Eid is a word that is commonly used to refer to a Muslim religious holiday or festival. The two most important Eid festivals in Islam are Eid al-Fitr, which marks the end of the holy month of Ramadan, and Eid al-Adha, which commemorates the Prophet Ibrahim's willingness to sacrifice his son for God's sake. Eid al-Fitr is celebrated at the end of the month of Ramadan and Eid al-Adha is celebrated during the month of Hajj. During these festivals, Muslims around the world gather with family and friends, offer special prayers, exchange gifts, and enjoy traditional foods.
