If you change the date and apply the change to all occurrences, the new date
becomes the start date of the repeating event. The end date is adjusted to
maintain the same duration.
If you change other repeat settings (such as time, alarm, or private) and apply
the change to all occurrences, a new event is created. The start date is the day you
made the changes. Past occurrences are not changed.
If you make a change to one occurrence of a repeating event (such as time), that
occurrence no longer shows the Repeat icon.
There are three ways to delete an event from the Date Book application. If you are
deleting a single event, you can use any of these three methods. If you are deleting
a repeating event, two of the methods allow you to choose which occurrences of the
event you want to remove.
If you erase one instance of a recurring event, all instances of the event are removed.
