Diwali or Deepavali is the Hindu festival of lights celebrated every year usually in the months of October or November.
It is one of the major festivals of Hinduism and it spiritually
signifies the victory of light over darkness, good over evil, knowledge over
ignorance, and hope over despair. The celebrations include millions of lights
shining on housetops, outside doors and windows, around temples and other
buildings in the communities and countries where it is observed. 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 Bikram
Sambat calendar. In the Gregorian calendar, Diwali night falls
between mid-October and mid-November.
