From this custom, the root was borrowed for the familiar meaning of holiday, celebration and festivity.
The Hajj is associated with the life of Islamic prophet Muhammad from the 7th century, but the ritual of pilgrimage to Mecca is considered by Muslims to stretch back thousands of years to the time of Abraham.
However, even if they choose to perform the Umrah, they are still obligated to perform the Hajj at some other point in their lifetime if they have the means to do so, because Umrah is not a substitute for Hajj.
Judaism uses circumambulation in the Hakafot ritual during Hoshanah Rabbah at the end of the Festival of Sukkot and on Simchat Torah; traditionally, Jewish brides circumambulate their grooms during the wedding ceremony under the chuppah.
Because the Islamic calendar is lunar and the Islamic year is about eleven days shorter than the Gregorian year, the Gregorian date for Hajj changes from year to year.
Thus, each year in the Gregorian calendar, the pilgrimage starts eleven days (sometimes ten days) earlier than the preceding year.
