The full moon of Bhadrapad month (the last tithi of the Shukla paksha) — Saturday, 26 September in 2026. "Bhadrapad Purnima" and "Proshthapadi Purnima" (Sanskrit Proushthapadi) are both commonly used names for the same day. On this day, the general Purnima practices of moon worship and Satyanarayan puja are observed. This tithi falls right next to Pitru Paksha/Mahalaya — Mahalaya begins the very next day — and a Purnima-shraddha is performed on this day itself. However, the formal fifteen-tithi Pitru Paksha begins from Pratipada, not from Purnima.
Hindu months are named after the nakshatra the moon occupies on that month's Purnima (for example, Chaitra corresponds to the Chitra nakshatra) — the name "Bhadrapad" is believed to come from the Bhadrapada (Purva/Uttara) nakshatra. This year (2026), the moon is indeed in Purva Bhadrapada nakshatra on this Purnima — directly visible in the panchang's own record.
The exact relationship to Pitru Paksha (the central point of this page): Three independent sources consistently state that the formal Pitru Paksha begins from Pratipada and runs fifteen tithis through Sarvapitri Amavasya; the "Purnima-shraddha" performed on Bhadrapad Purnima is not a formal part of Pitru Paksha — it is a separate rite performed for ancestors who died on the Purnima tithi specifically, one that happens to be a parvan shraddha immediately preceding/adjacent to Pitru Paksha. The panchang itself shows this too — Proshthapadi Purnima falls on 26 September, while Mahalaya begins (Pratipada) on 27 September — distinct dates. Many popular articles oversimplify this as "Pitru Paksha begins on this very day" — which is misleading; clarifying this exact distinction is the main purpose of this page.
Satyanarayan puja is an extremely common practice performed across India (including Maharashtra) on any Purnima, Ekadashi, or other auspicious occasion — Bhadrapad Purnima is no exception, but it is not a distinguishing feature of this particular tithi.
Anant Chaturdashi falls the very day before (25 September), marking the conclusion of Ganeshotsav with the public immersion of the idols — the Ganpati immersion does not happen on Bhadrapad Purnima itself; it is already concluded the day before.
In Gujarat, this tithi ("Bhadarvi Poonam") sees a major three-day fair (Teras-Chaudas-Poonam) at the Ambaji Shaktipeeth temple, with lakhs of devotees undertaking a pilgrimage on foot — this is an example from outside Maharashtra, not a local custom.
No single, universally agreed-upon central legend for this day was found. The most frequently cited legend directly tied to Bhadrapad Purnima is the Uma-Maheshwar vrat katha — but sources diverge on both its tithi and its central figure, so this legend is presented here as a secondary, alternative element.
The shared core is this — a deity (Vishnu, in both versions found) loses his prosperity/grace due to a curse; as penance, he is instructed to worship Shiv-Parvati (Uma-Maheshwar) on Bhadrapad Purnima; after performing the vrat, everything lost is restored.
In one version, sage Durvasa gifted Vishnu a garland of bel leaves he had received from Shiv; when Vishnu placed it around the neck of his mount Garuda, Durvasa considered this disrespectful and cursed Vishnu — that he would lose the company of Lakshmi, the Kshirasagar (ocean of milk), and Shesha. As penance, Durvasa himself is said to have prescribed the Uma-Maheshwar vrat on Bhadrapad Purnima; after performing it, Vishnu regained everything. In another version, Vishnu is said to have worshipped Shiv and the Moon as penance for the curse, which is how the tradition connects to Satyanarayan vrat — the details differ slightly, but the core (curse → penance vrat) is consistent.
According to one older, unclear-origin reference, the central figure in this vrat is not Vishnu but Indra — with a mention that Indra performed this vrat to regain Airavata/his throne in Indraloka; this could not be independently verified. The tithi itself is also disputed — one claim holds that the Narada Purana places this vrat on Bhadrapad Purnima, while the Bhavishya Purana places the same vrat on Margashirsh Shukla Tritiya (an entirely different month/tithi) — this claim could not be verified from the primary source page directly, so it is not stated as settled here.
General devotees perform Satyanarayan puja, offer arghya to the moon, observe a fast, and give charity — as on any Purnima. Those whose ancestors died on the Purnima tithi perform their Purnima-shraddha (a parvan shraddha) on this very day — for father, grandfather, great-grandfather, and maternal-side ancestors as well. Some traditions (mainly in North Indian/Hindi-language religious media) also mention devotees observing the Uma-Maheshwar vrat — no evidence was found of this being practised under this name in independent Marathi sources in Maharashtra, so it is not presented here as a mainstream Maharashtra practice.
A morning bath (at a sacred river/tirtha if possible) is customary. Satyanarayan puja is a general Purnima practice — panchamrit-snan, listening to/reading the katha, and offering naivedya; the detailed ritual is given on the Satyanarayan Pooja page and not repeated here.
By tradition, for those whose ancestors died on Purnima, the Purnima-shraddha is generally performed in the parvan-shraddha style — one common account gives the window as the Kutup/Rohin muhurat through the afternoon period. The exact procedure can vary by family/kulachar, and the exact timing varies by city/year, so timing belongs on the 26 September day page rather than here, while the exact rite is best confirmed with your family priest.
In the evening, moonrise darshan and arghya are offered. Charity — feeding the needy, and offerings/dakshina to Brahmins — is considered auspicious on both counts, Purnima and its proximity to the ancestor rites.
According to one account, in the secondary, disputed-tithi Uma-Maheshwar vrat, the sequence given is: a bath at Brahma muhurat → worship of Shiv-Parvati (with bel leaves) → an all-night vigil → feeding Brahmins/charity; this sequence can vary by tradition/kulachar. Some accounts also mention performing this for fifteen consecutive years before a concluding udyapan.
Panchamrit (milk-curd-ghee-honey-sugar) and the usual materials for Satyanarayan puja (kalash, rice, banana-stalk pillars, naivedya); water/milk and a copper vessel for moon-arghya; tarpan materials for ancestors (sesame seeds, barley, darbha grass, water); bel leaves and a Shiv-Parvati image/idol for those observing the Uma-Maheshwar vrat; lamps, incense, and materials for charity.
The general Purnima-fasting practice applies — light snacks or fruit; one source mentions avoiding grains and salt. The strictness varies by household/local tradition. After the Satyanarayan puja, it is common to take the shira/panchamrit prasad.
The Satyanarayan katha/aarti is part of the general Purnima practice — for the full text, see the Satyanarayan Pooja page; it is not repeated here. An Uma-Maheshwar stotra is found to exist by title, but its text and rights have not been verified.
In Gujarat, the Ambaji Shaktipeeth temple holds the Bhadarvi Poonam fair — a three-day (Teras-Chaudas-Poonam) event with lakhs of devotees on a foot pilgrimage; this is not a Maharashtra custom, and is noted here only for comparison/context. One source mentions that during the varshavas period, Buddhist devotees gather on this Purnima to take the eight precepts (ashtashila) and listen to dhamma — this has not been independently corroborated. No distinct Maharashtra-specific custom or fair was found in this research — this page is built primarily around the general moon/Satyanarayan worship and clarifying the Pitru Paksha proximity.
Don't take it as settled that "Bhadrapad Purnima is the first day of Pitru Paksha" — the formal Pitru Paksha begins from Pratipada (27 September); today is the day of Purnima-shraddha, immediately preceding it. The shraddha muhurat (Kutup/Rohin/afternoon period) varies by city/panchang — see the day page for the exact timing. Household shraddha ritual practice varies by family tradition — confirm with your priest/family custom.
