Dattatreya’s birth, on the evening of Margashirsha Purnima.
Dattatreya Jayanti is Margashirsha Shukla Purnima, the Purnima of the shukla paksha of Margashirsha, so its date is the day on which this tithi is running in pradosh kaal, the evening after sunset. A tithi begins and ends at a real minute, not at midnight, which is why the moment decides the day, and why the same festival can fall on a different date in another country.
For New Delhi, in IST.
Dattatreya Jayanti, or Datta Jayanti, is kept on Margashirsha Purnima as the birth of Lord Dattatreya, son of the sage Atri and his wife Anasuya. The Markandeya Purana and the Bhagavata Purana both tell of him, and he is worshipped as Brahma, Vishnu and Shiva in one. His birth is celebrated at pradosh, in the evening, when the Purnima holds, with a cradle and bhajans in Datta temples.
Dattatreya is honoured above all as the Guru: the Datta tradition of Maharashtra, Karnataka, Gujarat, Andhra Pradesh and Telangana sees him as the teacher of teachers. He is shown with three heads and six arms, under an audumbar (cluster fig) tree, with a cow behind him and four dogs at his feet, which tradition reads as the earth and the four Vedas. Many devotees complete a reading of the Guru Charitra by this day.
Bathe and clean the puja place, and set an image of Dattatreya, with padukas (sacred sandals) if you keep them, on a clean cloth.
Offer gandh (sandal paste), haldi-kumkum, akshat and flowers, and light a ghee diya and incense.
Read from the Guru Charitra, or chant “Digambara Digambara Shripad Vallabh Digambara” or “Shri Gurudev Datta”.
In the evening, while the Purnima holds, mark his birth as temples do: rock a small cradle with his image, shower flowers and sing a cradle song.
Do the aarti and share the prasad; in many Maharashtrian homes this is sunthavada, dry ginger powder with sugar, given after a birth celebration.
If you can, feed a cow or a dog, both shown with Dattatreya in his image.
Source: Markandeya Purana and Bhagavata Purana tell of his birth to Atri and Anasuya; the story of the three gods coming as guests is popular tradition
The Bhagavata Purana tells that the sage Atri performed long tapas, praying for a son like the Lord of the universe. Brahma, Vishnu and Shiva appeared before him together, and as their blessing sons were born to Atri and Anasuya from a portion of each: Soma from Brahma, Datta from Vishnu and Durvasa from Shiva.
Popular tradition tells it another way. Anasuya was so renowned for her devotion to her husband that Brahma, Vishnu and Shiva came to her hermitage as mendicants to test her, asking for alms on a condition that seemed impossible to meet. By the power of her devotion she turned the three into infants, fed them and rocked them in a cradle.
When Saraswati, Lakshmi and Parvati came looking for their husbands, Anasuya gave the three back in their own forms. Pleased, the gods offered her a boon, and she asked that they be born as her son. So Dattatreya was born, the three in one.
The Bhagavata Purana, in Book 11, also tells of an avadhuta who explained to King Yadu that he had learned from twenty-four gurus, among them the earth, the honeybee and the spider. Tradition identifies this avadhuta as Dattatreya.
What to do
What to avoid
A Purnima has the same month name in the Purnimanta and Amanta calendars, so this is Margashirsha Purnima everywhere. It is Datta Jayanti in Maharashtra and Karnataka and Dattatreya Jayanti elsewhere, kept with large gatherings at Ganagapur in Karnataka, Narsobawadi and Audumbar in Maharashtra, Girnar in Gujarat and Pithapuram in Andhra Pradesh.
Because the birth is kept at pradosh, the Jayanti goes to the day on whose evening the Purnima holds. When the Purnima begins in the afternoon, Datta Jayanti can fall a day before the Purnima snan-daan, which follows sunrise. Evening also comes at different times in different places, so cities can differ by a day.

Dattatreya Jayanti is kept on the day its tithi, Purnima, is running in pradosh kaal, the evening after sunset. The tithi begins and ends at the same instant all over the world, but sunset comes at its own hour in every place, so in the US or UK the day that holds it can be a day earlier than in India.
