From teeming Times Square in New York City to a once-isolated Asian country celebrating its first public New Year's Eve countdown in decades, the world looked to the start of 2013 with hope for renewal after a year of economic turmoil, searing violence and natural disasters.

Fireworks, concerts and celebrations unfolded around the globe to ring in New Year late Monday and into Tuesday morning, and, for some, to wring out the old.

"With all the sadness in the country, we're looking for some good changes in 2013," Laura Concannon, of Hingham, Mass., said as she, her husband, Kevin, and his parents took in the scene in bustling Times Square on Monday.

A blocks-long line of bundled-up revellers with New Year's hats and sunglasses boasting "2013" formed hours for the first ball drop in decades without Dick Clark, who died in April. One of the crystal panels on the ball was engraved with his name.

Security in Times Square was tight, with a mass of uniformed police and plainclothes officers assigned to blend into the crowd. With police Commissioner Raymond Kelly proclaiming that Times Square would be the "safest place in the world on New Year's Eve," officers used barriers to prevent overcrowding and checkpoints to inspect vehicles, enforce a ban on alcohol and check handbags.

Syracuse University student Taylor Nanz, 18, said she and a friend had been standing in Times Square since 1:20 p.m. ET Monday. They hadn't moved from their spot because "if you leave, you lose your place," she said, shivering behind an iron barricade with a clear view of One Times Square, the building where the crystal ball hovered.

"It's the first time — and the last time," she said.

In Canada, annual outdoor festivities across the country featured musical and other acts at popular partying locations such as:

• Toronto's downtown Nathan Phillips Square outside city hall.
• Queen Victoria Park in Niagara Falls, Ont.
• Vancouver's Robson Square.
• Montreal's Place Jacques-Cartier.

In Rome, Pope Benedict XVI celebrated New Year's Eve with a vespers service in St. Peter's Basilica to give thanks for 2012 and look ahead to 2013. He said that despite all the death and injustice in the world, goodness prevails.

Fireworks light up iconic skylines

Elsewhere, lavish fireworks displays lit up skylines in Sydney, Hong Kong and Shanghai. In the United Arab Emirates city of Dubai, multicoloured fireworks danced early Tuesday up and down the world's tallest building, the Burj Khalifa. In Russia, spectators filled Moscow's iconic Red Square as fireworks exploded near the Kremlin. In Rio de Janeiro, revellers dressed head-to-toe in white as dictated by Brazilian tradition flooded onto Copacabana beach for a concert.

Organizers said about 90,000 people gathered in a large field in Rangoon, Burma, sometime referred to as Myanmar, for their first chance to do what much of the world does every Dec. 31 — watch a countdown. The reformist government that took office in 2011 in the country, long under military rule, threw its first public New Year's celebration in decades.

"We feel like we are in a different world," said Yu Thawda, a university student who went with three of her friends.

Parts of Europe held scaled-back festivities and street parties, the mood a bit restrained — if hopeful — for a 2013 that is projected to be a sixth straight year of recession amid Greece's worst economic crisis since the Second World War. About 22,000 revellers in the Madrid square celebrated the arrival of the new year under umbrellas as rain fell steadily.

London, the often soggy British capital, was dry and clear, though, as the familiar chimes of the clock inside the Big Ben tower counted down the final seconds of 2012 and a dazzling display of fireworks lit the skies above Parliament Square. People cheered as the landmarks were bathed in the light of the display, which included streamers shot out of the London Eye wheel and blazing rockets launched from the banks of the River Thames.

There were impromptu fireworks displays throughout much of London as people remembered a year that saw Olympics glory, the Queen's diamond jubilee and the announcement that Prince William and the former Kate Middleton are expecting their first child — welcome news that offset some of the economic gloom.

To the north in Scotland, 85,000 people gathered near the base of Edinburgh Castle for the wild Hogmaney celebration, helped by five soundstages featuring a number of top bands.

Some India sites cancel festivities

Elsewhere, the atmosphere of celebration was muted with concern.

Hotels, clubs and other sites in New Delhi, the Indian capital, canceled festivities after the death of a rape victim on Saturday touched off days of mourning and reflection about women's safety. In the Philippines, where many are recovering from devastation from a recent typhoon, a health official danced to South Korean rapper Psy's "Gangnam Style" video in an effort to stop revelers from setting off huge illegal firecrackers, which maim and injure hundreds of Filipinos each year.

And even in Times Square, some revellers checked their cellphones to keep up with news of lawmakers' efforts to skirt the fiscal cliff combination of expiring tax cuts and across-the-board spending cuts that threatened to reverberate globally. And the elementary school massacre in Newtown, Conn., and Superstorm Sandy mingled into the memories of 2012.

"This has been a very eventful year, on many levels," Denise Norris said as she and her husband, the Rev. Urie Norris, surveyed the crowd seeking to jam Times Square for a countdown show with Ryan Seacrest as host and musical acts including Taylor Swift, Carly Rae Jepsen, Neon Trees, Flo Rida and Pitbull.

About a block away, Army Sgt. Clint Evanoff waited in a black suit, red vest and red tie to get into Times Square with a couple of his friends from his unit at Fort Drum, N.Y. Evanoff, 20, is scheduled to leave for Afghanistan, his first deployment, in about two weeks.

Looking ahead to the new year, "I'm just hoping to make it back," he said.

Elsewhere, too, hopes for 2013 were a mix of personal and political. In Boston, communications writer and editor Colin O'Brien, 25, said he was optimistic that the nation had realized it was time to make tough decisions about its finances and policy and that there might be "more common ground than people are willing to admit or accept." In Harrisburg, Pa., warehouse worker Adam Gassner, 43, had more internal goals: "hoping to continue to get myself back on my feet."
