(ical:define-property ical:duration "DURATION"
  "Duration.

This property specifies a duration of time for a component.
In an `icalendar-vevent', it can be used to implicitly specify
the end of the event, instead of an explicit `icalendar-dtend'.
In an `icalendar-vtodo', it can likewise be used to implicitly specify
the due date, instead of an explicit `icalendar-due'.
In an `icalendar-valarm', it used to specify the delay period
before the alarm repeats.

If a related `icalendar-dtstart' property has an `icalendar-date'
value, then the duration must be given as a number of weeks or days."
