Durga Puja ( or or , listen: , “Worship of Durga”), also referred to as Durgotsava ( or , listen: , “Festival of Durga”) or Sharadotsav is an annual Hindu festival in South Asia that celebrates worship of the Hindu goddess Durga. It refers to all the six days observed as Mahalaya, Shashthi, Maha Saptami, Maha Ashtami, Maha Nabami and Vijayadashami. The dates of Durga Puja celebrations are set according to the traditional Hindu calendar and the fortnight corresponding to the festival is called Devi Paksha, “Fortnight of the Goddess”). Devi Paksha is preceded by Mahalaya, the last day of the previous fortnight Pitri Paksha, “Fortnight of the Forefathers”), and is ended on Kojagori Lokkhi Puja (“Worship of Goddess Lakshmi on Kojagori Full Moon Night”). Durga Puja festival marks the victory of Goddess Durga over the evil buffalo demon Mahishasura. Thus, Durga Puja festival epitomises the victory of Good over Evil. Durga Puja is widely celebrated in the Indian states of Assam, Bihar, Jharkhand, Manipur, Odisha, Tripura and West Bengal, where it is a five-day annual holiday. In West Bengal, Assam, Tripura, which has a majority of Bengali Hindus and Assamese Hindus, it is the biggest festival of the year. Not only is it the biggest Hindu festival celebrated throughout the state, it is also the most significant socio-cultural event in Bengali Hindu society. Apart from eastern India, Durga Puja is also celebrated in Delhi, Uttar Pradesh, Maharashtra, Gujarat, Punjab, Kashmir, Andhra Pradesh, Karnataka and Kerala. Durga Puja is also celebrated as a major festival in Nepal where 91% is Hindu, and in Bangladesh where the 8% population is Hindu. Nowadays, many diaspora Assamese and Bengali cultural organisations arrange for Durgotsab in countries such as the United States, Canada, United Kingdom, Australia, Germany, France, The Netherlands, Singapore and Kuwait, among others. In 2006, a grand Durga Puja ceremony was held in the Great Court of the British Museum. The prominence of Durga Puja increased gradually during the British Raj in Bengal and erstwhile Assam. After the Hindu reformists identified Durga with India, she became an icon for the Indian independence movement. In the first quarter of the 20th century, the tradition of Baroyari or Community Puja was popularised due to this. After independence, Durga Puja became one of the largest celebrated festivals in the whole world. It is also the largest open Air Art Exhibition in the World. Durga Puja also includes the worship of Shiva, who is Durga’s consort (Durga is an aspect of Goddess Parvati), in addition to Lakshmi, Saraswati with Ganesha and Kartikeya, who are considered to be Durga’s children. Worship of mother nature is done, through nine types of plant (called “Kala Bou”), including a plantain (banana) tree, which represent nine divine forms of Goddess Durga. Modern traditions have come to include the display of decorated pandals and artistically depicted sculptures (murti) of Durga, exchange of Vijaya greetings and publication of Puja Annuals.
