Ganga Sagar Mela is held every year on Makar Sankranti. It is organized at Sagar Island near Kolkata, where the Ganga breaks into hundreds of streams and merges into the sea. Ganga Sagar is one of the significant pilgrimage places for Hindus. The annual Ganga Sagar Mela is the largest fair by the number of pilgrims who visit it except Kumbh Mela.
It is believed to be the place where ashes of Raja Bhagiratha's ancestors were purified by the holy water of Ganga.
Ganga Sagar Mela is held for about 4 days but the most important Snan day falls on Makar Sankranti day. The most auspicious time to take holy dip is during dawn hours just before sunrise.
In 2013, due to Kumbh Mela at Allahabad the number of pilgrims visiting Ganga Sagar should be less compared to last year.
