Breakdown of Jutro idziemy na mecz na nowym stadionie.

Why does idziemy look like present tense if the sentence means something about the future?

In Polish, the present tense of an imperfective verb is very often used for a planned future.

So idziemy literally looks like we are going / we go, but in a sentence with jutro (tomorrow), it naturally means:

We’re going tomorrow / We’re going to go tomorrow.

This is very similar to English We’re going tomorrow, where the form looks present but the meaning is future because of the time word.

Could I also say Jutro pójdziemy na mecz na nowym stadionie?

Yes. That is also correct, but the nuance is a little different.

idziemy suggests a plan or arrangement already in place
pójdziemy is a perfective future, often sounding more like we will go

So:

Both can work, but idziemy is especially common for fixed plans.

Why is na used twice?
