Is June 9 a holiday we don't know about?

Facebook is telling us that today (June 9) is a "holiday which may affect office hours."

Well, we have to work, so we're not sure what they're talking about.

Have you seen this today on Facebook? We looked around and couldn't find ANYTHING about it. Any ideas?

Let's call it "Get the Z App Day!" If you do, you might even win a $100 gift card to Dunkin' Donuts!
