(From Wikipedia) Diwali (or Deepavali, the “festival of lights”) is an ancient Hindu festival celebrated in autumn (northern hemisphere) or spring (southern hemisphere) every year. Diwali is one of the largest and brightest festivals in India. The festival spiritually signifies the victory of good over evil. The preparations and rituals typically extend over a five-day period, but the main festival night of Diwali coincides with the darkest, new moon night of the Hindu Lunisolar month Kartika. In the Gregorian calendar, Diwali falls between mid-October and mid-November.
