12th month of the Islamic lunar year
The Hajj (also known as Haj or Hadj) is the greater Muslim pilgrimage to Mecca, which all able-bodied Muslims who can afford it are expected to make at least once in a lifetime. It is one of the Five Pillars of Islam.
The Hajj takes place from the 8th to the 12th days of the 12th and last month of the Islamic lunar year, which does not coincide with the Gregorian calendar used by the Western world (in fact it falls about 11 days earlier each year in the Gregorian calendar).
