Timings are local (DST adjusted). Tithi = begin → end of the festival's tithi in that city.
The tithi prevailing at local sunrise (Udaya tithi).
'Gurur Brahma Gurur Vishnu Gurur Devo Maheshwarah, Guruh sakshat Parabrahma tasmai Shri Gurave namah' — the guru is the remover of the darkness of ignorance (gu = darkness, ru = remover); the fruit of guru worship on Ashadha Purnima is knowledge, learning and spiritual progress through the guru's grace; with the worship of Vyasa, the worship of Shukadeva, Shankaracharya and one's own guru lineage (the guru mandala).
Shiva the first guru (Adiyogi) — on this Purnima he gave the science of yoga to the Saptarishis (the yoga tradition); the day for taking initiation into the guru mantra, beginning a new study/sadhana, guru vandana for students and honouring teachers; children give teachers flowers and cards, guru vandana in schools.
The Purnima vrat (fruit all day, paran after seeing the Moon in the evening), the Satyanarayan katha; from this Purnima the Chaturmas of saints (until Kartika Purnima — discourses and satsang in one place); the Kokila vrat (Ashadha Purnima — the story of Sati; some regions); 'Guru Purnima/Rishi puja' in Bengal-Odisha; the 'Guru Purnima/Teachers' Day' holiday in Nepal.
Yes — Sunday, July 18, 2027.
Purvahna (morning) Puja time: 5:52 AM to 11:53 AM (EDT). Other cities are in the table above.
Each row is in that city's own local time with daylight saving applied (Eastern Time (EST/EDT) for Toronto).
Vyasa (the guru of all gurus), Shiva-Dattatreya (the first guru), one's ishta deity, parents (the first gurus), the teacher; or whoever's teaching changed one's life — even the author of a book; bow to the guru principle — the 'Gurur Brahma…' verse is enough.
As means allow — fruit-clothes-flowers-dakshina; but the real dakshina is walking the path the guru showed, the vow of one rule/renunciation, service in the guru's work; if there is no guru, donate books, a poor student's fees/notebooks and pens — the gift of learning is guru dakshina itself.
Yes — Guru Purnima is the best day for initiation (the guru mantra), a new study, beginning a sadhana, the first lesson in music/art, wearing rudraksha; ashrams hold group initiations; the Abhijit muhurat (above) is best.
The four months from Devshayani Ekadashi/Guru Purnima to Devuthani/Kartika Purnima — Vishnu's sleep, no weddings or other auspicious ceremonies; saints stay in one place and give discourses; householders keep one rule (sattvic food, Gita reading, celibacy, charity); in Jainism and Buddhism too (the rains retreat).
