Would something like this be considered a ZK proof? https://crypto.stackexchange.com/questions/96232/zkp-prove-t...

No. ZK has a technical definition I don't want to get into, but note that the described system is deterministic and it always produces the same proof for Alice on a given day, and the proof for a later day can be derived from the proof for an earlier day. So two proofs can be linked back to Alice, and thus the system is not ZK. You need some kind of randomness for ZK.
Makes sense.
