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.

More than 10,000 people are expected to visit the sacred temple, BAPS Shri Swaminarayan Mandir, where hundreds of vegetarian dishes will be offered, in celebration of Diwali.
