Dussehra is the last day of Navratri; it falls on the 10th day of the waxing moon during the Hindu month of Ashvin
Dussehra is also known as Vijaya Dasami, because of the victory of Ram over Ravana.
In the months of Ashwin and kartik, Hindus observe a 10 day ceremony of fast, rituals, celebrations, fiestas to honor the mother Goddess and triumph of Lord Rama over Demon Ravana. Dussehra also symbolizes the triumph of warrior Goddess Durga over the buffalo demon, Mahishasura. Thus, it is a celebration of victory of good over evil.
This celebration starts from Navratri and ends with the tenth day festival of “Dussehra”. Navratri and Dussehra is celebrated throughout the country at the same time, with varying rituals, but with great enthusiasm and energy as it marks the end of scorching summer and the start of winter season.
It lasts for ten days . At some places , the Ram Lila is staged and at once places , the Ramayana is recited. On the 10th day or the last day , a big fair is held .
Many Hindus also believe that it is lucky to start a new venture, project or journey on Dussehra. They may also exchange gifts of leaves from the Shami tree (Prosopis spicigera) as a symbol of the story of the Pandavas brothers' exile in the Mahabharata stories.
