what is diwali in hinduism

Diwali is one of the major religious festivals in Hinduism, Jainism, and Sikhism, lasting for five days from the 13th day of the dark half of the lunar month Ashvina to the second day of the light half of the lunar month Karttika. It is Indias biggest and most important holiday of the year, celebrated by more than a billion people. The festival is associated with Lakshmi, the Hindu goddess of wealth, prosperity, and good fortune. The meaning of Diwali differs depending on region and tradition. Among Hindus, the most widespread custom is the lighting of diyas (small earthenware lamps filled with oil) on the night of the new moon to invite the presence of Lakshmi. In Bengal, the goddess Kali is worshipped. During the festival, diyas are lit and placed in rows along the parapets of temples and houses and set adrift on rivers and streams. Homes are decorated, and floors inside and out are covered with rangoli, consisting of elaborate designs made of colored rice, sand, or flower petals. The doors and windows of houses are kept open in the hope that Lakshmi will find her way inside and bless the residents with wealth and success. The festival is also celebrated with worship, sharing sweets, fireworks, and lights. The names and events of the individual days of Diwali differ depending on the region and tradition, but they all ultimately represent the victory of good over evil.
