Kartik Purnima 2026: Holy Bath, Dev Deepawali and Significance

Tripuri Purnima, Dev Deepawali and a day many traditions share

The Puranas tell of Tripurasura, an asura whose three flying cities of gold, silver and iron could be destroyed only when they lined up, and of Shiva, who brought them down with a single arrow at that moment. The full moon of Kartika is remembered as the day of that victory, so it is called Tripuri or Tripurari Purnima, after Shiva as the enemy of the three cities. The gods are said to have celebrated with lamps, and the day became Dev Deepawali, the Diwali of the gods. In Varanasi tradition holds that the gods descend on this night to bathe in the Ganga, and the ghats are lit with lakhs of diyas to welcome them.

Vaishnava traditions add their own associations. Some Puranic accounts connect Vishnu’s Matsya avatar, the divine fish, with this day. Kartika is also counted as the holiest month for bathing and lamp-offering, and the month-long Kartik snan and deep daan vows reach their culmination on the full moon. The Tulsi Vivah season and the five-day Bhishma Panchak, both begun on Prabodhini Ekadashi, end here too.

For Sikhs, Kartik Purnima is the Prakash Purab, or Gurpurab, of Guru Nanak Dev, the first Sikh Guru. Gurdwaras hold an akhand path, an uninterrupted reading of the Guru Granth Sahib, sangats go out on prabhat pheris singing shabads in the early morning, and langar is served to all comers. For Jains the full moon marks the end of Chaturmas, and the pilgrimage up Shatrunjaya hill at Palitana in Gujarat reopens.

Sunrise for the bath, pradosh for the lamps

Kartik Purnima is the fifteenth tithi (lunar day) of the bright fortnight of Kartika, the full moon itself. Because a Purnima ends the month in the purnimanta system and falls in the bright half in the amanta system, both calendars call it Kartika Purnima. It usually falls in November, a fortnight after Diwali.

Two different rules apply on this day, and that is the main reason people find two dates when they search “Kartik Purnima kab hai”. The holy bath (snan) and the day’s vrat follow the Purnima that prevails at sunrise, the udaya tithi. Evening lamp festivals such as Dev Deepawali follow the Purnima that prevails during pradosh, the window after sunset. When Purnima begins in the afternoon of one day and ends before the following evening, the first day has a full-moon evening and the second a full-moon sunrise, so Varanasi’s Dev Deepawali can come a day before the snan day.

A third observance follows a different clock altogether. Tamil Nadu’s Karthigai Deepam, with the Maha Deepam lit on the hill at Tiruvannamalai, is fixed by the Tamil solar month of Karthigai and the Krittika nakshatra rather than by the tithi, so it often falls on or near this full moon but not always on the same day. The snan date and Purnima timings on this page follow the sunrise rule for New Delhi.

Rituals of the day: snan, deep daan and katha

The day begins before dawn. Pilgrims bathe in the Ganga, the Yamuna, a sacred lake or any river or tirtha within reach, and those at home bathe with a little Ganga water added to the bucket while remembering the holy rivers. After the bath many devotees offer water to the rising Sun and worship the tulsi plant, and those who kept the month-long Kartik snan from Sharad Purnima onward complete their vow today.

Deep daan, the gift of lamps, is the signature act. Small clay diyas are placed on leaf boats and set afloat on the river, and lamps are lit at temples, at the tulsi, under the peepal and along the banks. In the evening many homes hold the Satyanarayan katha, the story of Vishnu as the lord of truth, with prasad of fruit and sweetened wheat or semolina. Some families fast until moonrise, offer arghya to the full Moon and only then take their meal.

Charity is woven through the day. Lamps, warm clothes, food and grain are traditionally given to priests, pilgrims and anyone in need, and ghats and temples organise community meals. At the great fairs, the bath, the lamp offering and the gift are often performed in one continuous sequence on the riverbank.

Traditional dos and don’ts for the full moon

Traditionally the day is kept sattvic: meat, alcohol, onion and garlic stay out of the kitchen in many homes, and the time is given to bathing, worship, charity and family. Many households make sure the tulsi lamp is lit at dusk, and those who cannot reach a river still light at least one lamp beside water at home. Those who fast choose its form by custom, from a full fast to a single fruit meal, and the elderly, unwell and expectant mothers are free to keep it lightly.

Crowded ghats call for ordinary care: bathe within marked areas, keep children close and avoid floating lamps where boats are moving. In years when a lunar eclipse falls on this full moon, families who observe sutak, the restricted period before an eclipse, schedule the bath, puja and meals around it according to their panchang.

Fairs and festivals along India’s rivers

Varanasi’s Dev Deepawali is the most famous sight of the night: the long crescent of ghats glows with lakhs of lamps, the Ganga aarti is performed on a grand scale and boats crowd the river. Upstream, the Garhmukteshwar Ganga fair in Uttar Pradesh draws large numbers for the full-moon bath, and in Rajasthan the Pushkar fair, which opened on Prabodhini Ekadashi, culminates with a dip in Pushkar lake.

In Bihar the Sonepur Mela at Harihar Kshetra, where the Gandak meets the Ganga, begins around this full moon and is one of the oldest and largest fairs in the country. Odisha remembers its seafaring past: before dawn on Boita Bandana families float miniature boats on rivers and ponds in memory of ancestors who sailed to distant lands to trade, and Cuttack holds the Bali Jatra on the banks of the Mahanadi.

In Tamil Nadu the Karthigai Deepam season lights up homes with rows of lamps and Tiruvannamalai with its hilltop beacon. Across Punjab and wherever Sikh communities live, gurdwaras are illuminated for Gurpurab, and in Gujarat Jain pilgrims climb Shatrunjaya for the first time since the monsoon.

Astrology of the Kartika full moon

Kartika takes its name from Krittika, the Pleiades, the nakshatra near which the Moon stands when it is full in this month. Krittika’s presiding deity is Agni, the god of fire, an apt patron for a festival of lamps, and its planetary lord in the Vimshottari scheme is the Sun. The nakshatra straddles sidereal Aries (Mesha) and Taurus (Vrishabha), so the full Moon is usually in one of these two signs, and Taurus is the sign of the Moon’s exaltation. The Sun stands opposite in Libra (Tula) or Scorpio (Vrishchika).

Purnima’s classical deity is Chandra, the Moon itself, and it belongs to the Purna group of tithis, whose name means “full”. The first half of every Purnima carries Vishti karana, or Bhadra, which muhurat practice avoids for auspicious beginnings, so families planning a ceremony on this day check when Vishti ends. Lunar eclipses can only occur at a full moon, and in some years one falls on Kartik Purnima itself.

Read together, the symbols are of fullness and fire: the Moon at its brightest in the fire-star of Agni, the Sun’s nakshatra lit by the Moon’s reflected light, and a month of lamps ending in a night when lamps fill the rivers.
