Durga Puja

Origin of the autumnal ceremony 'Sharadiya'

In Bengal, Durga Puja is also called Akalbodhan, Sharadiya Pujo, Sharodotsab, Maha Pujo, Maayer Pujo. 

The actual worship of the Goddess Durga as stipulated by the Hindu scriptures falls in the month of Chaitra, which roughly overlaps with March or April. This ceremony is however not observed by many and is restricted to a handful in the state of West Bengal.
 The more popular form, which is also known as Sharadiya (Autumnal) Durga Puja, is celebrated later in the year with the dates falling either in September or October. Since the Goddess is invoked at the wrong time, it is called "Akaal Bodhon" in Bengali.
 While the most recent revival of the Autumnal worship of Goddess Durga can be traced to revivalist tendencies in the early freedom movement in Bengal, the first such Puja was organised by Raja Nabakrishna Deb of the Shobhabazar Rajbari of Calcutta in honour of Lord Clive in the year 1757. The puja was organised because Clive wished to pay thanks for his victory in the Battle of Plassey. He was unable to do so in a Church because the only church in Calcutta at that time was destroyed by Siraj-ud-Daulah. Indeed many wealthy mercantile and Zamindar families in Bengal made British Officers of the East India Company guests of honour in the Pujas. The hosts vied with one another in arranging the most sumptuous fares, decorations and entertainment for their guests. This was deemed necessary since the Company was in charge of a large part of India including Bengal after the battles of Plassey and Buxar.
