The Full Moon of the Teacher
Guru Purnima honours the principle of the guru — everyone and everything that has carried light into one's darkness. Its anchor is Veda Vyasa, born on this full moon: the sage who arranged the one Veda into four, composed the Mahabharata and the Brahma Sutras, and stands at the head of nearly every Hindu lineage of learning — which is why the day is equally Vyasa Purnima, and why every teacher's seat is called the vyasa-peetha. The yoga tradition adds its own origin: on this full moon Shiva as Adiyogi is said to have turned to face his first seven disciples, becoming Adi Guru, the first teacher. The famous shloka of the day places the guru beside Brahma, Vishnu and Shiva — because creation gives you a world, but only a teacher shows you what it means.
How Guru Purnima Is Observed
Those with a living guru or lineage perform guru puja — the teacher's feet honoured with flowers, the Guru Gita or guru stotras recited, and the day spent in satsang and study as the truest offering. Those without a formal guru are not left out: parents are the first gurus, and the tradition explicitly extends the day to them, to schoolteachers, and to anyone from whom one has genuinely learned — a visit, a call, a pranam, a gift. For monastics the full moon opens chaturmas, the four monsoon months of staying put and teaching. Many keep a fast or a sattvic day, and spend time with whatever text has been their teacher.

Guru Purnima in Ottawa & Canada
The Purnima is computed astronomically, so Ottawa's date — calculated on this page for Eastern time — can occasionally differ from India's. Guru Purnima may be the most portable festival in the calendar: it needs no murti, no market, no season — a July evening in Ottawa under the same full moon serves perfectly. Natural observances here: a call or letter to teachers back in India or across Canada before the time difference closes the day; the Guru Vandana from our library (linked below) with children, teaching them to honour their schoolteachers too; reading from a text in our Philosophy or Saints sections — Adi Shankaracharya and the great acharyas are the tradition's towering gurus. Ottawa's mandirs and yoga communities hold Guru Purnima satsangs — see our Hindu temples in Ottawa guide.

Questions
When is Guru Purnima this year in Ottawa?
The exact Ottawa date — computed astronomically for the Canadian timezone — is shown in the Festivals & Dates list on this page.
I don't have a guru — how do I observe Guru Purnima?
Honour whoever has taught you: parents are the first gurus, and schoolteachers, mentors and even books count within the tradition's spirit. A pranam, a call of gratitude, or a day of sincere study are all complete observances.
Why is it also called Vyasa Purnima?
It is kept as the birth anniversary of Veda Vyasa, who organized the Vedas, composed the Mahabharata and seeded nearly every lineage of Hindu learning. Honouring him honours the entire chain of teachers descending from him.
