Hanuman Deeksha viramana (Conclusion of 41-day Hanuman Diksha) is performed on Hanuman Jayanti in Vaishakha Masam as per Telugu calendar. Kondagattu, Kasapuram and Sri Maddi Anjaneya Swamy in West Godavari are the famous Hanuman temples where Hanuman Deeksha is taken and concluded. In 2012, date of Deeksha Viramana is May 15, Tuesday. As it falls on Tuesday (favorite day for Hanuman) it is considered even more auspicious.
Generally, Hanuman Deeksha is observed for 41 days (begins on Chaitra Purnima and ends on Vaishakha Bahula Dasami).
