Diwali / Deepavali
Diwali, or Deepavali, is celebrated by Hindus, Jains and Sikhs across the globe as the "Festival of Light," where the lights or lamps signify victory of good over the evil within every human being .
In North India, it is the homecoming of King Rama of Ayodhya after a 14-year exile in the forest. The people of Ayodhya (the capital of his kingdom) welcomed Rama by lighting rows (avali) of lamps (deepa), thus its name, Deepawali, or simply shortened as Diwali.
Diwali comes in the month of October or November.
