Kojagiri Purnima is the night of Ashwin Shukla Purnima — devoted mainly to goddess Lakshmi (alongside Indra on Airavata and King Bali) and the full moon. The name "Kojagiri" comes from the Sanskrit "Ko jaagarti?" ("Who is awake?") — by tradition, Lakshmi wanders the earth this night asking exactly that, granting wealth and prosperity to those who stay awake in devotion. An all-night vigil, masala milk simmered under moonlight, and Ashwin's clear autumn moonlight are this night's signature features. This year (2026): Sunday, 25 October.
This is the Purnima of the autumn season, right at the end of the monsoon — the sky is clear and the moonlight bright, making this a moon-centred festival. The moon is held to be full with all sixteen kalas (phases) on this night, and its rays are believed to carry amrit (nectar) down to earth — which is why milk or kheer is left out under the open moonlight before being taken as prasad.
This night is linked to the period when Lakshmi is said to have emerged from the Samudra Manthan (the churning of the ocean); a wish for wealth and prosperity lies at its heart — coming roughly two weeks before Diwali, it feels like the start of the "Lakshmi season." A broader Indian belief also holds that Krishna performed the raaslila with the gopis in Vrindavan on this same Sharad Purnima night — though Maharashtra's Kojagiri emphasis remains centred on Lakshmi and the moon.
Rice, nachni, and vari — the new season's grain — arrive around this time, giving rise to Navanna Purnima (nav + anna, "new grain"), when the first offering of the new harvest is made; it's observed in Konkan and rural areas alongside Kojagiri.
Two stories are mainly linked to Kojagiri; both share a common thread — that keeping an all-night vigil in devoted worship of Lakshmi on Ashwin Purnima removes poverty and brings wealth and prosperity, since Lakshmi wanders about asking "who is awake."
Version A — the Valit Brahmin and the Naga maidens. A learned but poor Brahmin from the land of Magadh, stung by his wife's taunts, resolves to seek Lakshmi's favour and goes into the forest. There, Naga maidens of serpent lineage are observing a Lakshmi vrat on Ashwin Purnima; they give him prasad and play dice (dyuta) with him, and by Lakshmi's grace he receives abundant wealth and gold. The custom of playing games through the Kojagiri night is traced to this story.
Version B — the generous king, the queen, and the iron idol of Alakshmi. A generous king once buys an iron idol of Alakshmi (the goddess of poverty); Lakshmi, unable to bear living alongside Alakshmi, weeps. The queen performs Lakshmi puja on Ashwin Purnima and keeps vigil all night; by the radiance of her devotion, the iron idol melts, and prosperity comes to the kingdom.
According to English Wikipedia, this night is described in the Brahma, Skanda, Brahma Vaivarta, and Linga Puranas.
Families and friends gather at night for the vigil, songs, conversation, and masala milk — in Maharashtra, this is a social, family-gathering festival. Devotees of Lakshmi keep a threefold vrat of fasting, worship, and vigil. Farming and rural families also observe this day for its Navanna connection. In Bengal-Assam it's Kojagari Lakshmi puja; in Odisha, Kumar Purnima (where unmarried girls keep a vrat for a suitable husband); in Gujarat, garba is celebrated.
The order and details vary by household and local tradition — the following is a researched general form.
No solid reference for a separate, formal concluding rite (udyapan) was found.
Images of Lakshmi (and Indra-Bali), lamps or sky-lanterns with oil-wicks, flowers, garlands, rangoli materials, milk with saffron-almonds-pistachios-cardamom-nutmeg-sugar (masala milk), a silver, glass, or clay vessel (for the moonlight), naivedya (kheer or new-grain dishes), and incense.
A daytime fast followed by masala milk or kheer as prasad after the night's vigil is the general practice; its strictness varies by household and local tradition. New-grain dishes (rice, kheer) are also made for the Navanna connection.
An aarti and Lakshmi mantra/stotra are recited on this night, invoking Lakshmi's presence and her blessing. The familiar opening line of the Mahalakshmi aarti: "Jai Devi Jai Devi Jai Mahalakshmi" ("Victory to you, O Mahalakshmi"). Only the meaning and opening line are given here, not the full aarti text.
The Purnima tithi runs from 11:56 AM on 25 October to 9:41 AM on 26 October. Since 26 October has Purnima at sunrise, Navanna Purnima (and Valmiki Jayanti) fall on that day. Kojagiri, however, is a vigil-centred night festival, so it's observed on the night when Purnima is actually running — that is, the night of 25 October.
Future years: the tithi (Ashwin Shukla Purnima) stays the same; the Gregorian date is set by that year's panchang.
