Unless you create an item at the end time I don't think you can do what you
want since typically people need to be reminded of an upcoming start.

How do we set events to alert us based on the end date or time rather than
the start date/time? Many events in our calendar span multiple days and it
would be very convenient to be reminded x hours/days before the event
ends.
Thanks in advance for your help!
