ترجمة - انجليزي-يونانيّ - happy eid ul-fitr

Going by the French. You could very well just say "happy eid", but it's not as clear what you're referencing in English without context, and the holiday is generally known in English by the full "Eid ul-Fitr". Suggestions welcome on that point.

Εΐντ ελ Φτρ is also called "«μικρό μπαϊράμι" and "Κιτσίκ Μπαϊράμ"
