"Data"

Translation: A date

[Bob20020]

Can this mean a date, as in what day it is, or a date, as in going out to eat with a boy/girlfriend?

[immery]

only what day it is.

In the text-to-speech, it kind of sounds like the accent is on the second syllable. Is that correct?

[Jellei]

I am bad with recognizing where the accent is. Anyway, in Polish the accent is almost always at the second-to-last syllable. If you hear it somewhere else, it's for 95% the case of an imperfect audio.
