have (something) coming up (on a certain date)
The phrase "___ is coming up" means that something is scheduled, and is going to happen soon:
Sorry, I can't. Final exams are coming up in a couple of weeks.
The final deadline is coming up at the end of this month.
These examples are all about events that are scheduled for a certain day. But you wouldn't use "coming up" to talk about things that you're not sure about, like an earthquake.
