Dussehra, also known as Vijayadashami, is a Hindu festival that commemorates the triumph of good over evil. Dusshera is celebrated on the tenth day of Ashvin, the seventh month of the Hindu Luni-Solar Calendar, which occurs between September and October in the Gregorian calendar.
In different parts of the India, Vijayadashami or Dusshera is commemorated and celebrated for different reasons. Vijayadashami is the end of Durga Puja in India's southern, eastern, northeastern, and some northern states. The event is known as Dussehra in the northern, central, and western states, and it commemorates lord Rama's victory over Ravan at the end of Ramlila.
In the famous Hindu epic Ramayana, Ravana kidnaps Rama's wife Sita in the Ramayana to take revenge on Rama and Lakshmana for cutting off Surpanakha's nose. In the end, Rama triumphs over Ravana and saves Sita. The triumph is then commemorated by the burning of the effigies of Ravana. The tenth day, Dussehra, is the end of Navratri's nine-day celebrations.
According to another legend, Goddess Durga battled and killed Mahishasura on this day. The day is known as Vijayadashmi. The nine days leading up to Vijayadashami are dedicated to a different powerful manifestation of Goddess Durga.
