Guru Purnima 2026: The Computed Date, Tithi and Muhurat

By Dr. R.P. Sharma, Vedic astrologer since 1979 · timings computed on real sidereal positions

Guru Purnima 2026 falls on Tuesday, 28 July 2026. The governing tithi — the full moon of Ashadha, kept as the day of the Guru since the age of Veda Vyasa — runs from 28-07-2026 18:20 IST to 29-07-2026 20:06 IST, computed from the ephemeris with the Lahiri ayanamsa, the way a Panchang actually derives it. The observance follows the sunrise-prevailing (udaya) tithi.

How the day is kept

Disciples honour their teachers — spiritual and worldly — with gratitude, a simple puja, and often the year's first resolve of study. It is counted among the most sattvik days for beginning any learning.

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 — the sunrise-prevailing (udaya) tithi 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.
