Akin to Kumbh Melain North India, Mahamagamis religiously famous in South India. This takes place once in twelve years, in Kumbakonam in Tanjore District, an old town with innumerable famous temples, in the Tamil month of Masion Full Moon Day when the star is Magamon that day. This year, it falls on March 6.
It is believed that on this day, all the nine sacred Rivers of Bharat converge in the nine wells in the Temple Tank known as Mahamagam Tank and it is believed to be sacred for anyone to take a bath in the Tank on that day to ward off evil influences.
The Temple Tank known as Mahamagam Tank is 12 Acres in area and has well-laid out steps on all the four sides. In the centre of the tank, there are 9 wells in which the Holy Rivers converge. On the four banks of the Tank, there are 16 Sannathis for 16 Mahalinga Swamis, known as Shodasa Lingas. (These 16 temples are said to have been built by one Sri Govinda Deekshitar, who was the Chief Minister for the King, Achuthappa Naicker around 1545 A.D. The King gave him gold by his weight, with which he has built these temples.)
Over 50 lakhs pilgrims are expected to come for this Mahamagam festival and take a holy dip in the Tank. About 20,000 police personnel have been mobilized to take care of security with tension having increased in the Police circle on account of the expected visit of the Chief Minister, Jayalalithaa.
When Lord Guru (Venus) enters Leo on February 26, the tanks get the sanctity and hence, though Mahamagam falls on March 6, a dip in the tank on any day between February 26 and March 6 is considered sacred. Dhwajarohanam (Flag hoisting) was done on February 26
It is learnt from an Inscription that King Krishna Devaraya took bath in this temple on 24th February 1518 and distributed lot of presents to all. From this it will be clear that Mahamagam was celebrated even in 1518 A.D. and this should have been in observance from time immemorial.

It is just the Kumbh Mela of the South India. Kumbha Konam a town near Thanjavur derives it names from 'Kumbh' or pot which settled after the great 'pralaya' that covered the earth with water. The pot contained seeds of all life forms, hence Kumbakonam.
Brahma was advised by Lord Shiva to put the Germs of all creation into a pot or vessel caped with a coconut, and save it. When the Pralaya destroyed the earth and covered it with water, the pot alone survived and settled that later became Kumbha Konam. The festival occurs once in 12 year, when Maha star, falls on Simha rasi. All the sacred rivers of India are said to come here during the auspicious hours and cleanse themselves. One can judge the age of the festival, by the fact, that it mentions the long bygone rivers like Saraswati and Kumari. Saraswati was in the North while Kumari river was beyond the present Kanyakumari i.e. in the Indian Ocean, when that part of India was still intact and not swallowed by the sea.
