Eid Mubarak or Blessed Eid (Arabic: عيد مبارك, Bengali: ঈদ মোবারক, Pashto: اختر مبارک, Persian/Urdu: عید مُبارک, Sindhi: عيد مبارڪ,Malayalam: ഈദ് മുബാറക്, Somali: Ciid wanaagsan, Turkish: İyi bayramlar,Tamil: ஈத் முபாரக், Malay: Selamat Hari Raya) is a traditional Muslim greeting reserved for use on the festivals of Eid ul-Adha and Eid ul-Fitr. Eid means "celebration" and refers to the occasion itself, and Mubarak means "blessed"; for example, performing the Eid prayer. The celebration continues until the end of the day for Eid al-Fitr and continues a further three days for Eid al-Adha. However, 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), greetings like "Eid Mubarak". 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.
