Islam is one of the three major Abrahamic faiths, alongside Judaism and Christianity. According to the 2020 U.S. Religion Census, the number of followers of Islam in the United States is 4.5 million.1 Muslims annually observe two major holidays: Eid al-Fitr and Eid al-Adha. This fact sheet describes the two holidays' significance and American Muslims' observance of them and addresses the ways the holidays have been recognized by elected officials. The fact sheet also briefly describes two other widely celebrated Muslim holidays.
This fact sheet is designed to assist congressional offices with work related to Islamic holidays. It contains sample speeches and remarks from the Congressional Record, presidential proclamations and remarks, and selected historical and cultural resources. This is part of a series of Congressional Research Service fact sheets on religious holidays in the United States.
Muslims have been celebrating Eid (Muslim festival) holidays for the past 1,400 years.2 In general, Muslims observe two key holidays: Eid al-Fitr and Eid al-Adha. The dates for these two holidays are determined by tradition according to the Islamic or Hijra calendar, which follows the lunar year and is determined by the sightings of the new moon with the naked eye.3 The dates for Muslim holidays change every year. Following the Hijra or lunar calendar, the holidays move forward approximately 11 days each year on the Gregorian calendar.
Eid al-Fitr is often celebrated for one day each year at the end of the approximately 30-day month of Ramadan,4 during which many Muslim adults fast daily from sunrise to sunset and give charity to the poor and needy. Fasting for Ramadan is one of the five pillars of Islam.
Depending on the country, Eid al-Adha is celebrated from 4 to 12 days at the end of the Hajj (pilgrimage, the fifth pillar of Islam)5 to Mecca and Medina. Annually, nearly 2 million Muslims participate in the Hajj from approximately the 10th to the 13th of the month of Dhu al-Hijjah, the last month in the Islamic calendar.6 Eid al-Adha commemorates the dream in which God appeared to Ibrahim (known as Abraham to Christians) and asked him to sacrifice his son Ishmael as an act of obedience. According to religious tradition, God intervened and requested that a sheep be sacrificed in Ishmael's place. Muslims generally consider Eid al-Adha the holiest festival on the Islamic calendar.7
For the Eid holidays, homes are often decorated and, after communal prayers, Muslims wear their finest clothes. Muslims in the United States may sacrifice an animal or purchase an animal that was sacrificed according to halal standards in observance of Eid. The meat may be given, along with other gifts, to family, friends, neighbors, and the less fortunate. This is known as zakat, a religious obligation for Muslims, and it is the third of the five pillars of Islam. In Arabic, zakat means charity, purification, growth, and blessing. Paying zakat is meant to remind Muslims to appreciate the blessings that Allah has bestowed upon them and help empower those who have less.8
At the completion of both Eids, people may say "Eid Mubarak" to one another. This is an Arabic salutation meaning blessed Eid or blessed celebration. Muslims often wish each other Eid Mubarak after performing the Eid al-Adha prayer.9
This section provides selected examples of Muslim celebrations. The Guibord Center–Religion Inside Out provides a list of Muslim celebrations, along with descriptions of their significance.10
For Shi'a Muslims, Ashura commemorates the murder and subsequent martyrdom of Husayn, grandson of the Prophet Muhammad, on the 10th day of the Islamic lunar month of Muharram.11 It is generally observed through wearing black clothing, engaging in lamentation (and sometimes self-flagellation), and fasting.12
Mawlid celebrates the birthday of the Prophet Muhammad. Its legitimacy has been a topic of intense debate within the Muslim world, but it is recognized by most denominations of Islam and is a national holiday in most Muslim-majority countries, with the exception of Saudi Arabia and Qatar.13 Mawlid is celebrated during Rabi' al-awwal, the third month in the Islamic calendar.14
Observance of Muslim holidays in the United States is determined at the local level. For example, some school districts close on the two Muslim Eid holidays. In 2015, New York City became the first large metropolis in America to recognize the two Eids as official holidays and closed its public schools in observance of Eid al-Fitr and Eid al-Adha.15 Local governments in Maryland,16 Massachusetts,17 Michigan,18 Minnesota,19 Virginia,20 and other states have similar observances.
In 2001, for the first time in American history, the U.S. Postal Service issued a U.S. postage stamp commemorating both Eids. Since then, there have been subsequent issues of Eid stamps, with the last one issued in 2016.21
