basicCalendar As New Calendar()
basicCalendar.DisplayDateStart = New DateTime(2009, 1, 10)
basicCalendar.DisplayDateEnd = New DateTime(2009, 4, 18)
basicCalendar.DisplayDate = New DateTime(2009, 3, 15)
basicCalendar.SelectedDate = New DateTime(2009, 2, 15)

' root is a Panel that is defined elswhere. 
root.Children.Add(basicCalendar)

<!-- Create a Calendar that displays 1/10/2009
           through 4/18/2009. -->
<Calendar Margin="20" 
          SelectedDate="2/15/2009"
          DisplayDate="3/15/2009"
          DisplayDateStart="1/10/2009"
          DisplayDateEnd="4/18/2009"/>

Remarks

You can restrict the range of a Calendar by setting the DisplayDateStart and DisplayDateEnd properties. A user cannot scroll to or select dates outside of this range. If you set the SelectedDate property to a date that is before DisplayDateStart, DisplayDateStart is set to the same value as SelectedDate.
