In West Bengal the day of Maha Navami Puja varies from that of other states of India. It usually happens one day after the Mahanavami in other states.
In most of the Indian states, except Bengal, Mahanavami is observed based on Purva-Viddha rule. Purva-Viddha rule insists that if Navami Tithi prevails for 3 Muhurata before sunset on the previous day, then Mahanavami Puja and fasting should be observed on the previous day. If it happens, then both the Ashtami and Navami Puja including fasting are performed on the same day. However, it may be noted that this rule is applicable to Navami Puja and Navami fasting only, but not applicable to Navami Balidan. Various religious texts including Dharmasindhu and Nirnayasindhu have mentioned this rule.
In West Bengal, Para-Viddha rule is followed for observing Maha Navami. Para-Viddha rule insists that Mahanavami should be observed when it prevails at least for one Muhurata after Sunrise.
Further, in West Bengal, Mahanavami is the third and final day of Durga Puja and the Durga Puja on this day begins with Mahasnan and Shodashopachar Puja.
On Maha Navami, Goddess Durga is worshipped in the form of Mahisasuramardini, which means the Destroyer of the Buffalo Demon. It was on Maha Navami day Goddess Durga killed the demon Mahishasura.
