Durga Puja is celebrated with joy all over India, especially West Bengal in worship of Goddess Durga. Singing, dancing, sweets & gaiety are an integral part of the Durga Pooja Festival. People send Durga Puja Gifts to dear ones and express good wishes.

The worship of Durga in the autumn ('Sharad') is the year's largest Hindu festival of Bengal, Orissa, Tripura, Assam, Bihar, Jharkhand and other parts of East India as well as in Bangladesh. Durga Puja is also celebrated in Nepal and Bhutan according to local traditions and variations. Puja means "worship," and Durga's Puja is celebrated from the sixth to tenth day of the waxing moon in the month of 'Ashwin', which is the sixth month in the Bengali calendar. Occasionally however, due to shifts in the lunar cycle relative to the solar months, it may also be held in the following month, Kartik. In the Gregorian calendar, these dates correspond to the months of September/October.

In the Krittibas Ramayana, Rama invokes the goddess Durga in her battle against Ravana. Although she was traditionally worshipped in the spring, due to contingencies of battle, Rama had to invoke her in the autumn akaal bodhan. Today it is this Rama's date for the puja that has gained ascendancy, although the spring puja, known as Basanti Puja, is also present in the Hindu almanac. Since the season of the puja is Shôrot autumn, it is also known as Sharodia.

The pujas are held over a ten-day period, which is traditionally viewed as the coming of the married daughter, Durga, to her father, Himalaya's home. It is the most important festival in Bengal, and Bengalis celebrate with new clothes and other gifts, which are worn on the evenings when the family goes out to see the 'pandals' (temporary structures set up to venerate the goddess). Although it is a Hindu festival, religion takes a backseat on these five days: Durga Puja in Bengal is a carnival, where people from all backgrounds, regardless of their religious beliefs, participate and enjoy themselves to the hilt.
