in Egypt you say if you are talking to a man "kol sana wenta tayeb" to a woman "kol sana wenty tayeba" to a lot of people "kol sana wentom tayebeen" and you reply to a man: "wenta tayeb" to a woman: "wenty tayeba" to a bunch of people: "wentom tayebeen" :D so kol sana wenty tayeba :)

عيد سعيد عيد مبارك كل عام وانتم بخير عيد فطر مبارك كل عام بالخير يا رب عيد فطر مبارك Eid Fitr mubarak

in ramadan we said (" ramadan karime ") and the answer is ( " allaho akrame") ....and in eid el fitr we said ( " kollo aame wa antome bikhayere") and the answer is ( " wa antome bikhayere")...... :)

In my country...it would be.. " Selamat Hari Raya Aidilfitri & Maaf Zahir Batin" and people would answer the same phrase..
