According to astrologers, the 'Kumbh Fair' takes place when the planet Jupiter enters Aquarius and the Sun enters Aries. Kumbh (Kumbha means pot) Mela (means fair) is a sacred Hindu pilgrimage. It takes place at the following four locations of India: Prayag, Allahabad (Uttar Pradesh) , Haridwar (Uttarakhand) , Ujjain (Madhya Pradesh) , Nasik (Maharashtra)
Kumbh Mela is celebrated four times every 12 years, the site of the observance rotating between four pilgrim places on four sacred rivers: at Haridwar on the Ganges river, at Ujjain on Shipra, at Nasik on Godavari, and at Allahabad on the confluence of the Ganges, Yamuna and the mythical river Sarasvati. For each site Kumbh Mela comes in every 12 years. Each site’s celebration is based on particular zodiacal positions of the Sun, the Moon, and Jupiter, the holiest time occurring at the exact moment these zodiacal conditions are fulfilled. It is the largest gathering of people for a religious purpose in the world. Millions of people gather on different places for this auspicious occasion.
