This month marks one of Hinduism’s most celebrated festivals. Diwali, the annual festival of lights, begins on Oct. 20. Celebrations last five days, and include activities such as gift-giving, fireworks and even gambling.

Diwali, derived from the word “Deepavali,” meaning “a row of lights,” is typically celebrated by socializing and exchanging gifts. The dates of the festival are based on the Hindu lunar calendar, typically falling in late October or early November. Shoppers crowded markets to buy flowers, lanterns and candles.

The biggest public holiday in India, Diwali features prayers for prosperity and good fortune — and lots of sweets.
