Was Durga puja celebrated twice in a year?

Durga Puja is primarily celebrated once a year, during the Hindu month of Ashwin, which usually falls in September or October. However, some regions or communities might observe a second, smaller celebration known as "Nabami" or "Chhath," but these are not the main festival events. The major celebration is dedicated to the goddess Durga's victory over the buffalo demon Mahishasura, symbolizing the triumph of good over evil.
