I said this evening instead of afternoon and got it wrong. Does noche mean evening and night? Approximately what time is the cut-off between noche and tarde?
I think technically that evening=tarde (not noche), but that most people would translate tarde as afternoon. Therefore your answer should probably be accepted. I generally think of the cut-off as 6pm or dark; 12-6pm = tarde, 7pm-12am = noche.
