Datta Jayanti Navratri is associated with Hindu God Dattatreya. It begins nine days before the Dattatreya Jayanti day. In 2010, Datta Jayanti Navratri begins on December 12 and ends on December 20, 2010 – the Dattatreya Jayanti day. It is observed from the saptami or seventh day of the Shukla Paksha of Margashrish month to the full moon day in the month.
Dattatreya is the Trimurti Avatar – the united and single incarnation of Brahma, Vishnu and Shiva.
During the nine days special rituals are held in temples dedicated to Dattatreya.
Dattatreya remained an Avadutha throughout his life – a sage who remains in pure nature. He was a supreme yogi.
Dattatreya narrated the secrets of Vedanta to Lord Subrahmanya and this teaching later came to be known as Avadhuta Gita.
