Some Hindu years feel longer because they are. Roughly once every thirty-two to thirty-three months the lunisolar calendar inserts a thirteenth month so that lunar months stay aligned with the solar year. In 2026 that intercalary month is Adhika Jyeshtha, running from 17 May to 15 June, and tradition knows it as Purushottam Masa or Mal Masa.
The lunar year is about 354 days; the solar year about 365. The shortfall of roughly eleven days accumulates until it equals a full lunar month, at which point calendar-keepers add an extra masa. That month carries no Surya Sankranti—the Sun does not enter a new rashi within it—and classical practice therefore sets it apart from ordinary material muhurtas.
What follows explains the astronomy, the Puranic naming as Purushottam Masa, the 2026 dates, the observances tradition recommends and those it asks devotees to defer, so that the month can be kept with clarity whether one is in India or abroad.
What Adhika Masa Is, and Why 2026 Has Two Jyeshthas
Adhika Masa is an intercalary lunar month inserted to correct the drift between the Chandra mana (lunar) and Saura mana (solar) years. Over about 2.7 to 3 years the accumulated gap reaches one full lunar month of twenty-nine or thirty days; the extra month is then placed before its nija (regular) counterpart of the same name.
In 2026 the extra month is Adhika Jyeshtha (also called Pratham Jyeshtha). It is followed at once by Nija Jyeshtha. The year therefore belongs to a thirteen-month Hindu calendar span within the Parabhava Nama Samvatsara. Because no solar ingress falls inside the adhika month, you can confirm the surrounding Sankranti pattern on the house’s Sankranti transit guide and read the day’s tithi and nakshatra on the daily panchang.
From the Vedic standpoint the month is not treated as a time for launching houses, marriages or new firms. It is treated as time set aside for devotion, study, dana and ancestral remembrance—the work the tradition assigns when the calendar itself steps outside ordinary sankranti rhythm.
Key Dates of Adhika Masa 2026
Under the panchangs commonly followed in North India and in Gujarati, Marathi, Kannada and Telugu usage, the principal markers of Adhika Jyeshtha 2026 are:
| Event | Date |
|---|---|
| Adhika Masa begins | Sunday, 17 May 2026 |
| Purushottam Purnima (full moon) | Sunday, 31 May 2026 |
| Adhika Masa Amavasya / month ends | Monday, 15 June 2026 |
Purushottam Purnima is traditionally regarded as the high point of Vishnu-centred observance within the month. Adhika Amavasya is widely kept for pitru tarpan, shraddha-related charity and quiet ancestral prayer. Festival dates later in 2026 shift by about a lunar month relative to non-adhika years; the festival calendar is the practical place to check those moved tithis.

Why the Extra Month Is Called Purushottam Masa
Classical telling, preserved especially in the Skanda Purana tradition, explains the name. Each of the twelve ordinary months had a presiding deity and a settled place in the round of samskaras and festivals. The orphaned thirteenth month had none. People called it Mal Masa—the “impure” or leftover month—and postponed weddings, griha pravesh and new ventures until it had passed.
The month is said to have approached Vishnu and asked for shelter. Vishnu, as Purushottam—the Supreme Person—took the month under His own care and named it Purushottam Masa. From that dedication onward, tradition holds the month as belonging to the Lord rather than to worldly milestones: suitable for japa, puja, homa, vrat and dana, and unsuitable for the muhurtas of marriage and material beginning.
That distinction still guides practice. Spiritual acts are encouraged; social and commercial inaugurations are deferred until Nija Jyeshtha and the months that follow.
What Tradition Emphasises in This Month
Several features make Adhika Jyeshtha 2026 distinctive in the classical view:
- Double Jyeshtha. Jyeshtha appears twice—first as the adhika month, then as the nija month—so the season associated with ancestral duty and summer austerity is extended.
- Absence of Surya Sankranti. The defining astronomical mark of adhika masa is that the Sun does not change rashi inside it. The month sits in a calendrical pause between ingresses.
- Pitru-oriented days. Amavasya within Purushottam Masa is traditionally used for tarpan and charity aimed at the pitru line. Devotees who wish to see whether a chart is described as carrying Pitru or related doshas can use the free dosha check as a starting reference before speaking with a priest or astrologer.
- Vishnu-centred sadhana. Japa of names of Vishnu, reading of the Bhagavata, tulsi archana and Ekadashi vrata are the observances the Puranic stream repeatedly names for this month.
Scripture and acharya tradition speak of heightened regard for punya accumulated through sincere worship in Purushottam Masa. The house presents that as the classical framing—not as a personal assurance of any worldly result.
Observances to Keep, and Acts Tradition Asks You to Defer
Personal practice during Adhika Masa is simple and steady rather than elaborate. Common household observances include:
- Morning deepa, tulsi offering and japa of Om Namo Bhagavate Vasudevaya, often in a count of 108.
- Daily or regular reading of the Srimad Bhagavatam, even for a short sitting.
- Maintaining an akhanda deepa (continuous ghee lamp) in the puja room for the span of the month, where it is safe to do so.
- Dana of food, clothes, books or funds, especially toward feeding and education.
- The two Ekadashis that fall inside the month, kept with fasting and Vishnu smaranam as one’s health allows.
- Tulsi archana while reciting the Vishnu Sahasranama.
Acts ordinarily postponed until after 15 June 2026 include marriage and engagement rites, griha pravesh, launch of a new business or major contract, and—in many families—hair-cutting as a form of tapas. Sattvic diet, restraint in speech and unbroken daily worship are urged so that the month’s character as a Vishnu-dedicated interval is not diluted.
For muhurta questions outside the adhika window, the muhurat finder helps locate ordinary auspicious spans once Nija Jyeshtha is under way.
Homas and Sevas Aligned with Purushottam Masa
Because the month is dedicated to Vishnu as Purushottam, fire rites and sevas that invoke Narayana, the Vishnu suktas and the Sudarshana are the forms tradition most naturally pairs with it. At AstroBhava such rites are performed by named priests at the Yagna Ashram in Pollachi, Coimbatore District, and telecast live to devotees who cannot be present in person.
The Narayana Sukta Homa offers the Vedic Narayana Sukta into the fire—the hymn that praises Narayana as the all-pervading sustainer. It is a direct liturgical match for a month the Puranas place under Vishnu’s own care. The Sudarshana Homa is kept where the tradition turns to the Sudarshana anga of the Lord. Broader Vishnu-facing and devotion-oriented options are grouped under the spiritual growth homa catalogue when a priest recommends a different anga or sukta.
Japa anushthana of Vishnu mantras, tulsi archana and, on Adhika Amavasya, pitru tarpan remain the complementary personal or priest-led acts. The house performs what tradition prescribes for Purushottam Masa; it does not claim any fixed worldly result from the rite.
