Deity Hanuman

1. Tithi

         A special feature of Hanuman Jayanti (note) is that according to some panchangs, the birthday of Hanuman falls on Ashvin Krushna paksha Chaturdashi (fourteenth day of the dark fortnight of the month of Ashvin), while according to others it is on Chaitra Pournima. In Maharashtra, Hanuman Jayanti (note) is celebrated on Chaitra Pournima.

2. Importance of celebrating Hanuman Jayanti

         On the day of Hanuman Jayanti, Deity Hanuman’s Principle is a thousand times more active when compared to other days. On this day, chanting ‘II Shri Hanumate Namaha II’ and worshipping Deity Hanuman with bhav (spiritual emotion) helps in getting maximum benefit of His Principle.

3. Method of celebration

         On this day, in a Hanuman temple spiritual discourses are started at dawn. Deity Hanuman was born at sunrise. At that time the spiritual discourse is concluded and the birth celebrations begin. Then the Hanuman Idol is worshipped and prasad is distributed to everyone.
