When do the 2018 Winter Olympics start (and end)?

Well, that snuck up fast.

With the Super Bowl still dominating most sports coverage, NBC is quickly shifting gears to focus its efforts on the 2018 Winter Olympics, taking place this year in Pyeongchang, South Korea.

The opening ceremony, hosted by NBC Sports' Mike Tirico and former Today show host Katie Couric, will air on a delay on NBC at 8 p.m. EST on Friday. NBC, for the first time, will be streaming the opening ceremony, which will air at 6 a.m. EST on NBCOlympics.com and on the NBC Sports app.

But Olympics fans won't have to wait until Friday. The competition actually will start Wednesday night, when U.S. siblings Matt and Becca Hamilton will face off in the debut of mixed doubles curling. NBCSN will also air coverage of downhill training runs for men's alpine skiing.

First competition: Mixed doubles curling

Start time: Wednesday, Feb. 7, at 11 p.m. EST

TV channel: NBCSN

Streaming: NBCOlympics.com, NBC Sports app

South Korea is 14 hours ahead of the East Coast. But the time difference works in NBC's favor during the Games themselves, allowing the network to air its prime-time coverage live across the country for the first time. Figure skating will air live in prime time on 12 of the 18 nights, and skiing will be shown live 11 nights.

On Thursday night, two-time U.S. men's figure skating champion Nathan Chen is expected to lead team USA on the first day of NBC's prime-time coverage, which will begin at 8 p.m. Headlining NBC's coverage that night is figure skating, qualifying in the men's and women's moguls competitions, and qualifying in men's ski jumping.

The Olympics will continue until the closing ceremony on Sunday, Feb. 25, which will air on a delay on NBC. The network hasn't yet decided whether it will also livestream the closing ceremony, but Mark Lazarus, chairman of NBC Broadcasting and Sports, has said "in all likelihood, we will."
