The Annual Festival in the Hindu calendar month of Margasira - i.e., 4th December of 2025 is Datta Jayanthi.

Jayanthi of Sir Dattatreya Swamy, an incarnation of Brahma, Vishnu and Maheshwara. The Adi-Guru (First Teacher) of the Adinath Sampradaya of the Nathas. The first "Lord of Yoga" with mastery of Tantra (techniques).

Form of Lord Sri Dattatreya: He is typically dressed as a simple monk,  with three heads and six hands, one head each for Brahma, Vishnu and Shiva who represent the Trimurti, the three main gods in Hinduism, and one pair of hands holding the symbolic items associated with each of these gods: Japamala and Kamandalu of Brahma, Shakha and Sudarshana Chakra of Vishnu, Trishula and Damaru of Shiva. Surrounded by four dogs and a cow, which symbolise the four Vedas and mother earth who nourishes all living beings. Situated in a forest or wilderness suggestive of his renunciation of worldly goods and pursuit of a meditative yogic lifestyle.

The book 'Shri Guru Charitra' is the life of 'Shri Guru Dattatreya'. This volume is regarded as divine, capable of blessing one and all who read it with respect and is placed with images of Gods and adored in almost all devotees' houses. It is much respected and is very popular like Vedas, Ramayan, Mahabharat, Bhagawat and other puranas in sanskrit. It is both read as sapthaha parayan grandha (weekly parayan book) and nithya parayan grandha (daily parayan book). If this book is read in a week's time (daily proportion specified in book) seated in one particular place of the house every day, it is said that the house will attain unexplainable peaceful environment and if read 1 chapter every day, the individual will attain unexplainable happiness along with the fulfillment of one wish the book is ready for.
