Dussehra is a Hindu holiday that celebrates the victory of the avatar of Vishnu, Rama, over the demon king Ravana, who had abducted Rama’s wife, Sita. The festival’s name comes from the Sanskrit words “Dasha” meaning ten and “Hara” meaning defeat, signifying the defeat of Ravana’s ten heads. It is observed on the 10th day of the Hindu month of Ashvina, which falls in September or October and coincides with the full moon.
