Goddess Jagadhatri is being worshiped on Gosthastami. Jagadhatri Puja is also referred to as another Durga Puja as it starts on Asthami tithi and ends on Dashami tithi; just like the Durga Puja. The date of the Puja is decided by the lunisolar Hindu calendar.
Goddess Jagadhatri is worshiped all over West Bengal and in some places of Orissa. In West Bengal, the Jagadhatri Pujas organized at Chandannagar, Hooghly, Rishra, Tehatta, Krishnanagar, Nadia and Baripada – had a special socio-cultural importance. In Kolkata, Jagadhatri Puja is also one of the major autumnal Hindu festivals, after Durga Puja and Kali Puja. In Ramakrishna Mission, Jagadhatri Puja was initiated by Maa Sarada Devi (the devoted companion & wife of Shri Ramakrishna), who was, according to popular Bengali belief, an avatar of Devi. So the Jagadhatri Puja is celebrated in all the centres of the Ramakrishna Mission all over the world.
