Kumbh mela is a mass hindu pilgrimage of faith in which hindus gather to bathe in a sacred river. It is the world's largest religious gathering, with 80 million people expected in 2013. It is held every third year at one of the four places by rotation: haridwar, allahabad (prayag), nasik and ujjain. Thus the kumbh mela is held at each of these four places every twelfth year ardh ("half") kumbh mela is held at only two places, haridwar and allahabad, every sixth year. The rivers at these four places are: the ganges (ganga) at haridwar, the confluence (sangam) of the ganges and the yamuna and the mythical saraswati at allahabad, the godawari at nasik, and the shipra at ujjain.kumbh means a pitcher and mela means fair in hindi. The pilgrimage is held for about one and a half months at each of these four places where it is believed in hinduism that drops of nectar fell from the kumbh carried by gods after the sea was churned.
