On Chaitra Shukla Purnima, i.e., the full moon day of March-April the birth anniversary of Hanuman, the son of the Wind-god Maruti and Anjana Devi, is celebrated. People visit the shrines dedicated to Lord Hanuman, observe strict fast, offer prayers and puja, read the Ramayana and the Hanuman Chalisa.
On this occasion the idol of Hanuman is given a new coat of vermillion colour mixed with clarified butter and then richly decorated. Fairs are also held at some places near the shrines and charity feasts are also organized. Hanuman is considered to be one of the greatest embodiments of strength, speed, agility, learning and selfless service to Lord Rama.
