Is there a way to know which timezone (e.g. America/Phoenix) I'm in right now?

I did actually missed a meeting due to that. I was in small city in Montana, checked list of these timezones, but didn't know which one to choose. So I saw Phoenix has the same time as me, and set it at my device.

However, turned out that Montana actually uses America/Denver (which is Colorado) as their timezone. Is there a way to know that?

the general rule of thumb for American Timezones is that Arizona is its own special thing and as long as you stay out of that state then you're in America/{los_angeles|denver|chicago|new_york} for pacific, mountain, central, and eastern respectively.

Just stay away from Arizona and American time zones are easy and what you did would work.

Arizona is special because it's in mountain time, it doesn't observer daylight saving time so half the year it has the same time as pacific time except for the Navajo Nation which does observe daylight saving time but the Hopi Nation which is entirely inside the Navajo Nation doesn't follow daylight saving.
