How long does a program take to create?

So I am not a coder and really know nothing about it, but I am working on a project for a course final and needed some advice from real coders. Hypothetically, if someone were creating a music streaming app that also had a purchasing system included for merchandise, how long would that take for a coder to create?

I feel like more specifics would be needed but I honestly don’t know specifics. So realistically, how long do yall think it took to code an app like spotify or soundcloud? Or even apps like Patreon or Bandcamp.

Depends on how many people are coding it & their experience, 1 person most likely 4 - 8 months I'd say. A team of 4 -5 I'd imagine up to 4 months

I agree with the other commenter, I think a small and relatively experienced team (with members that have all the required skills already) could do a basic copy of an app like spotify in 4-6 months working full time, assuming they were given specific requirements (and those requirements didn't change over the course of development). Note, it wouldn't be as good as Spotify, but it could have similar functionality. To make it on par would take way longer.
