Dev Diwali or Dev Deepawali is a Hindu festival observed in the Hindu month of ‘Kartik’, celebrated with great pomp and show in the Indian city of Varanasi, in Uttar Pradesh. Dev Diwali is the ‘Festival of Lights of the Gods’ and falls on the Kartik Purnima (full moon day), fifteen days after the celebrations of Diwali. It corresponds to the month of November-December in the Gregorian calendar. This religious ceremony is started by chanting of the holy Vedic mantras by the priests, lighting diyas at the ghats and the sparkling of fire crackers, to welcome and please the Gods and Goddesses.
