Vijayadashami (IAST: Vijayadaśamī, pronounced [ʋɪʝəjəðəʃmɪ]]) also known as Dasahara, Dusshera, Dasara, Dussehra or Dashain is a major Hindu festival celebrated at the end of Navratri every year. It is observed on the tenth day in the Hindu calendar month of Ashvin, the seventh month of the Hindu Luni-Solar Calendar, which typically falls in the Gregorian months of September and October.
Vijayadashami is observed for different reasons and celebrated differently in various parts of South Asia. In the southern, eastern and northeastern states of India, Vijayadashami marks the end of Durga Puja, remembering goddess Durga’s victory over the buffalo demon Mahishasura to restore and protect dharma. In the northern and western states, the festival is synonymously called Dussehra (also spelled Dasara, Dashahara). In these regions, it marks the end of “Ramlila” and remembers God Rama’s victory over the Ravan. On the very same occasion; Arjuna alone decimated 1 lakh+ soldiers & defeated all Kuru warriors including Bhishma, Drona, Ashwatthama, Karna, Kripa etc.- there by significantly quoting the natural example of victory of good (Dharma) over evil (Adharma). Alternatively it marks a reverence for one of the aspects of goddess Devi such as Durga or Saraswati.
Vijayadashami celebrations include processions to a river or ocean front that carry clay statues of Durga, Lakshmi, Saraswati, Ganesha and Kartikeya, accompanied by music and chants, after which the images are immersed into the water for dissolution and a goodbye. Elsewhere, on Dasara, the towering effigies of Ravan symbolizing the evil are burnt with fireworks marking evil’s destruction. The festival also starts the preparation for one of the most important and widely celebrated Diwali, the festival of lights, which is celebrated twenty days after the Vijayadashami.
