About
Kartika Purnima is the full moon that ends the month of Kartika, in November. The tithi at sunrise fixes the day for the Kartika snan (bath), and the evening of the same day is Dev Deepawali at Varanasi, when the ghats are lined with lamps. It is also Tripuri Purnima, recalling Shiva's defeat of Tripura, and the Sikh community keeps Guru Nanak's birthday on this full moon. The month of Kartika bathing, begun on Sharad Purnima, ends here, and the Pushkar fair in Rajasthan culminates on this day.
How it is observed
A river bath at dawn, lamps floated or lit on the ghats at dusk, and the Satyanarayana vrat in many homes.
