2023 India 9-14 Nov : Dev Diwali in Varanasi
The Dev Deepavali (“the Diwali of the Gods” or “Festival of Lights of the Gods” is the festival of Kartik Poornima celebrated in Varanasi, Uttar Pradesh, India. It falls on the full moon of the Hindu month of Kartika (November – December) and takes place fifteen days after Diwali.
During Dev Deepawali, houses are decorated with oil lamps and coloured designs on their front doors. Firecrackers are burnt at night, processions of decorated deities are taken out into the streets of Varanasi, and oil lamps are set afloat on the river. Owing to the significance and the growing socio-cultural popularity of this festival, it has now also come to be celebrated in nearby districts such as Mirzapur.
