Dussehra, also called Vijayadashami, in Hinduism, holiday marking the triumph of Rama, an avatar of Vishnu, over the 10-headed demon king Ravana, who abducted Rama’s wife, Sita. The festival’s name is derived from the Sanskrit words dasha (“ten”) and hara (“defeat”). Symbolizing the victory of good over evil, Dussehra is celebrated on the 10th day of the month of Ashvina (September–October), the seventh month of the Hindu calendar, with the appearance of the full moon, an event called the “bright fortnight” (shukla paksha). Dussehra coincides with the culmination of the nine-day Navratri festival.
