I've started an Event Spore page for MLK Day, hoping we can add all of the events here of global significance tied to observances of the day this year:

Please add content or edit, or participate on the talk page.
Also, I think we should set up a Wikimedia Commons photo upload campaign for this year:
I welcome you to join in!
Thanks,
