Eid Mubarak is a popular Muslim celebration in most part of the world. Eid means "Celebration" and refers to the occasion itself, and Mubarak means "blessed". It can therefore be said that Eid Mubarak means "blessed celebration"
During this time of the year, Muslim performs 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". This exchange of greetings is a cultural tradition and not part of any religious obligation.
