Maghi Purnima falls on Magh Shukla Purnima — the day marking the end of the Magh Snan month and Kalpvas. River bathing, worship of Vishnu/Madhav and Surya, and charity all hold special importance on this day. In 2026, this tithi falls on Sunday, 1 February. Two separate occasions — Lalita/Shodashi Jayanti and Sant Ravidas Jayanti — are also co-observed on the same tithi.
The merit of bathing in sacred rivers and giving charity through the entire month of Magh is said to reach completion on this Purnima — some sources equate this merit to that of an Ashwamedha yajna. The name "Maghi"/"Magh" is said to come from the Magha nakshatra, since the full moon draws near this nakshatra.
Kalpvas — the practice of staying in tents at the Prayagraj Sangam for a month of Vedic study and austerity — also concludes on this very Purnima. Since this is chiefly a North Indian tradition, it's noted here as background, without a Maharashtra-centric emphasis.
Sesame's six uses — in bathing, in ubtan paste, in havan, in consumption, in charity, and in offerings — are said to destroy sin.
Three separate occasions are also co-observed on this same tithi — each is a distinct facet, and should not be merged:
Two different legends are found for Maghi Purnima — neither should be presented as this tithi's one authentic story.
The first, the Shubhavrata Brahmin-Narmada mahatmya legend, is fundamentally a story about the merit of Magh bathing, not a Purnima-specific vrat-katha. The second is a "thirty-two Purnima" vrat legend about a childless Brahmin couple — worshipping Goddess Kali and observing a sixteen-day vrat that brought their son long life — but this is a generic Purnima-vrat legend that recurs across many Purnimas, not specific to Magh.
Both legends are recorded separately here; neither is presented as "the official legend of Maghi Purnima."
Devotees who bathe and give charity — bathing before dawn in a sacred river (or at home with Ganga-mixed water) and giving alms. Kalpvasis — those who stay a month at the Prayagraj Sangam (chiefly a North Indian tradition). Farming communities, who follow the custom of offering new jowar/grain to the deity before consuming it themselves. Lalita/Shakta worshippers and Ravidas devotees also keep their own separate observances on this same tithi.
No independent, widely accepted udyapan ritual specific to Maghi Purnima was found.
Ganga water or river water, an image of Vishnu/Madhav and Surya, sesame (for bathing, ubtan, havan, charity), lamps-oil-wick, food grain-clothing-jaggery-ghee-blankets for charity, and ears of new jowar/grain (for the agricultural rite).
Fasting isn't mandatory for everyone — the main emphasis is on bathing and charity. For those who do fast, a light sattvic diet or a fruit-only diet is common — this varies by household and local tradition.
By tradition, the Vishnu chant "Om Namo Narayana" is associated with this day.
Konkan/Kunbi-Warli new-grain custom (limited-source): according to limited sources, Maharashtra — especially the Konkan belt — has an agricultural custom expressing gratitude for the new harvest on Magh Purnima: the Kunbi community is said to worship seven stones; the Warli community is said to install the deity 'Narayan' on the rice heap and dance around it; farmers more generally are said to worship five ears of new jowar.
This custom should not be called "Navann Purnima" — that name is established as belonging to Kojagiri/Sharad (Ashwin) Purnima. Magh's new-grain custom is a parallel, separate practice.
Maghi Wari (Pandharpur) — adjacent, but a different tithi: the Maghi Wari pilgrimage to Pandharpur falls on Jaya Ekadashi (Magh Shukla Ekadashi, 29 January in 2026) — three days before this Purnima, not on the Purnima itself. Maghi Wari and Maghi Purnima shouldn't be treated as the same thing; full detail is on the Jaya Ekadashi page.
