Goddess Durga was traditionally worshipped in the spring. The rituals of Basanti Puja are similar to those of Shardiya Durga Puja. Festival of nine nights dedicated to Goddess Durga, is observed in the spring during the month of Chaitra (March-April), from which it takes its name.
The festival is dedicated to Goddess Shakti and three of his most popular forms-goddesses, Durga , Lakshmi and Saraswati, while in some regions, the festival is dedicated to the worship of Shri Ram, and therefore it is customary to attend the reading of the Ramayana and the theatrical performances of the epic.
Popular belief has it that the goddess Durga was worshiped during the month Chaitra , known as Basanti Puja. But having Rama invoked the goddess Durga in the month of Ashwin (September-October) to get his blessing in the war against the demon Ravana, the celebrations of Durga Puja and Navratri has been postponed from Chaitra month Ashwin.
