Suppose that my wife and I talk to another couple and set a time to go to the beach with them and spend some with that couple over there. What is this arrangement and its time called? Can it be called an appointment? For example how would you say that the other couple want to postpone this arrangement and the set time?
- They called and want to postpone the appointment / rendezvous/ catch-up / arrangement / meeting.
- They cancelled the appointment / rendezvous / ... .
I know that most of these option are fine. But I don't know which ones are actually used by native speakers and will appreciate some usage examples in the case of time and place arrangements with friends.
