In English
There are three words
which mean your "Date" word.
These are those
The first is the true use of "Date"
which means a romantic meeting.
They both like each other
well I'm not sure about her
but, they both like each other
they go out somewhere
That's called a "Date"
The next kind of meeting you wouldn't call a "Date"
You wouldn't 'date' your dentist
Maybe- Some people would. I don't know
But in this case, when you meet your dentist,
that's not called a "Date"
That's called...
An appointment
Lawyer, doctor, psychologist...
People who provide a service to you
Third kind is this one...
Again, this one, we wouldn't call it a "date"
It's for business
so we'd call it a "Meeting"
For all of them you use the verb "Have"
But what about if you just meet a friend
There's no romance
No dentistry
and there's no business being discussed
What then?
How can you say "I'm meeting a friend"?
It's exactly that
If it's romantic, you "Have a date"
It's it's a service, like a doctor, lawyer, dentist...
you "Have an appointment"
If it's for business, you "Have a meeting"
If you're seeing friends, "You're seeing your friend"
or "You're meeting your friend". Both are okay.
So I hope that is a little more clear now
