"Diwali, the Hindu festival of lights, is the most popular of all the festivals from South Asia.
It is also the occasion for celebrations by Jains and Sikhs as well as Hindus.
The word Diwali comes from the Sanskrit word deepavali, meaning "rows of lighted lamps". Houses, shops and public places are decorated with small oil lamps called diyas.
People also enjoy fireworks and sweets too, so it's really popular with children."
