“Diwali or Divali (also known as Deepavali, Tihar and the “festival of lights“) is an ancient Hindu festival celebrated in autumn every year.^[5][6] The festival spiritually signifies the victory of light over darkness.^[7][8][9] The festival 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.” *wikipedia
