What is Diwali, the Festival of Lights? How is it celebrated in India and the diaspora?

Diwali is the most important festival of the year in India — and for Hindus in particular.

It is celebrated across faiths by more than a billion people in the world’s most populous nation and the diaspora. Over five days, people take part in festive gatherings, fireworks displays, feasts and prayer.

Diwali is derived from the word “Deepavali,” which means “a row of lights.” Celebrants light rows of traditional clay oil lamps outside their homes to symbolize the victory of light over darkness and knowledge over ignorance.

The dates of the festival are based on the Hindu lunar calendar, typically falling in late October or early November.

This year, the holiday is being celebrated on Oct. 31 and Nov. 1. In the U.S., Diwali falls on Halloween this year, which has triggered quite a few #Diwaloween memes on social media where some celebrants can be seen lighting diyas in their scary costumes or handing out laddoos to trick-or-treaters.

While Diwali is a major religious festival for Hindus, it is also observed by Sikhs, Jains and Buddhists. The origin story of Diwali varies depending on the region. All these stories have one underlying theme — the victory of good over evil.

In southern India, Diwali celebrates the victory of Lord Krishna’s destruction of the demon Naraka who is said to have imprisoned women and tormented his subjects. In northern India, Diwali honors the triumphant return of Lord Rama, his wife Sita, and brother Lakshmana, from a 14-year exile in the forest.

The festival brings with it a number of unique traditions, which also vary by the region. What all celebrations have in common are the lights, fireworks, feasting, new clothes and praying.

—In southern India, many have an early morning warm oil bath to symbolize bathing in the holy River Ganges as a form of physical and spiritual purification.

—In the north, worshipping the Goddess Lakshmi, who symbolizes wealth and prosperity, is the norm.

Gambling is a popular tradition because of the belief whoever gambled on Diwali night would prosper throughout the year. Many people buy gold on the first day of Diwali, known as Dhanteras — an act they believe will bring them good luck.

Setting off firecrackers is a cherished tradition, as is exchanging sweets and gifts among friends and family. Diwali celebrations typically feature rangoli, which are geometric, floral patterns drawn on the floor using colorful powders. This year, several northern Indian states, including the capital New Delhi, are instituting partial or total fireworks bans to combat rising pollution levels during Diwali.

Buddhists, Jains and Sikhs have their own Diwali stories:

—Jains observe Diwali as the day the Lord Mahavira, the last of the great teachers, attained nirvana, which is liberation from the cycle of birth, death and rebirth.

—Sikhs celebrate Bandi Chhor Divas — a day that overlaps with Diwali — to commemorate the release of Guru Hargobind, a revered figure in the faith, who had been imprisoned for 12 years by the Mughal emperor Jahangir.

—Buddhists observe the day as one when the Hindu Emperor Ashoka, who ruled in the third century B.C., converted to Buddhism.

This year, Mattel has released its “Barbie Signature Diwali Doll” by designer Anita Dongre who wrote on Instagram that her Barbie represents “the fashion-forward modern women who wears India on her sleeve with pride.”

In contrast to her earliest iteration in 1996 who was clad in a bright pink sari or the 2012 avatar who was packaged with a “monkey friend,” Diwali Barbie is fashionably dressed in a lehnga, an ankle length embroidered skirt with motifs from Dongre’s home state of Rajasthan, a cropped blouse and vest.

This doll, priced at $40, sold out on day one on Mattel’s website.

LAS VEGAS (AP) — Andrei Svechnikov jammed in a puck on a six-on-four power play with 1:42 left to complete a furious four-goal comeback by the Carolina Hurricanes and force overtime at 4-4 against the Vegas Golden Knights on Saturday night in Game 3 of the Stanley Cup Final.

Teams that trail by at least four goals in a Cup Final game are 0-108. Now the Hurricanes have an opportunity in sudden death to become the first.

The Golden Knights seemed to have the game in hand after scoring four times in the second, including a natural hat trick by Mitch Marner.

But Jordan Martinook, Taylor Hall and Jordan Staal scored goals for the Hurricanes to turn what appeared to be a party atmosphere into a white-knuckler for the Golden Knights. Their goals, occurring 39 seconds apart, are the fastest in a Cup Final game

Marner scored the fastest hat trick in Stanley Cup Final history, igniting a four-goal second period in for the Vegas Golden Knights, who held off a furious Carolina rally to beat the Hurricanes 4-3 lead and take a 2-1 series lead.

Marner's scoring outburst came over a 6:10 stretch of the period, and he had four points in the second. He had the secondary assist on Tomas Hertl's goal midway through the period.

The last time a player had four points in a period of the Cup final occurred in 1919 when Frank Foyston of the Seattle Metropolitans pulled off that feat.

Marner nearly added to the total in the third period, but failed to capitalize on a breakaway and a penalty shot. Those missed chances came back to bite the Golden Knights.

The Hurricanes made the comeback after changing goalies to open the third, going with Brandon Bussi, who stood tall in making all nine saves. Frederik Andersen had given up those four goals on 16 shots.

Vegas' Carter Hart has made 19 stops on 23 shots.

Vegas twice thought it took the lead early in the second period, but the Hurricanes successfully challenged both goals to keep the game scoreless.

Mark Stone's goal from the slot 36 seconds into the period was overturned when Brett Howden was determined to be offside after a video review. Another review wiped off Jack Eichel's rebound goal four minutes in when Rasmus Andersson was called for goalie interference.

It's not the first time this series went against the Golden Knights.

An unsuccessful video challenge by Vegas coach John Tortorella in Game 2 on Thursday night led to a power-play goal by Jordan Staal, whose goal helped the Hurricanes rally to win 4-3 in overtime.

The series is 1-1. Teams that take a 2-1 series lead in the final went on to win the Cup 46 of 57 times, or 80.7%.

The Golden Knights received a major boost when defenseman Brayden McNabb took the ice. He took a puck in the face in the first period Thursday night at Carolina and didn't return to the game. McNabb, who had on a cage to protect his face, is Vegas' best defensive defenseman. He was on the first defensive pair with Shea Theodore.

“I wish I could say it’s shocking, but it’s not," Golden Knights captain Mark Stone said on the ABC broadcast. "Just the way he comes to the rink every day, it’s like nothing happened. He’s one of a kind. They don’t make them like that anymore, that’s for sure.”

This series has been, if anything, unpredictable.

Each team blew two-goal leads in the first two games, with the Golden Knights rallying in the opener and Hurricanes responding with a Game 2 victory in overtime.
