Përkthime - Greqisht-Anglisht - Καλημέρα αγάπη μου!

I believe "Good day" would be a better translation as 'Guten Morgen" would be good morning.

Well then both greek and french translations are wrong since they don't mean good day(Καλή σου μέρα/Bonne journee would be the right ones...).Sorry i was translating from greek not from german!

Guten Tag = Hello (less commonly: "Good day" )
Guten Morgen = Good morning
Bonjour = Hello/Good day and/or Good morning
Bonne journée = Have a good day (This does not mean "Hello"; it means "Goodbye"!)

good day
