Diwali (also called Deepavali, दिवाली or दीपावली or தீபாவளி in Tamil) is a major Hindu, Jain, Sikh and Indian Buddhist festival/celebration. Known as the "Festival of Lights," it symbolises the victory of good over evil, and lamps are lit as a sign of celebration and hope for mankind. The reason for celebrating Diwali or Deepawali (lines of earthen lamps) is the return of Lord Ram, after killing Ravan (Demon) during his exile for 14 years. The day of killing Ravan is celebrated as Dussehra (19~21 days before Diwali). Celebrations focus on lights and lamps, particularly traditional diyas (as illustrated). Fireworks are associated with the festival in some regions of India.
Deepavali is celebrated for five consecutive days in the Hindu month of Ashwayuja. It usually occurs in October/November, and is one of the most popular and eagerly awaited festivals of India. Hindus, Jains and Sikhs alike regard it as a celebration of life and use the occasion to strengthen family and social relationships. For Jains it is one of the most important festivals, and beginning of the Jain year. It is also a significant festival for the Sikh faith.
