(CNN) — It's almost an understatement to say that winter holiday traditions are a big deal in New York City. And after last year's subdued events, they're an even bigger deal now. Here's a look at what you need to know whether you travel there or watch on TV as well as some fun tree facts:
Viewing the ceremony in person
To see the tree lighting in person, head to 30 Rockefeller Plaza, aka 30 Rock.
It's part of Rockefeller Center, a complex of 19 commercial buildings between 48th and 51st streets and Fifth and Sixth avenues in Midtown Manhattan.
Crowds are expected to be some of the largest in Manhattan since the start of the pandemic, and officials encourage people to use to use public transportation.
You can get there by various subway routes and short walks: the B/D/F/M trains, the 1 and 6 trains and the N/Q/R trains.
The weather forecast for tonight is a temperature of about 44 degrees F (6.7 C) and cloudy conditions. The National Weather Service says there's a 50% change of rain after 10 p.m., so keep a close eye on the sky for your departure.

If you miss the lighting ceremony, you're not out of luck. The tree will be lit daily from 6 a.m. to midnight, the Rockefeller Tree Lighting website says. On Christmas Day, the tree will be lit for 24 hours. On New Year's Eve, it is lit from 6 a.m. to 9 p.m. A time hasn't been set yet for taking down the tree.
Because this is an outdoor event, there are no mask or vaccination requirements this year, a Rockefeller Center spokesperson told CNN Travel in an email.
In 2020, small groups, short viewing times and scheduled appointments were in effect as pandemic precautions.
If you can't be there in person, you can still view the spectacle.
NBC will broadcast the lighting nationally on its "Christmas in Rockefeller Center" special. That airs from 8 p.m. to 10 p.m. ET/PT Wednesday. In addition, it will simulcast live on the new Peacock streaming service. You can also catch it on streaming services that carry NBC.
"Today" co-anchors Savannah Guthrie, Hoda Kotb, Al Roker and Craig Melvin will host.
NBC says performers for the special include Alessia Cara, Harry Connick Jr., Mickey Guyton, Norah Jones, Brad Paisley, Rob Thomas, Carrie Underwood and the Radio City Rockettes.
Fun facts about the tree

The annual tree has a storied history.
The first tree went up in 1931, as the Great Depression was sinking its hooks into the city (and the rest of the country). Workers lucky enough to have a job lined up for their pay beneath it. Ceremonies around the tree became an annual affair in 1933. The lighting ceremony was broadcast for the first time on national television in 1951.
The largest tree came in 1999. It was 100 feet tall and came from Killingworth, Connecticut. In 2001, the plaza was a place of solace for the city and the nation after the 9/11 attacks, with the tree decorated in red, white and blue.
Besides pleasing the wave of humanity that passes by it each year, the tree serves a more practical purpose, too. After it's taken down in early January, the tree is donated to Habitat for Humanity and turned into lumber for homes.
A few more 2021 tree tidbits from Rockefeller Center:
-- The tree is a 79-foot (24 meter) tall Norway Spruce. It's 46 feet (13.7 meters) wide and weighs 12 tons.
-- It has more than 50,000 multicolored LED lights on about 5 miles (8 kilometers) of wire.
-- The Swarovski star on top weighs about 900 pounds (408 kilograms) and features 70 spikes covered in 3 million crystals.
