"Good evening, goodbye."
question about godaften. seeing as all time after midday is afternoon and evening only means after 6pm wouldn't godaften mean good afternoon? not good evening?
These are circa numbers:
Kl. 06-9 er det morgen => godmorgen
Kl. 9-12 er det formiddag => godformiddag
Omkring klokken 12 er det middag
Kl. 12-18 er det eftermiddag => godeftermiddag
Kl. 18-24 er det aften => godaften
Kl. 24-06 er det nat. (But you only say godnat when you are going to bed, not as a greeting)
In this case 'aften' is a false cognate. It might sound like English 'after…' but it is actually a cognate with English 'even(ing)' (compare German 'Abend', ' Old Norse 'aptann', Old English 'ǽfen'). So it may sound like 'good after(noon)', but 'godaften' refers better to evening.
