Diwali, or Dipawali, is India's biggest and most important holiday of the year. The festival gets its name from the row (avali) of clay lamps (or deepa) that Indians light outside their homes to symbolize the inner light that protects us from spiritual darkness. This festival is as important to Hindus as the Christmas holiday is to Christians.
Diwali, celebrated in October or November each year, originated as a harvest festival that marked the last harvest of the year before winter. India was an agricultural society where people would seek the divine blessing of Lakshmi, the goddess of wealth, as they closed their accounting books and prayed for success at the outset of a new financial year. Today, this practice extends to businesses all over the Indian subcontinent, which mark the day after Diwali as the first day of the new financial year.
Indians celebrate with family gatherings, glittering clay lamps, festive fireworks, strings of electric lights, bonfires, flowers, sharing of sweets, and worship to Lakshmi. Some believe that Lakshmi wanders the Earth looking for homes where she will be welcomed. People open their doors and windows and light lamps to invite Lakshmi in.
Over the centuries, Diwali has become a national festival that is enjoyed by most Indians regardless of faith: Hindus, Jains, Buddhists, and Sikhs.
