My train leaves / departs at seven o’clock tonight.

[Alice Chu]

Hello.
Could you please tell me if my understanding is correct?

Begin, start, end, open, close, leave, depart, arrive, be, and have can be used with simple present tense to indicate a timetable / schedule in the near future.

1) The final exam starts on Monday and ends on Wednesday.
2) The orchid exhibition opens tomorrow and closes next Sunday.
3) The movie is at 7:00 tonight.
4) I have an appointment with my friends at 7:00 tonight.
5) The next train arrives in ten minutes.
6) My train leaves / departs at seven o’clock tonight.
→The action is fixed and regular in the near future.
7) We leave at seven o’clock tonight.→wrong
→The sentence is wrong because the action is not regular.

They're all OK — even #7.

Wow! The people sitting that exam are going to be VERY tired. I don't think the exam runs from Monday to Wednesday. I think you need "exams/start/end".
