-   The "VEVENT" is also the calendar component used to specify an
-   anniversary or daily reminder within a calendar. These events have a
-   DATE value type for the "DTSTART" property instead of the default
-   data type of DATE-TIME. If such a "VEVENT" has a "DTEND" property, it
-   MUST be specified as a DATE value also. The anniversary type of
-   "VEVENT" can span more than one date (i.e, "DTEND" property value is
-   set to a calendar date after the "DTSTART" property value).
