Mecca

One of a Muslim's duties, as described in the Five Pillars of Islam, is to go on Hajj at least once during his or her lifetime. This is a pilgrimage to Makkah (Mecca) in Saudi Arabia. Approximately two million Muslims went in 1999, of which about one million were from Saudi Arabia, and 6,000 were from the U.S. 1 Council on American-Islamic Relations estimated in 2006 that "some 10,000 American Muslims go on Hajj each year." 7 The number of American pilgrims is increasing yearly. Followers of Islam who cannot go on a Hajj because of ill health or lack of money are excused from the obligation. If one assumes that Muslims go on Hajj a maximum of once during their lifetime, that the number of Muslims in America are about 6.5 million, and that the typical age span for pilgrims is 60 years, then fewer than 10% of American Muslims take part in the pilgrimage.
The Council on Islamic Education states:
"The Hajj consists of several ceremonies, meant to symbolize the essential concepts of the Islamic faith, and to commemorate the trials of prophet Abraham and his family...Prophet Muhammad had said that a person who performs Hajj properly 'will return as a newly born baby [free of all sins].' The pilgrimage also enables Muslims from all around the world, of different colors, languages, races, and ethnicities, to come together in a spirit of universal brotherhood and sisterhood to worship the One God together
The Hajj formally begins on the eighth day of Dhul-Hijjah (Zul-Hijjah) - the 12th month of the Muslim lunar calendar. Dr. Monzur Ahmed writes:
"Islamic months begin at sunset on the day of visual sighting of the lunar crescent [following the new moon]... Although it is possible to calculate the position of the moon in the sky with high precision, it is often difficult to predict if a crescent will be visible from a particular location... Usually the moon has to be at least 15 hours old before it can be seen from somewhere on earth." 3
