Doh! I solved it.
Attached phone to Mac, then selected it In iTunes. Went to the sync settings. Tap Info button at the top, then scroll all the way down to Advanced. Under Replace Information on this iPhone, check the Calendars box. I sync'd it and went to my iPhone Calender app. Clicked on the Calendars button in the upper left corner and then selected the ones I wanted and hit Done. Back to normal.
Now to figure out my iCloud mess. That's another post.
