Krishna Janmashtami

Krishna Janmashtami marks the birth of Krishna on the eighth lunar day of the dark fortnight of Bhadrapada, which falls in August or September. The Bhagavata Purana places that birth in the dead of night, in Kansa's prison at Mathura. So the festival is kept awake until midnight, with fasting through the day, kirtan through the evening, and an abhishek of the infant Krishna at the stroke of the hour.

Almost every question people ask about the day comes back to that midnight. Why the vigil, why the fast runs so long, why one family in a street keeps it a day before another. Here is the whole thing, from the verses outward.

What does the Bhagavata Purana say about Krishna's birth?

The account sits in the third chapter of the tenth canto, titled the birth of Lord Krishna. It opens with the sky rather than with the child.

Bhagavata Purana 10.3.1 to 10.3.5 describes the hour: the constellation Rohini risen, none of the constellations fierce, the rivers running clear, the wind carrying fragrance, and the minds of good people at ease for the first time under Kansa. Kinnaras and Gandharvas sing. Only after five verses of that setting does the text come to the birth itself.

Then 10.3.8, the verse the entire festival hangs on:

nishithe tama-udbhute jayamane janardane devakyam deva-rupinyam vishnuh sarva-guha-shayah avirasid yatha prachyam dishindur iva pushkalah

"At the dead of night, when the darkness was dense, Vishnu appeared from Devaki, like the full moon rising in the east."

Bhagavata Purana 10.3.8

The child appears first in four-armed Vishnu form, with conch, disc, club and lotus, which is how Vasudeva and Devaki understand who their son is (10.3.9-10). At their prayer he takes the form of an ordinary infant (10.3.46). Vasudeva then carries him out of the prison to Gokula, and at that same moment Yogamaya is born as the daughter of Nanda's wife (10.3.47). The exchange in the night, the river, the sleeping guards: all of it is this chapter.

Two chapters later, Nanda holds the birth ceremony in Vraja (10.5). That celebration is the origin of Nandotsav, which Braj still keeps the day after Janmashtami.

Why is Janmashtami celebrated at midnight?

Because of one word in 10.3.8. Nishitha means the deep-night watch, the period around the midpoint between sunset and sunrise, and the verse uses it as the hour of the appearance.

That is why panchangs publish a nishita puja muhurat for Janmashtami rather than a morning one, and why it is a narrow window, usually about forty-five minutes. In 2026 the nishita window for Delhi runs from roughly 11:57 pm on 4 September to 12:43 am on 5 September. It shifts by city, because it is calculated from local sunset and sunrise, not from a clock.

The rest of the night's shape follows from it. The fast is not broken at sunset because the reason to fast has not arrived yet. The vigil, jagarana, exists so that no one sleeps through the moment. The abhishek is done on the infant form, not the adult, because what is being marked is a birth.

What is the tithi, and why does the date move?

The tithi is ashtami, the eighth lunar day, in krishna paksha, the waning fortnight. In the purnimanta calendar used across north India that fortnight belongs to Bhadrapada. In the amanta calendar used in Maharashtra, Gujarat, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Assam and Bengal, the very same fortnight belongs to Shravana.

So a Delhi panchang says Bhadrapada krishna ashtami and a Pune panchang says Shravana krishna ashtami, and they are pointing at the same night. Only the month naming differs, not the day.

The Gregorian date moves because the Hindu calendar is lunisolar. Twelve lunar months run about eleven days short of a solar year, so a festival drifts earlier each year until an extra month, adhika masa, is inserted and it jumps forward again. Janmashtami swings across a window from early August to early September. It was 26 August in 2024, 16 August in 2025, 4 September in 2026, and 25 August in 2027.

A tithi also begins and ends at a clock time rather than at midnight, which is the second reason the calendar looks odd. In 2026 ashtami begins at 02:25 on 4 September and ends at 00:13 on 5 September, so it covers one midnight and misses the next.

Why do smarta and Vaishnava households sometimes keep it a day apart?

They apply different tests to the same tithi.

Most years the two tests give the same answer and nobody notices. In 2025 they did not. Ashtami began at 11:49 pm on 15 August, and Rohini nakshatra did not begin until 17 August, so the smarta rule pointed at 15 August and the Vaishnava rule at 16 August. The Government of India gazetted holiday list took 16 August, and titled the entry Janmashtami (Vaishnava).

Kerala adds a third path. There the day is Ashtami Rohini, fixed by the solar month of Chingam together with Rohini nakshatra, so it can fall a day or two away from the rest of the country and occasionally further.

None of this is a dispute. Each tradition is honouring a different half of the same verse, the tithi or the star.

How is Janmashtami observed?

The day has a fixed arc almost everywhere, whatever the local name.

The fast. Most people drop grains and lentils and eat phalahar: fruit, milk, curd, nuts, potato, sabudana, and singhara or kuttu flour in place of wheat. Dhaniya panjiri, ground coriander seed with ghee and sugar, is the north Indian Janmashtami prasad precisely because it contains no grain. Nirjala, going without water, is a personal choice and is never expected.

The jhanki. Households and temples build tableaux of scenes from Krishna's life, the prison, the crossing of the Yamuna, Gokul, the butter pots. A cradle is set up for the infant and rocked. In Tamil Nadu women press tiny footprints in wet rice flour from the threshold to the altar, so the child is welcomed all the way in.

The night. Kirtan, bhajans and readings from the tenth canto carry the evening. The Hare Krishna maha mantra is the one chanted most widely. Rasa lila troupes perform in Braj, and Manipur keeps night-long kirtan at the Shree Shree Govindajee temple in Imphal.

Midnight. The abhishek is done at the nishita window with panchamrit, then the deity is dressed, the aarti is sung and the conch is blown. Makhan mishri, kheer, peda and fruit are offered.

The next day. Parana breaks the fast once ashtami and Rohini have passed, and the celebration turns outward into Nandotsav and Dahi Handi.

What is Dahi Handi, and what is Nandotsav?

Both belong to the day after, and both are the joy of Vraja rather than the solemnity of the prison.

Nandotsav is Nanda Baba's own celebration of the birth, kept on Bhadrapada navami at Gokul and Nandgaon. Sweets and gifts are given away, exactly as 10.5 describes Nanda giving to everyone present whatever they asked. The line sung all day is Nand ke anand bhayo, jai Kanhaiya Lal ki.

Dahi Handi, also called Gopalkala, is Maharashtra's version of the same joy. A clay pot is slung thirty or forty feet above a street, and teams called govinda pathaks build a human pyramid to reach it. The pot holds gopalkala, curd mixed with poha, coconut and sugar.

It is a re-enactment of a specific verse. At Bhagavata Purana 10.8.30 the gopis complain to Yashoda that when the milk and curd are hung too high, Krishna and Balarama pile up planks and turn the grinding mortar upside down to climb to it. The pyramid in a Mumbai street is that scene, staged once a year at scale. Kerala keeps the same idea as Uriyadi, where a pot of butter, seedai and murukku is hung and struck at.

How do Mathura, Vrindavan and Dwarka keep it?

Braj is where the day is largest, and each town keeps a different piece of it.

Mathura keeps the birth. At Shri Krishna Janma Bhoomi, the site held to be Kansa's prison, the night runs on abhishek, jhankis, rasa lila and kirtan straight through to the midnight hour, with pilgrims arriving from across the country. Dwarkadhish temple in the old city keeps its own crowded programme.

Vrindavan keeps the darshan. Its most distinctive custom belongs to Banke Bihari, where mangala aarti is not performed on ordinary days at all, because Bihari ji is understood to wake late. Once a year, on Janmashtami, the mangala aarti is held, at about two in the morning, and hundreds of thousands of devotees come for it. Entry has to be limited. ISKCON Vrindavan runs its own maha abhishek and all-night kirtan a short distance away.

Gokul and Nandgaon keep the aftermath, so their peak is Nandotsav the following day rather than the midnight itself.

Dwarka keeps Krishna the king rather than the child. At the Dwarkadhish temple in Gujarat the night ends in a midnight aarti, and the state calls the festival Satam Atham.

Where does Janmashtami sit in the Radha Krishna year?

Fifteen days before Radhashtami. Janmashtami is the eighth day of the waning fortnight and Radhashtami the eighth of the waxing fortnight of the same lunar month, so Radha's appearance always follows Krishna's by a fortnight, every year. Barsana is to Radhashtami what Mathura is to Janmashtami.

The two days also differ in character. Janmashtami is kept at midnight and is a gazetted holiday across India. Radhashtami is usually kept at midday and is a Braj and Vaishnava observance rather than a national one, because the sampradayas differ on Radha's theological position. Who Radha is works through that carefully, and the birth of Srimati Radharani sets out what each text actually says about her appearance.

For everything else in the year, the festivals hub has the full calendar with the tithi for each. If you arrived with a doubt rather than a date, questions answers the common ones with sources, including why Krishna is shown blue and why Krishna did not marry Radha.
