Diwali (or Deepavali, the festival of lights ) is an ancient Hindu festival celebrated in autumn (northern hemisphere) or spring (southern hemisphere) every year. One of the most important festival in Hinduism, it is an official holiday in many countries of the world: Fiji, Guyana, India, Pakistan, Malaysia, Mauritius, Nepal, Singapore, Sri Lanka, Suriname and Trinidad and Tobago. The festival spiritually signifies the victory of light over darkness or good over evil, knowledge over ignorance, and hope over despair. Its celebration includes 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 the Gregorian calendar, Diwali night falls between mid-October and mid-November.
Diwali is one of the most celebrated festivals for Indian Hindus in the United States. More than four million people of Indian origin observe the holiday with firework displays, indian sweets, savories and special herbs. And, of course, a lot of various lamps, candles and sparklers are lit on this holiday.
Diwali is not a nationwide public holiday in the United States, but some school districts hold no classes on the first day of the holiday.
