"I do not have time on Saturday."
Translation:Cumartesi günü zamanım yok.
allright, so if I want to say: "I don't have time on saturday" like on this specific saturday, I have to use cumartesi günü (and -ü is the accusativ suffix, right?) and if it's "I don't have time on saturdays" like never on saturdays, I have to use cumartesileri (plural suffix and possessiv suffix?)?
