The
Dev Deepavali is the festival of Kartik Poornima celebrated in the city of Varanasi in Bhojpuri region of Uttar Pradesh, India. It falls on the full moon of the Hindu month of Kartika and takes place fifteen days after Diwali. The steps of all the ghats on the riverfront of the Ganges River, from Ravidas Ghat at the southern end to Rajghat, are lit with more than a million earthen lamps (diyas) in honour of Ganga, the Ganges, and its presiding goddess. Mythologically, the gods are believed to descend to Earth to bathe in the Ganges on this day. The festival is also observed as
Tripura Purnima Snan. The tradition of lighting the lamps on the Dev Deepawali festival day was first started at the Dashashwamedh Ghat by Pandit Kishori Raman Dubey in 1991.
