What to look out for while you watch
As always, the opening ceremony will be a huge spectacle and opportunity for the host nation to showcase its history and culture.
In the US, the broadcast will be hosted by Mike Tirico and Katie Couric, who is returning to NBC for the Olympics. Tirico, who is best known for his work doing play-by-play on Monday Night Football, will be covering his first Olympic Games.
On Wednesday, Team USA announced that Erin Hamlin will be the flag bearer for the US. In the last Winter Olympics, she became the first-ever American to win a medal in singles luge. After that, the only sport the US has never medaled in is biathlon.
The US will appear near the end of the parade of nations during the opening ceremony. Traditionally, nations march in alphabetical order with to exceptions. Greece goes first and the host country goes last. That finale will be especially charged this year because South Korea and North Korea have announced that they'll march together under a unification flag.
Oh, and there will probably be fireworks. Everyone loves fireworks.
