Raksha Bandhan 2026: 27 or 28 August? What the Panchang Actually Says
Purnima runs 27 Aug 09:08 to 28 Aug 09:48 IST; Bhadra takes its first half, 27 Aug 09:08–21:28. Hour by hour: why our panchang gives 28 August morning (sunrise to 09:48) as the rakhi window, why some list 27 August night, and a decision table for Delhi, Mumbai, Kolkata, Chennai.
Every year the same question comes first: is Raksha Bandhan 2026 on 27 August or 28 August? This year the confusion is real: the Purnima tithi is split almost in half across the two days, and Bhadra sits on the half that would otherwise decide it. This article does not repeat the muhurat list or the puja vidhi; it walks through the decision itself, hour by hour, so you can see which rule gives which date.
The short answer
Our panchang places rakhi on Friday 28 August 2026, from sunrise until 09:48 IST (Delhi 05:58–09:48). The alternative that several panchangs list is Thursday 27 August after 21:28 IST, once Bhadra has ended and while Purnima is still running. The daytime and evening of 27 August fall inside Bhadra; no tradition we know of recommends tying rakhi then.
The tithi window, minute by minute
Three timestamps decide everything. Delhi, IST:
| Event | Time |
|---|---|
| Shravana Shukla Chaturdashi ends, Purnima begins | Thursday 27 August, 09:08 |
| Bhadra (Vishti karana) — the first half of Purnima | 27 August, 09:08 to 21:28 |
| Aparahna on 27 August (Delhi sunrise 05:57, sunset 18:47) | 13:39 to 16:13 — inside Bhadra |
| Pradosh on 27 August (about three muhurtas after sunset) | roughly 18:47 to 21:11 — inside Bhadra |
| Sunrise on 28 August (Delhi) | 05:58 — Purnima at sunrise |
| Purnima ends, Krishna Pratipada begins | Friday 28 August, 09:48 |
| Rahu Kaal on 28 August (Delhi) | 10:46–12:22 — after Purnima, no effect on rakhi |
Purnima lasts about 24 hours 39 minutes in all; its first half, 12 hours 19 minutes, is Bhadra.
Why Bhadra ends at 21:28
Each tithi is divided into two karanas. In Shukla Paksha the first half of Purnima is Vishti karana — the "Bhadra" of the calendars; the second half is Bava. At sunrise on 27 August the karana is Vanija, the second half of Chaturdashi, and Vishti begins the moment Purnima does, at 09:08:42. Half of 24:39:18 is 12:19:39; add that to 09:08:42 and Bhadra lifts at 21:28:21 — 21:28 for practical purposes. At sunrise on 28 August the karana is already Bava — the whole of Bhadra belongs to the 27th. Some panchangs print 21:30–21:35; the gap is ephemeris and rounding, not a different rule.
One detail you will see quoted: at 09:08 the Moon is in Makara (Capricorn), and tradition calls a Bhadra that begins with the Moon in Makara "Patala-vasi", less harmful. But between the afternoon and evening of the 27th the Moon moves into Kumbha (Aquarius), whose Bhadra is "Mrityuloka-vasi", the kind avoided outright. We do not think that argument is strong enough to put rakhi in the daytime of the 27th. The texts do not explain what Bhadra does to a rakhi; they simply prohibit it — the well-known line says Shravani and Phalguni, the rakhi rite and Holika, are the two things never done in Bhadra.
27 August: the rule that picks it
The classical first preference for Raksha Bandhan is a Purnima that covers aparahna — the fourth of the five equal parts of the day — and is free of Bhadra. On 27 August aparahna in Delhi runs 13:39 to 16:13: Purnima, yes, but Bhadra too. The fallback is pradosh, the period after sunset, 18:47 to about 21:11 in Delhi; that is still inside Bhadra. The last fallback is the moment Bhadra ends, 21:28, with Purnima continuing through the night. Panchangs that rank "after Bhadra, same day" above "next morning" therefore give 27 August night. It is a legitimate reading, simply an inconvenient one — late at night, when families are rarely together.
Note also that at sunrise on 27 August the tithi is Chaturdashi, not Purnima; any tradition that insists on udaya tithi leaves the 27th out altogether.
28 August: why our panchang makes it primary
On 28 August Purnima is present at sunrise in every Indian city and lasts until 09:48 — 3 hours 50 minutes after Delhi sunrise. The reading of the nirnaya texts (Nirnayasindhu, Dharmasindhu) that panchang-makers generally follow is this: when both aparahna and pradosh of the first day are spoiled by Bhadra, and on the next day Purnima remains for at least three muhurtas (about 2 hours 24 minutes) after sunrise, the rite moves to the next morning. That condition is met comfortably this year everywhere in India; the latest sunrise in the country is before 06:30.
Three things line up: udaya Purnima, no Bhadra at all, and daylight. That is why our calendar marks Raksha Bandhan on 28 August with the window sunrise to 09:48. After 09:48 Krishna Pratipada begins and the tithi basis is gone; Rahu Kaal (10:46–12:22) starts after that anyway. The partial lunar eclipse of the same date is not visible from India and does not affect rakhi; that question is handled separately in Raksha Bandhan 2026 and the eclipse day.
Two traditions, one table
| Rule | Day it selects | Window |
|---|---|---|
| Udaya tithi, with Purnima lasting three muhurtas or more the next morning | 28 August, Friday | Sunrise to 09:48 |
| Aparahna or pradosh Purnima, same day once Bhadra ends | 27 August, Thursday — night | 21:28 onward through the night (Purnima runs to 09:48) |
| Treating "Patala-vasi" Bhadra as harmless and using the 27th by day | 27 August — daytime | Not recommended by us |
This is why two calendars print two dates and both are internally consistent: the disagreement is about the priority of rules, not the arithmetic.
Decision table by city
Purnima ends at the same instant, 09:48 IST, across India, and Bhadra ends at the same 21:28 on the 27th. Only sunrise differs, which changes how long the morning window is on the 28th.
| City | Sunrise 28 Aug (approx.) | Primary window, 28 Aug | Length | 27 Aug option |
|---|---|---|---|---|
| Delhi | 05:58 | 05:58–09:48 | 3 h 50 min | after 21:28, night |
| Mumbai | 06:23 | 06:23–09:48 | 3 h 25 min | after 21:28, night |
| Kolkata | 05:18 | 05:18–09:48 | 4 h 30 min | after 21:28, night |
| Chennai | 05:58 | 05:58–09:48 | 3 h 50 min | after 21:28, night |
Kolkata has the earliest sunrise and is still well inside Purnima. Mumbai has the latest, and the three-muhurta test is still passed there by 08:47. In all four cities pradosh on the 27th ends before Bhadra does, so the 27 August option is a night option everywhere. Sunrise varies by city; for borderline cases check your own local panchang.
What to do, practically
- If brother and sister are together: tie the rakhi on the morning of 28 August, after bathing, before 09:48. Between 07:00 and 09:30 is the comfortable stretch.
- If the morning of the 28th is impossible (travel, duty, different cities): 27 August after 21:28 at night is Bhadra-free Purnima.
- The afternoon and evening of the 27th are Bhadra. Avoid them, however convenient.
- After 09:48 on the 28th the tithi is Pratipada. If you are late anyway, it remains a bond of affection, not a fault; just do not call it a muhurat.

In short
Purnima runs from 27 August 09:08 to 28 August 09:48 IST. Bhadra runs from 27 August 09:08 to 21:28. Primary window: 28 August, sunrise to 09:48. Alternative: 27 August night, after 21:28. Not the daytime of the 27th.
Regional traditions differ on tithi decisions; treat your family priest or local panchang as final.
