Kumbh Mela or Kumbha Mela is a mass Hindu pilgrimage of faith in which Hindus gather to bathe in a sacred or holy river. Traditionally there are four Kumbh Melas that periodically rotating. They are taking place in Allahabad (Prayagraj), Haridwar, Nashik district (Nashik and Trimbak), and Ujjain. The main festival site is located on the banks of a river Ganges and the Yamuna and the invisible Sarasvati at Allahabad. Bathing in these rivers is thought to cleanse a person of all their sins.
At any given place, the Kumbh Mela is held every 12 years. There is a difference of around 3 years between the Kumbh. The exact date is determined, following the Vikram Samvat calendar and the principles of Jyotisha, according to a combination of zodiac positions of Jupiter, the Sun and the Moon.
The exact age of the festival is uncertain. According to medieval Hinduism, Lord Vishnu spilled drops of Amrita (the drink of immortality) at four places, while transporting it in a kumbha (pot).
The festival is the largest peaceful gathering in the world, and considered as the “world’s largest congregation of religious pilgrims”. There is no precise method of ascertaining the number of pilgrims, and the estimates of the number of pilgrims bathing on the most auspicious day may vary. An estimated 120 million people visited Maha Kumbh Mela in Allahabad over a two-month period, including over 30 million on a single day,
