If I study all day tomorrow, a should be able to figure out who the artist is just by looking at the painting about half of the time.
For the few works I know a bit better I might remember the name, otherwise I’ll just hope it is one named in English after the subject (e.g. Carriage at the Races).
There is pretty much no chance of me remembering any of the dates.
All in all, I can only help that I can spot enough details to discuss (e.g. broad brush strokes, complementary colours, etc.) to balance out my lack of names/dates.
