Update: I've put a temporary hack in place that fixes most of the schedule data, but not all real-time seems to be work. I'd still advice you take a look at the KCM holiday schedule page below.
The schedule data I get from King County Metro does not properly take into account Memorial Day Holiday scheduling, which unfortunately means incorrect schedules and no real-time data today. Super frustrating, I know!
The best I can advise is to have you take a look at King County Metro's holiday scheduling page: goo.gl/5M2Dj
Holiday scheduling has been broken in the data I get from King County Metro for a while now. If you are as frustrated by this as I am, please let King County know: goo.gl/DLSa8
