In my duolingo course FR-IT there was the sentence "In Italia, non arrivate mai in anticipo" (In Italy, never arrive early)
In Germany there is the saying: "fünf Minuten vor der Zeit, sind die wahre Pünktlichkeit" what I learned is "five minutes early, would be what I call true punctuality" (when I look for the rhyme again)
Now I wonder: what is it like in other countries? Where should you be very punctual, where should you rather be a bit early or even a bit late..?
