Kamika Ekadashi falls on Ashadh Krishna Ekadashi (Maharashtra's amanta convention; North India calls it "Shravan Krishna") — a fasting vrat dedicated to Vishnu (as Sridhar). Since it's the next Ekadashi after Ashadhi/Devshayani, it's regarded as the first Ekadashi of Chaturmas. This year (2026): Sunday, 9 August.
The first Ekadashi of Chaturmas: Chaturmas (Vishnu's yogic sleep) begins with Ashadhi/Devshayani (Ashadh Shukla Ekadashi); Kamika is the next (Krishna-paksha) Ekadashi after it — so it's widely described as "the first Ekadashi of Chaturmas." Some panchang sources don't apply this seasonal label, so take it as a commonly used descriptive reference, not a fixed rule.
The tulsi mahatmya (its most distinctive feature): Kamika's mahatmya text places special emphasis on tulsi worship — worshipping Vishnu with tulsi leaves is held to be more pleasing to him than gems and pearls; worshipping Keshav with tulsi manjari (flower clusters) is believed to destroy a lifetime's sins. Tulsi is offered to Vishnu on every Ekadashi — but Kamika's mahatmya carries a particularly strong emphasis on it.
Atonement and the merit of Vajapeya yajna: by tradition, simply remembering Kamika Ekadashi grants the merit of a Vajapeya yajna and removes all sins; one who keeps a night vigil is said to be spared an unfortunate fate. The glory of donating lamps is also described — lighting a lamp before Vishnu is held to bring special merit (satisfying one's ancestors, attaining heaven). This should be read as Puranic praise, not a universal guarantee.
An important distinction should be kept in mind about Kamika's legend — the ancient Gita Press mahatmya text carries no person-centred story at all; it's purely a glorification (mahatmya). The "Kshatriya who killed a Brahmin" story found on modern sites doesn't appear in that ancient text.
A. The mahatmya (the legend's core): Krishna narrates this glory to Yudhishthira — as it was once told by Brahma in answer to Narada's question. This Ekadashi's name is "Kamika"; simply remembering it grants the merit of a Vajapeya yajna. On this day, Vishnu should be worshipped under the names Sridhar, Hari, Vishnu, Madhav, and Madhusudan — its merit is held to be rare even compared to bathing at Ganga, Kashi, Naimisharanya, or Pushkar. Worshipping Keshav with tulsi manjari is said to destroy a lifetime's sins; donating lamps day and night is said to satisfy one's ancestors and grant heaven.
B. The "Kshatriya-Brahmin-killing" story — a modern, widely circulated version: many modern sources tell this story — a valiant Kshatriya accidentally (in some versions, in anger) killed a Brahmin; burdened with the sin of killing a Brahmin, he was even denied the right to a proper cremation. On the advice of sages/Brahmins, he observed the Kamika Ekadashi vrat (worship of Sridhar, tulsi, and feeding Brahmins), and Vishnu appeared to him and freed him from that sin. This story doesn't appear in the ancient Gita Press mahatmya text — there, the mention of a "Kshatriya" occurs in a different (Apara Ekadashi) chapter, not in Kamika's. So this story is noted here as a "modern, widely circulated version," not as part of the ancient mahatmya.
Puranic attribution also varies — most modern sources credit this legend to the Padma Purana, while some credit the Brahma-Vaivarta Purana. Neither is treated as final here.
Devotees of Vishnu, especially those who fast on every Ekadashi, observe Kamika as the annual cycle's first Chaturmas Ekadashi. Those seeking atonement and peace observe this vrat especially for its sin-removing purpose, given both the legend (freedom from Brahmin-killing) and the tulsi mahatmya.
The sequence below is compiled from multiple sources as a general guide — not a fixed, single-correct ritual; it can vary by family and local custom.
An image or murti of Vishnu (as Sridhar), clean cloth, sandalwood paste-haldi-kumkum-akshata, tulsi leaves/manjari and garlands, incense and a lamp, panchamrit and sesame seeds (by tradition), fruit-based naivedya, the Vishnusahasranama or legend text, and food-cloth-water-lamp-dakshina for charity.
It's widely held that rice, wheat, barley, and all lentils are avoided on Ekadashi; a light sattvic meal is taken on Dashami, with parana on Dwadashi. Some devotees observe a waterless fast, while most take a fruit-based diet — fruit, milk, sabudana, potato; both are traditionally accepted. Chanting and satsang are part of the day, along with avoiding falsehood, anger, onion-garlic, alcohol, and daytime sleep. Parana should be done on Dwadashi, after Harivasar ends, at the proper time — the exact clock-time varies by location and year; this year the Dwadashi ends early in the morning, so pay particular attention to the parana time.
The common Vishnu chant: "Om Namo Bhagavate Vasudevaya" — meaning: "Salutations to Lord Vasudeva (Vishnu)." Hearing the Kamika legend carries special significance (by tradition, hearing it alone grants the merit of a Vajapeya yajna). The full text of the Vishnusahasranama isn't given here either. The exact aarti varies by tradition.
Kamika is a pan-India Vaishnav Ekadashi — it doesn't carry the distinctly Maharashtrian festival identity that Vat Purnima or Ashadhi Ekadashi do, and no distinct Maharashtra-specific custom has been independently documented. In Maharashtra (amanta), it's "Ashadh Krishna Ekadashi"; in North India (purnimanta), the same occasion is known as "Shravan Krishna Ekadashi" — the date and tithi are the same (9 August 2026), only the month's name differs. In Maharashtra, two Ekadashis fall within Ashadh itself — Shukla (Ashadhi/Devshayani) and Krishna (Kamika). Being the first Ekadashi of Chaturmas, which began with Ashadhi, matters to Warkari and Chaturmas-observing Marathi families.
| Date (2026) | Day | Tithi | Nakshatra | Note |
|---|---|---|---|---|
| 9 August | Sunday | Ashadh Krishna Ekadashi | Mriga | Kamika Ekadashi; parana on 10 August (Dwadashi, ends 08:00 AM — a narrow window) |
Future years: the tithi stays the same (Ashadh Krishna Ekadashi); the Gregorian date follows that year's panchang and is only known once that year's panchang is published.
