Navratri also spelled Navaratri or Navarathri, is a multi-day Hindu festival celebrated in the autumn every year. It is observed for different reasons and celebrated differently in various parts of the Indian subcontinent.Theoretically, there are four seasonal Navratri. However, in practice, it is the post-monsoon autumn festival called Sharad Navratrithat is the most observed in the honor of the divine feminine Devi (Durga). The festival is celebrated in the bright half of the Hindu calendar month Ashvin, which typically falls in the Gregorian months of September and October.
In the eastern and northeastern states of India, the Durga Puja is synonymous with Navratri, wherein goddess Durga battles and emerges victorious over the buffalo demon to help restore Dharma. In the northern and western states, the festival is synonymous with "Rama Lila" and Dussehra that celebrates the battle and victory of god Rama over the demon king Ravana.
Celebrations include stage decorations, recital of the legend, enacting of the story, and chanting of the scriptures of Hinduism. The nine days are also a major crop season cultural event, such as competitive design and staging of pandals, a family visit to these pandals and the public celebration of classical and folk dances of Hindu culture.
