Diwali, the Hindu festival of lights, is the most popular of all the festivals from South Asia. It's also celebrated by Jains and Sikhs.
In Britain, as in India, the festival is a time to thoroughly spring-clean your home, wear new clothes and most importantly, decorate buildings with fancy lights.
The festival lasts for five days. Because of the lights, fireworks and sweets involved, it's a big favourite with children.
