Guru Purnima 2026 falls on Wednesday, 29 July, observed on the full moon of the lunar month of Ashadha. The Purnima tithi begins at 6:22 PM on 28 July and ends at 8:07 PM on 29 July. The day is also called Vyasa Purnima, marking the birth of Veda Vyasa, the compiler of the Vedas and author of the Mahabharata. Below is what the day actually marks, the Vyasa Puja vidhi practised in Smarta households and at Hindu monastic institutions, and the parallel Buddhist observance of the same date as Dharma Chakra Pravartana Diwasa.

- Ashadha Purnima tithi: 6:22 PM on 28 July to 8:07 PM on 29 July.
- Day for puja: 29 July (the day on which Purnima prevails at sunrise).
- Vyasa Puja sankalpa: traditionally during sunrise to noon.
- Chaturmasya begins: the four-month monsoon retreat for sannyasins starts on the same Purnima.
Why this Purnima and not another
Ashadha Purnima is the Purnima on which Veda Vyasa (Krishna Dvaipayana Vyasa) is traditionally said to have been born, and the day on which he completed the division of the Vedas into the four samhitas. The same day is also identified in the Skanda Purana as Vyasa Pujana Diwasa, when the line of teachers (guru-parampara) is honoured by reciting the names of the rishis going back to Vyasa.
The Mahabharata is structured as Vyasa’s narration to the divine scribe Ganesha. Within that text the parampara of teaching is itself preserved: Brahma to Vasishtha to Shakti to Parashara to Vyasa, and from Vyasa to his disciples Paila, Vaisampayana, Jaimini, Sumantu and Suka. The Ashadha Purnima puja reaches back through this line.
The Buddhist tradition identifies the same date as the day the Buddha delivered the first sermon (Dhammacakkappavattana Sutta) at Sarnath, two months after his enlightenment. The Theravada countries observe this as Asalha Puja Day. The simultaneity is one of the closer parallels between Hindu and Buddhist calendars.
The Vyasa Puja vidhi
The classical household form is a short morning puja before a chowki (low wooden seat) on which an image or picture of Veda Vyasa and the family’s living or departed guru is placed. The sequence:
- Snana and sankalpa: the householder bathes, dons clean cotton, and declares the sankalpa naming the date and the intent (Vyasa Pujana, guru-smarana).
- Padya, arghya, achamana: water for feet, water for hands, water for sipping, offered to the placed image.
- Vyasa Stuti recitation: the standard verses from the Mahabharata’s opening or the Brahma Sutra Bhashya invocation.
- Guru Stotra: the Gurustotram beginning “Guru Brahma Guru Vishnu” is the most widely used; the Adi Shankara Guru Ashtakam is the longer alternative.
- Dakshina and pranama: a small dakshina (offering) is placed before the chowki; in monastic practice it is given to the abbot of the sampradaya.
For initiated disciples, the Guru Purnima visit to one’s own guru, or to the matha to which the family is linked, is the principal observance. The Shankara mathas at Sringeri, Dwaraka, Puri and Jyotirmath, the Ramanuja mathas at Srirangam and Melukote, and the Madhva matha at Udupi all conduct elaborate Vyasa Puja on this morning.
Chaturmasya: the four-month vow
Ashadha Purnima is also the day Chaturmasya begins, the four-month period during which Hindu sannyasins of the dashanami and other ascetic orders remain at a single location and do not travel. The reason given in the Dharmashastras is practical: the monsoon makes travel difficult and walking risks treading on the abundant insect life of the rainy season, which violates ahimsa. The Vaishnava tradition reads it as Vishnu’s yoga-nidra, a four-month sleep that begins on Devshayani Ekadashi (which falls a few days before Ashadha Purnima) and ends on Devutthana Ekadashi in Kartika.
Householders observing Chaturmasya make smaller vows during these four months: avoiding particular foods (curd in Shravana, milk in Bhadrapada, ghee in Ashwina), avoiding travel where possible, and adding daily readings of the Bhagavata or other scripture. Chaturmasya ends on Kartika Shukla Ekadashi, this year 21 November 2026.
Common questions
Does Guru Purnima honour a personal guru or Vyasa?
Both. The day is canonically Vyasa Purnima, and the line of teachers from Vyasa onward is the universal reference. Within that frame, a disciple’s own living or departed teacher is honoured as the most recent member of the same parampara. The two readings are not separate; the personal guru sits at the visible end of the line that runs back to Vyasa.
What is dakshina, and how much should it be?
Dakshina is the offering placed before the guru after the puja. The classical guidance is yatha-shakti, according to one’s capacity, with the form mattering more than the amount. Cash, cloth, fruit, books and time-as-service all qualify. The Sringeri Shankara Matha and other major centres publish dakshina envelopes for those who prefer a defined amount.
Is Guru Purnima the right day to take diksha?
Many sampradayas treat it as among the most auspicious days for initiation (mantra-diksha or sannyasa-diksha). The Smarta and Shankara traditions in particular concentrate diksha ceremonies around Ashadha Purnima. Other lineages favour Maha Shivaratri or the birth dates of their tradition’s founders. The guru’s instruction is binding on the question.
One limitation worth noting
For what it’s worth, the most rewarding household observance is the simplest one: a clean morning puja, the Gurustotram, and a phone call or visit to a teacher who has shaped one’s understanding, religious or otherwise. The elaborate Vyasa Puja vidhi above is for those within an active sampradaya; outside such a context, simplicity is closer to the spirit of the day. The specific monastic schedules at the Shankara mathas and others change yearly and should be checked at the matha’s own publication.
