Date and Panchanga Basis
- Date: Sunday, July 18, 2027 (also observed as Vyasa Purnima)
- Rule: Ashadha Purnima, the full moon dedicated to the guru and to Vyasa.
- Reckoning: amanta lunar months; date fixed by the tithi prevailing at sunrise (udaya tithi).
This date is computed from sidereal Sun and Moon positions (Swiss-precision Meeus ephemeris, Lahiri ayanamsa), not copied from a stored calendar. Regional almanacs that apply a different local rule can occasionally differ by one day; where a festival anchors to a specific hour, such as midnight for Janmashtami or midday for Ganesh Chaturthi, the matching classical rule is used.
Significance
Guru Purnima honors the teacher lineage, anchored to sage Vyasa, compiler of the Vedas. In Jyotish tradition it is the year's principal day for honoring one's own teachers, falling as the monsoon Chaturmasya begins.
Timing Your Observance
A festival date names the day; a muhurta names the hour. For puja timing on July 18, consult the day's panchanga: the prevailing tithi and nakshatra, the choghadiya windows, and the Rahu Kaal period to avoid. The daily panchang, choghadiya timings, and Rahu Kaal calculator cover this for your city, and the birth chart calculator shows how the day's sky sits against your own chart.
