Navratri, held annually in honour of Hindu Goddess Durga, is celebrated over a period of nine days where thousands of youth dance the night away in traditional costumes. Navratri starts on September 25 and will be celebrated until October 3.
In many parts of the country it is marked by celebrations involving prayer, fasting, music and dance among men and women.
It is famous for being high-spirited and Christians and Muslims are known to take part. They also take part in the Holi Hindu spring festival.
Meanwhile, the five-day Durga Puja festival will be celebrated from September 30 to October 3, and is the biggest religious event for Bengali Hindus.
Durga is attributed as the destroyer of evil and Hindus believe that the goddess symbolises power and the triumph of good over evil.
