Eid Mubarak or (Arabic: عيد مبارك) is a Muslim greeting reserved for use on the festivals of Eid al-Adha and Eid al-Fitr. Eid means "celebration", and Mubarak means "blessings". In the social sense, people usually celebrate Eid al-Fitr after Ramadan and Eid-al-Adha in the month of Dhul Haj (12th and Final Islamic month). Some state this exchange of greetings is a cultural tradition and not part of any religious obligation. However, it is only used during the celebration of the two Muslim holidays. 
Throughout the Muslim world there are numerous other greetings for Eid ul-Adha and Eid ul-Fitr. The companions of the Prophet Muhammad used to say to each other when they met on Eid ul-Fitr: Taqabbalallâhu minnâ wa minkum (which means "[May] God accept from us and you [our fasts and deeds]"). Throughout the Muslim world, variations in Eid greetings exist.
Speakers of Arabic might also add "kul 'am wantum bikhair" (كل عام و أنتم بخير), which means "May you be well with every passing year."
