What do you call a phrase like "A few days ago, ..." or "Last Monday, ..."?
For example, "A few days ago, I went shopping" or "Last Monday, I finished reading my book"
I was thinking that it was an appositive, but I'm not sure.

An appositive contains two nouns, so the phrases, which you gave as examples, are not appositives.
I don't think, there is a general term for this kind of phrases.
I would call them adverbial phrases [of time]; "temporal adjunct" describes their particular function. https://en.m.wikipedia.org/wiki/Adverbial_phrase
