We can use the present continuous to talk about definite future arrangements. We usually use a future time word (like ‘tonight’ or ‘next week’). In this case we have already made a plan and we are sure that the event will happen in the future.
- I’m meeting my father tomorrow.
- We’re going to the beach at the weekend.
- I’m leaving at three o’clock.
We can’t use stative verbs with the present continuous. If we want to talk about definite future arrangements with a stative verb, we usually use a different tense, like ‘be going to’.
· I’m going to be in Glasgow at the weekend. (NOT: I’m being in Glasgow at the weekend.)
