At long last, our favorite day of the year has arrived: National Dance Day! Even though we know all of your lives are all dance, all the time, there's still something special about having an entire day devoted to the greatest thing ever. (And we especially love to see how everyone celebrates on social media!) If you aren't hyped yet, then you will be after watching the official 2016 National Dance Day choreo video, with some of our favorite "SYTYCD" all-stars (and Mackenzie Ziegler) leading the way. Check it out below, and make sure to tag us in all of your adventures on Instagram. Happy dancing!
