Kali Pujo is a tantric pujo performed on the new moon night of Kartik amabasya in October / November (Bengali month of Ashwin). This happens on the same day as Diwali celebrated in the rest of India. According to legend Raja Krishna Chandra who was the king of Navadipa, began this Bengali pujo of Mahakali in the eighteenth century. Since then, the tradition was continued by his descendants and by the rich zamindar families in Bengal under their patronage.
