I am 30 next month or I am going to be 30 next month

I think you can use present as it is a fixed timetable

Am I right?

    I'll be 30 [years old] next month. I'm going to be 30 [years old] next month. Those are the most usual ways of saying this.

You can’t use simple present for a single event in the future; you need to use the simple future (will be) or going-to future (going to be): I will eat lunch at noon tomorrow.

Simple present can be used for repeated events that continue into the future: I eat lunch at noon every day.

    "You can’t use simple present for a single event in the future" - I disagree with this a bit. It's very common to use it for plans, like "I leave for France tomorrow."

  • @stangdon— I agree with you. Perhaps this is why future tense is no longer considered a valid tense anymore.

  • That is a matter of a pinion of hullers and pullers. Not everyone agrees with that.

  • @stangdon Is there a rule that says when that’s acceptable? I don’t do it myself, so I’ve never thought about it.

  • @StephenS It seems to be mostly used for things that are planned or scheduled, like "The show starts at 9 PM", or "The lease expires in 2055." By way of comparison, "It rains tomorrow" sounds really weird and wrong. I also think it's mostly used for simple statements: "When I retire, I move to California" sounds wrong.

In contrast to another answer, to me all three possibilities are perfectly normal. There is absolutely nothing wrong with I'm thirty next month.
