Diwali is a five day festival that honors the victory of good over evil and brightness over darkness. It celebrates Lord Ram and his wife Sita returning to their kingdom of Ayodhya, following Ram and monkey god Hanuman's defeat the demon King Ravana and rescue of Sita from his evil clutches. It's known as the "Festival of Lights" for all the fireworks, small clay lamps, and candles that are lit. The candlelight makes Diwali a very warm and atmospheric festival, and it's observed with much joy and happiness.
