More than 1 million people were on-hand in Times Square to celebrate 2018 on what was the coldest New Year’s Eve in the city in 100 years and the second-coldest on record.

Mayor Bill de Blasio and Tarana Burke, the founder of the #MeToo hashtag, started the countdown for the famous New Year’s Eve Ball a minute from midnight, sending the ball on its minute-long journey to ring in the new year.

Revelers, who were packed into security pens in areas designated for viewing the ball drop in Times Square, were wrapped in as many layers as possible. The temperature continuously dipped on New Year’s Eve, falling to 9 degrees around 11 p.m., with a wind chill around -5.

The coldest New Year's Eve was in 1917, when the mercury dropped to 1 degree. 

“I’m freezing to death,” said one reveler who was bundled up.

“It’s beautiful out!” said another reveler who traveled from Canada, saying New York City’s weather was like summer compared to the frigid conditions in his hometown.

Emergency personnel were on-hand to monitor people for signs of hypothermia, according to Joseph Esposito, the commissioner of the New York City Emergency Management Department.

People who attended the celebrations were flanked by extra tight security in the wake of two terror attacks in the city in less than six weeks during autumn.

But from performances from stars like Mariah Carey, to the sight of the sparkling New Year’s Eve Ball, the cold and security did not dampen most spirits.

After the party, the city's Sanitation Department got right to work cleaning up all the confetti, paper, and other debris left behind.

Meanwhile, other cities across the U.S. ushered in the new year with their own celebrations.

Down in Key West, thousands turned out to watch the famous shoe drop.

Drag queen Sushi was lowered in the giant red high-heel from the Bourbon Street Pub.

In Nashville, Music City rang in 2018 with the annual dropping of the 15-foot-tall red music note followed by fireworks.

And Seattle kicked off the new year with its own dazzling fireworks show from the iconic Space Needle.

The colorful show went on for about eight minutes.
