How do you wish someone a happy birthday in arabic? (egyptian dialect) I have seen both 'kol sana wenta tayeb' and 'sana helwa ya gameel'. What are the differences between these two phrases, and which is more commonly used? Is one more formal and the other more friendly/casual? Would it be appropriate to say both together as a birthday greeting? "sana helwa ya gameel, kol sana wenta tayeb" Thanks! (shukran)
