Kartik Purnima and Dev Diwali: Meaning, Significance, and Celebration

Kartik Purnima is the full moon that closes Kartik, one of the most sacred months in the Hindu calendar, and in Varanasi this same night is celebrated as Dev Diwali — “the Diwali of the Gods” — one of the most visually striking festival evenings in India, when the ghats along the Ganga are lit with thousands of oil lamps.

When it falls

Both fall on the full moon (Purnima) of the lunar month of Kartik, typically in November, roughly two weeks after Diwali. Check a current panchang for the exact date in a given year.

Why Kartik is considered so sacred

The entire month of Kartik is traditionally treated as especially auspicious for devotion, charity, and pilgrimage, particularly for Vishnu worship — Tulsi Vivah, Vishnu’s symbolic wedding to the Tulsi plant, also falls within this month. Kartik Purnima marks the culmination of this sacred period, and many devotees observe fasting, river bathing, and charitable giving on this day specifically.

Dev Diwali in Varanasi

While Kartik Purnima is observed across India in various ways, its most famous expression is Dev Diwali in Varanasi, where the ghats along the Ganga are illuminated with an enormous number of oil lamps (diyas), accompanied by grand aarti ceremonies. Tradition holds that on this night, the gods themselves descend to bathe in the Ganga and celebrate — hence “the Diwali of the Gods.” The event has grown into one of India’s most visually spectacular annual festival evenings, drawing visitors from across the country and beyond.
