The five-day party begins in October or November, and honors the Hindu goddess of wealth, Lakshmi. This year, it starts this Tuesday (November 10) or Wednesday (November 11), depending on where you are.

Diwali celebrates the triumph of light over darkness, or good over evil, which explains its other name, “the festival of lights.” Light features prominently in Diwali celebrations, in the form of candles and fireworks. People have time off from work and new clothes are purchased and worn.

Food also plays a central role in the holiday. On the fourth day of Diwali, which coincides with the Hindu New Year, people bring sweet foods and gifts to friends and family to signify good wishes for the coming year.
