This year the main date was on October 19. Diwali is observed by Hindus, Sikhs and Jains around the world and is often celebrated by street parties and fireworks.
The word itself means ‘series of lights’ and during the festival houses and shops are decorated with candles and lights.
Many people celebrate the legend of Hindu God Rama and his wife Sita’s returning to their kingdom in northern India after being exiled following the defeat of demon king Ravanna.
During the festival, families and friends share sweets and gifts and there is also a strong belief in giving to those in need.
It is also traditional for homes to be cleaned and new clothes to be worn.
The five-day festival, which coincides with Hindu New Year, is seen to be one of the most significant in the Indian culture.
