Adhika Jyeshtha Purnima is not an ordinary monthly full moon. It is the Purnima that falls inside an Adhika Maas — the intercalary lunar month inserted when the Hindu lunar calendar drifts out of step with the solar year. In 2026 that extra month is Jyeshtha, so the full moon within it is called Adhika Jyeshtha Purnima, Purushottam Purnima or Adhik Maas Purnima.
The Puranas name this extra month Purushottam Maas, the month claimed by Lord Vishnu as Purushottama. Classical texts describe the Purnima that crowns it as a day of heightened merit for snan, upavasa, japa, homa and charity. The main observance in 2026 falls on Sunday, 31 May, according to the udaya-tithi convention followed across much of India.
Whether you keep a simple home altar or join a live-streamed rite from afar, the day is observed through purification, Vishnu aradhana, sincere sankalpa and selfless giving — practices the tradition holds as especially fitting in Purushottam Maas.
What Is Adhika Jyeshtha Purnima?
The lunar year is shorter than the solar year. To keep seasons and festivals aligned, an extra month — Adhika Maas — is added roughly once every two to three years. When that month falls as Jyeshtha, its full moon becomes Adhika Jyeshtha Purnima.
Because Adhika Maas is also called Purushottam Maas, the Purnima inside it is widely known as Purushottam Purnima. The Skanda Purana, Padma Purana, Narada Purana and Bhavishya Purana speak of this day as a foremost occasion for worship, fasting and daan within the multi-year cycle. Vedic tradition describes japa, homa and Satyanarayan observance performed then as carrying far greater prescribed merit than the same acts on an ordinary day, and as suited to the purification of accumulated karma over the preceding years.
No weddings or other shubha samskaras are customarily fixed in Purushottam Maas; the whole month is set aside for penance, charity and inner discipline. The Purnima is treated as the spiritual crest of that month.
Adhika Jyeshtha Purnima 2026 Date and Muhurat
Key timings for the 2026 observance (IST) are as follows.
| Event | Timing |
|---|---|
| Purnima tithi begins | Saturday, 30 May 2026, 11:57 AM IST |
| Purnima tithi ends | Sunday, 31 May 2026, 2:14 PM IST |
| Main observance (udaya tithi) | Sunday, 31 May 2026 |
| Brahma muhurta (approx.) | 4:00 AM – 4:45 AM IST on 31 May |
Under the udaya-tithi rule — the civil day on which the tithi is current at sunrise — snan, daan, Vishnu puja and upavasa are kept primarily on Sunday, 31 May 2026. Diaspora devotees are generally advised to align the main fast and puja with that same civil date, even when local clock time differs from IST.
Auspicious windows traditionally favoured for bath and charity include the pre-dawn Brahma muhurta, the midday Abhijit muhurta, and the early evening before moonrise. Confirm the day’s tithi, sunrise and Rahu Kalam for your own city on the daily panchang, and use the muhurat finder if you need a named window for a specific undertaking.

Why Tradition Holds This Purnima Apart
Every Purnima carries lunar significance in the Vedic calendar. Adhika Jyeshtha Purnima is set apart for four classical reasons.
- It belongs to Vishnu. Purushottam Maas is described as governed by Lord Vishnu alone. The full moon that closes its arc is therefore treated as the peak of that Vishnu-centred month.
- Merit is spoken of as multiplied. Scriptures describe charity, mantra and fasting in this month — and above all on its Purnima — as yielding manifold prescribed phala compared with ordinary days.
- It is linked with the clearing of past burden. Texts specifically commend devout observance of Adhik Purnima — even a simple fast, prayer and gift — as a means of addressing karmas accumulated over roughly three years.
- It is uncommon. The combination appears only about once every two-and-a-half to three years. In 2026 it also falls on a Sunday, a weekday long associated with Surya and luminous observance.

Rituals for the Day
The classical sequence is simple and can be kept at home anywhere in the world.
1. Pre-dawn snan
Rise in Brahma muhurta on 31 May 2026. Bathe in a river, lake or sea if available; otherwise add a few drops of Ganga jal to bath water at home. Chant while bathing:
2. Altar and sankalpa
Clean the puja space. Spread a yellow or red cloth on a chowki; place murti or image of Vishnu and Lakshmi, with tulsi, fresh flowers, fruits, coconut and sweets as naivedya. Light a ghee deepam. Take sankalpa with water in the right palm — name, gotra if known, place, date and purpose — then release the water into a bowl.
3. Vishnu Sahasranama and Satyanarayan
Reciting the Vishnu Sahasranama is held supremely fitting. Where the full text is not possible, listening with attention while following the names is accepted practice. Satyanarayan puja and katha — with panchamrita offering — are among the most widely kept Purnima observances and are especially recommended on Adhika Jyeshtha Purnima. Family or neighbours may sit together for the katha.
4. Upavasa and Chandra arghya
A full fast from sunrise until after moonrise is the classical ideal; water-only or phalahar (fruits and milk) is accepted when health or work requires it. At moonrise, offer arghya — water with flowers and rice from a copper vessel — reciting Om Som Somaya Namah, then break the fast.
5. Japa and scripture
Preferred mantras include Om Namo Narayanaya, Om Namo Bhagavate Vasudevaya and Om Vishnave Namah, kept in counts of 108 or more. Guidance on posture and pronunciation is collected under how to chant a mantra. Reading even a short portion of the Bhagavad Gita, Srimad Bhagavatam or Vishnu Purana completes the day’s svadhyaya.
Deities, Daan and What to Avoid
Primary worship is of Lord Vishnu (Narayana) in his forms, together with Goddess Lakshmi. Lord Satyanarayan is the form most often invoked through the Purnima katha. Chandra receives arghya at moonrise. Shaiva households may also offer bilva, milk and water to the Shivalingam, as every full moon is sacred to Shiva.
Daan is the practice the scriptures stress most strongly in Purushottam Maas. Clothes, food grains, sesame, ghee, jaggery, fruits, footwear, or support to temples and institutions that serve the poor are all traditional gifts. Sponsoring a homa as ritual daan is a recognised form of giving when one cannot visit a temple in person. Rites that invoke Vishnu’s protective chakra, such as the Sudarshana Homa, or the hymn-based Narayana Sukta Homa, are among those the house performs at the Yagna Ashram and telecasts live.
What tradition advises against on the day: non-vegetarian food, alcohol and heavy tamasic fare; argument and harsh speech; waste of food; and breaking a sankalpa once taken. The same texts that magnify meritorious acts treat careless conduct on this tithi as leaving a sharper imprint — so the day’s energy is used deliberately.
Purushottam Maas and the Place of This Purnima
Adhika Jyeshtha Purnima is best read as the crown of the whole Purushottam Maas of 2026, not as an isolated date. The extra Jyeshtha month is a full lunar span given to worship and restraint; 31 May 2026 is described as its highest point. Beginning observances earlier in the Adhika month and building toward the Purnima is the classical ideal; beginning on the Purnima itself is still held as complete and valid.
Festival and tithi dates through the year, including other Purnimas, can be checked on the festival calendar. For the wider catalogue of fire rituals grouped by purpose, see all homas.
On 31 May 2026, from Brahma muhurta to moonrise, the traditional path is straightforward: bathe, take sankalpa, worship Vishnu and Lakshmi, keep the fast as strength allows, chant, give, and offer arghya to Chandra. Devotees who wish a priest-led fire rite may request one from the ashram in Pollachi, Coimbatore District, performed to Agama discipline and telecast live, with the day’s merit dedicated under their sankalpa.
