    <summary>Display a Calendar and/or allow the user to select a date.</summary>
    <remarks>
      <para>With a Calendar widget, dates are presented to the user one month at a time. Additional information and decorations can be added to the Calendar by using the <see cref="T:Gtk.CalendarDisplayOptions" /> enumeration with the <see cref="P:Gtk.DisplayOptions" /> property.</para>
      <para>Days can be highlighted on the Calendar with <see cref="M:Gtk.Calendar.MarkDay" /> or <see cref="M:Gtk.Calendar.SelectDay" />.</para>
      <para>The following example shows a method that creates a simple Calendar displaying day names, headings and week numbers.
    <example>
          <code lang="C#">
// Create a calendar with some simple display options
public Calendar CreateCalendar ()
{
    Calendar cal = new Calendar ();
    cal.DisplayOptions = CalendarDisplayOptions.ShowHeading  | 
                         CalendarDisplayOptions.ShowDayNames | 
                         CalendarDisplayOptions.ShowWeekNumbers;
    cal.DaySelected += new EventHandler(HandleDaySelected);
    return cal;
}
    </code>
        </example></para>
      <para>The following example shows a typical event handler that outputs the date when one is selected.
    <example>
          <code lang="C#">
// Typical event handler for capturing the selected date
void HandleDaySelected (object obj, EventArgs args)
{
    Calendar activatedCalendar = (Calendar) obj;
    Console.WriteLine (activatedCalendar.GetDate ().ToString ("yyyy/MM/dd"));
}
