Who knew? The Winter Olympics start today!

Pay no attention to the relentless promos for the XXIII Olympic Winter Games opening ceremony airing on NBC on Friday night. Things actually get underway Thursday morning in PyeongChang, South Korea.

Yep, Thursday morning. Which is actually Wednesday night in the good old U.S. of A.

PyeongChang is 14 hours ahead of the Eastern Time Zone, including Atlanta. Throw in the fact that there are 102 medal events being contested in 15 sports, including lots of preliminary rounds, and it makes sense competition would have to start before the Olympics’ “official” opening on Friday.

What makes no sense is the event that starts it all there Thursday morning : Mixed doubles curling, making its Olympic debut with round robin matches, including one pitting the American brother-sister team of Matt and Becca Hamilton taking on the OAR ("Olympic Athletes from Russia") pair.

Again, that's Wednesday night here, and  you can stream it live on NBCOlympics.com and the NBC sports app starting at 7:05 p.m. (Cable channel NBCSN will also air the curling starting at midnight).

In all, NBC Olympics will live stream 1,800 hours from these Games and televise 2,400 hours of coverage (no, not all of them figure skating, smart alecks!) on four networks.

It's a bounty for fans, but also confusing as heck. Go here to read our article laying out everything you need to know about watching these Olympics with or without a TV.
