Diwali - Indian Festival of Lights.
Diwali is a five day festival that represents the start of the Hindu New Year. It honours the victory of good over evil, and brightness over darkness. It also marks the start of winter.
Each day the festival has a different meaning but the main festivities take place on the 3rd day of the festival - this year today - the 26.10.2011. On this day lots of small clay lamps called Diyas and candles are lit and placed in houses and fireworks are let off everywhere across the country, giving Diwali it's name - The Festival of Lights.
