The festival of Dussehra, which marks the triumph of victory of good over the evil, is celebrated on the tenth day of the bright half (waxing moon) of the Hindu month of Aswiyuja. The date for the festival is not fixed. In 2012, it will fall on 24th October. The festivities of Dussehra also mark the commencement of the winter season after a long, scorching summer. The occasion commemorates the victory of Rama over Ravana as well as the triumph of Goddess Durga over demon Mahishasura. Fairs, known as Ramlila, are organized on many parts of the occasion. It is the culmination of the nine-day celebrations of Navratri, which precedes Dussehra.
