+- CalendarTime
+Calendar Time supports creating formats for displaying the return string. The format works in the standard DateTime format string manner
+
+```csharp
+var startDateTime = new DateTime(2012, 12, 12);
+var sameDay = new DateTime(2012, 12, 12, 12, 0, 0);
+var endDateTime = new DateTime(2012, 12, 13);
+var calendarTime = startDateTime.CalendarTime(endDateTime); // Tomorrow at 00:00 AM
+calendarTime = endDateTime.CalendarTime(startDateTime); // Yesterday at 00:00 AM
+calendarTime = startDateTime.CalendarTime(sameDay); // Today at 12:00 PM
+```
