If the Calendar app is closed, Siri may be the fastest way to reschedule an appointment. If you're already in Calendar looking at the appointment you've realized you need to reschedule, dragging the event and dropping it into the new time slot can be even faster than using Siri.
If you're not already there, tap on the day of the event you wish to change.



Next, Press and hold on the event until it becomes opaque in color




Now you can drag the event up or down to a new time slot or left or right to a different day.



You can also place your finger on one of the small circles on the top or bottom and drag to adjust the event's start or end time.



You won't be able to change events someone else has created and invited you to.
