Let's say there is an appointment between John and Peter, scheduled for yesterday at 7am.
An appointment might be "cancelled", which means that it didn't happen.
But, what word(s) would you use to describe the appointment was "completed" (i.e. John and Peter met yesterday at 7am).
Is it right to say "Did the appointment took place?" or "The appointment happened"?
Note that I'm interested in the point of view of the appointment itself, not the people involved in it.
