You can watch the opening ceremony live at 6 am. I think you should visit nbc’s website for the schedule, they are using like 4 channels. I got a couple of their apps.
If you’ve Android, you can download their TV app for free and watch online.
I did visit the site - that’s where I was looking, specifically at the page listing the sports and dates. In past years, they’d show Opening Ceremonies at the top, and Closing at the bottom. It’s probably on the website somewhere, but the Lying Press is only going to get brief fractions of my attention.
