Navaratri is a festival dedicated to the worship of the Hindu deity Durga. The word Navaratri means ‘nine nights’ in Sanskrit, navameaning nine and ratri meaning nights. During these nine nights and ten days, nine forms of Devi are worshipped. The tenth day is commonly referred to as Vijayadashami or “Dussehra”
Navaratri represents a celebration of the Goddess Amba, (the Power). Navratri commences on the first day (pratipada) of the bright fortnight of the lunar month of Ashwin. The festival is celebrated for nine nights once every year during the beginning of October, although as the dates of the festival are determined according to the lunar calendar, the festival may be held for a day more or a day less.
The NINE colors of Navratri collectively represent the spirit of a woman, who possesses the grace and valor of the Goddess Durga herself. Navaratri is celebrated five times a year. They are Vasanta Navaratri, Ashadha Navaratri, the Sharad Navaratri, the Paush/Magha Navaratri and the Magha Navaratri.
