In West Bengal the day of Vijayadashami is not always same as that of other Indian states. When it happens, it is one day after of Vijayadashami in other states.
Most Indian states observe Vijayadashami based on Muhurata and prefer the day when there is suitable combination of Tithi and Nakshatra during afternoon. Many religious books including Purana suggest to observe Vijayadashami after considering appropriate Muhurata.
It seems with time West Bengal has drifted away from the above rule and prefers Dasami Tithi only without considering Muhurata to observe Vijayadashami.
Vijayadashami is celebrated as victory of Lord Rama over Demon Ravana and also triumph of Goddess Durga over the buffalo Demon Mahishasura. Vijayadashami is also known as Dussehra or Dasara. Nepal Vijayadashami is celebrated as Dashain.
