An All Day Event is an event which is sorted first within the day, alpahbetically.
Timed Events are displayed in time order after All Day Events.
An All Day Event Recurrence is one of the repeating events that follow as a result
of an All Day Event being made a "repeating event." This type of event
would normally have the same name as the master (or parent) event in the series.
An All Day Detached Event is an All Day Event Recurrence Event that has been edited
or moved to a different day. Example: You have an event every Wednesday, but because
one Wednesday in the series is a holiday, the event was moved to Thursday and you
dragged that one event from Wednesday to Thursday. More technically - A detached
event is an event that was once a recurrence of another event, but was edited and
the changes were applied only to that event and not its siblings or parent. Detached
events are still associated with their parent event so deletion of the parent will
also delete the detached events. Note that a parent event could become a detached
event, but this is a special case creating both a Detached Event and an Exception
Event. See below.
An All Day Exception Event is a master (or parent) repeating event that was edited,
but the changes were not applied to the events in the series that it created. When
this happens two events then exist in the calendar for the master event: the new
Detached Event and the original parent event which becomes an Exception Event. In
other words, an Exception Event is the original master (or parent) event of a repeating
series that has been edited, but the rest of the series were left unchanged. The
Exception Event is not displayed in the calendar display, but it will remain in the
Event List. This is done so that you can further edit the original master event to
have it affect the repeating events it created. Note: the complexity of Exception
Events can be avoided by not editing or moving the master (or parent) event that
creates a repeating series. The need to do so would be very unusual.
The Timed Events listed above can be described in the same fashion as the All
The color of the icon is the background color of the event.
