Raksha Bandhan 2026: The Computed Date, Tithi and Muhurat

Grahan on Raksha Bandhan 2026 — does it affect the rakhi?

No — the 28 August 2026 chandra grahan does not affect Raksha Bandhan in India. The partial lunar eclipse runs 06:54–12:32 IST that morning, but it is not visible from India, and by the classical rule sutak applies only where an eclipse is visible — so no sutak, no restriction. Tie the rakhi as normal (the purnima prevails until 09:48 IST; bhadra ended the previous evening, so the day is clear). Full details: 28 August 2026 grahan — time in India, visibility & sutak.

Raksha Bandhan 2026 falls on Friday, 28 August 2026. The governing tithi — the full moon of Shravana, when the rakhi is tied as a bond of protection — runs from 27-08-2026 09:09 IST to 28-08-2026 09:49 IST, computed from the ephemeris with the Lahiri ayanamsa, the way a Panchang actually derives it. The observance follows aparahna (afternoon).

A rare note for 2026: this same Purnima carries a partial lunar eclipse that is not visible from India — so by the classical visibility rule no sutak applies and Rakhi observances proceed entirely unaffected. The computed detail is in our August 2026 eclipse guide.

How the day is kept

Sisters tie the rakhi during the day's auspicious span — the aparahna (afternoon) window is preferred by tradition, and the Bhadra period, wherever it touches the day, is set aside first.

Why the tithi window matters more than the date

A Hindu festival is not a civil date; it is a tithi caught at a particular quality of time — aparahna (afternoon) here. When the tithi straddles two days, the rule decides the day, which is why two neighbouring calendars sometimes disagree while both cite the same sky. The window printed above is the actual astronomy; the rule applied to it is the tradition. Together they give you the answer the forwards never explain. For the method itself, see our muhurat & festivals guide.
