Once every two to three years the Hindu lunar calendar inserts an extra month — an Adhika Maas — so that the shorter lunar year stays aligned with the solar year. In 2026 that month is Adhik Jyeshtha Maas, running from 17 May to 15 June. Nested inside it is the Krishna Paksha Ashtami dedicated to Lord Kaal Bhairava, known to devotees as Adhika Kalashtami.
This is not the ordinary monthly Kalashtami. It falls inside Purushottam Maas, the month the Padma Purana and Skanda Purana treat as governed by Lord Vishnu in His Purushottama form, when acts of dharma, charity, japa and homam are held to carry multiplied spiritual merit. The date, the tithi window, and the classical way of keeping the vrat are set out below.
Whether you are observing from India or abroad, the Ashtami is fixed by the lunar tithi. Confirm the local evening with the daily panchang for your city before you begin the puja.
What Is Kalashtami?
Kalashtami — also written Kala Ashtami or Kaala Ashtami — is observed on the Ashtami tithi of Krishna Paksha, the waning fortnight, every lunar month. The day is dedicated exclusively to Lord Kaal Bhairava, the fierce and protective form of Lord Shiva who is described in the scriptures as the master of time (kaal) and the guardian of Kashi.
Among the twelve monthly Kalashtamis, the observance in Margashirsha (often called Kalabhairav Jayanti) is traditionally the most exalted. An Ashtami that falls inside an Adhika Maas is rarer still: it appears only when the panchanga has inserted the extra month, roughly once in thirty-two months or more. Adhika Kalashtami May 2026 is that occurrence for the present cycle.
The word kaal means both time and death. Classical descriptions present Kaal Bhairava as the one who holds authority over the cycles of birth, karma and liberation, and as the Kotwal — the chief guardian — of Kashi. The monthly vrat is the regular means by which householders keep that connection; the Adhika observance simply places the same vrat inside the merit-amplifying month of Purushottama.
Date and Ashtami Tithi Timings
Adhika Kalashtami falls on Monday, 8 June 2026. It is the Krishna Paksha Ashtami of Adhik Jyeshtha Maas. Devotees often still call it “Adhika Kalashtami May 2026” because the Adhika month itself begins in May.
Ashtami tithi timings in Indian Standard Time:
| Event | Timing (IST) |
|---|---|
| Ashtami tithi begins | 03:24 AM on 8 June 2026 |
| Ashtami tithi ends | 03:23 AM on 9 June 2026 |
| Recommended puja window | Evening and night of 8 June 2026 |
Tradition places Kaal Bhairava worship in the nocturnal hours. The most commonly kept window is from Pradosh Kaal (dusk) through Nishita Kaal (around midnight). Adjust to local sunset if you are outside India, and cross-check the tithi on the tithi calendar or your city panchang so that the sankalpa is taken while Ashtami is still running.
Why Adhika Kalashtami Is Rare: Adhik Jyeshtha Maas
A lunar year is about 354 days; a solar year is about 365. The gap of roughly eleven days accumulates, and after about thirty-two months the panchanga inserts a thirteenth month — Adhika Maas — so the lunar months do not drift away from the seasons. In 2026 that extra month is Adhik Jyeshtha, from 17 May to 15 June.
Adhik Maas is also called Purushottam Maas or Mal Maas. The Padma Purana and Skanda Purana assign it to Lord Vishnu as Purushottama and state that dharma, dana, japa and ritual performed in this month carry multiplied punya. It is for that reason that an Ashtami of Kaal Bhairava falling inside Adhik Maas is treated as a compounded observance: the regular monthly dedication to Bhairava is kept inside the month whose every act of worship is classically described as magnified.
The alignment does not return every year. Missing the 2026 window means waiting for the next Adhika Maas cycle. For a wider view of festival and tithi dates across the year, the festival calendar lists the principal observances month by month.
Lord Kaal Bhairava: Deity of the Vrat
Lord Kaal Bhairava is worshipped as the compassionate protector of sincere devotees and as the guardian who cuts the bonds of fear and ignorance. Iconography shows Him with four arms, holding trishul, damaru, pasha and kapala; He wears serpents and a garland of skulls, and His vahana is the black dog. His dark complexion is read as the depth of time itself.
As Kotwal of Kashi He is held to preside over the passage of every soul through that city. The monthly Kalashtami vrat — fasting, lamp offering, mantra and, where possible, feeding a dog — is the householder’s ordinary means of approaching Him. On Adhika Kalashtami the same vidhi is followed, with the added awareness that the day sits inside Purushottam Maas.
In jyotisha, Kaal Bhairava is closely associated with the discipline and time-bound karma of Shani. Devotees who are tracking Saturn’s transit or asking whether Sade Sati is running in the chart often keep this Ashtami with particular care, alongside other planetary observances listed under planetary homas. Tradition prescribes the worship; it does not guarantee a particular worldly result.

Puja Vidhi and Mantra on Adhika Kalashtami
The classical outline of the day is simple and nocturnal. Clean the altar; place an image or murti of Kaal Bhairava on a dark cloth; light a lamp of sesame (til) oil. Common offerings include black sesame, shami leaves, bilva, dark hibiscus, black urad as naivedya, camphor and incense. Begin with a short Ganapati invocation, then take sankalpa with name and gotra.
Dhyana is done on the dark form of the Lord seated on the black dog. The mula mantra and the Bhairava Gayatri are the core of the japa; many households also recite the Kaal Bhairava Ashtakam of Adi Shankaracharya at dusk or near midnight.
A minimum of 108 recitations is the usual home count; longer japa is undertaken by those who have taken a fuller sankalpa. After aarti with the sesame-oil lamp, tradition asks the devotee to feed a dog — especially a black or dark-coloured one — with rice, roti or milk, as direct seva to the Lord’s vahana. Some lineages also leave a lemon at a four-way junction after mentally offering obstacles into it; this is a regional Bhairava samskara, not a substitute for the puja itself.
Where a fire offering is preferred, the Kala Bhairava Homam is the rite the ashram priests perform on this Ashtami — with black sesame, ghee and the prescribed Bhairava mantras offered into the homa kunda — and telecast live to the devotee. Related protective and obstruction-removal rites are grouped under the protection homam catalogue.
Niyamas: What Tradition Asks You Not to Do
The Bhairava observances are precise about conduct on the day of the vrat. Meat, fish, onion, garlic and alcohol are set aside. Arguments, falsehood and cruelty to animals are avoided; mistreating a dog is treated as an affront to the Lord whose vahana it is. The mind is kept as steady as possible, and the night puja is not skipped — Kaal Bhairava worship is inherently a night observance.
Elders, guests and teachers are to be treated with respect. The vrat is kept with sincerity of sankalpa rather than with display. These niyamas apply equally to the ordinary monthly Kalashtami and to the Adhika observance; the Adhika day simply carries the same rules inside the extra month.
AstroBhava’s priests perform Kaal Bhairava rites from the house’s Yagna Ashram in Pollachi, Coimbatore District, with live telecast to devotees abroad. Yantra Pujas are performed in our consecrated sanctum. One clear sankalpa on 8 June 2026 is enough to begin; the date will not return with the same Adhika framing for years.
