Diwali will be observed on Oct. 18 2017. Diwali is celebrated on the 15th day of the month of Kartika in the Hindu calendar each year.
Diwali is an autumn festival which is widely celebrated in India and celebrated among some communities in the United States. While the date of Diwali does not change on the Hindu calendar, the shifting dates on the western calendar are due to the Hindu calendar being tied to the phases of the moon. Diwali is a five-day festival, with the main celebrations occurring on the third day.
Diwali, also called the Festival of Lights, celebrates Rama-chandra, the seventh incarnation of the god Vishnu. Lakshmi, the goddess of happiness and good fortune, is also celebrated during Diwali. Light, including fireworks, bonfires, and lamps are important symbols of Diwali, as the festival celebrates the triumph of light and righteousness over the forces of spiritual darkness.
