Or.... maybe it's really simple, because there's an HTTP API that
gives you the information. There's an API for everything these days. A
quick web search showed up this:

https://sunrise-sunset.org/api

Which means the project is a matter of taking the data and formatting
it. (Also probably getting lat/long from the phone's location API.)
I'd say this is a good-fun project - a one-week project for a student,
a weekend project for an expert. And yes, there WILL be edge cases to
deal with, but for the most part, it shouldn't be too hard.
