Watch The Best Happy Dances From All Over The World

Today is the International Day of Happiness, and these videos are guaranteed to make you smile

If Pharrell Williams wants us to be happy today, who are we to argue?

The singer has teamed up with the United Nations Foundation to celebrate International Day of Happiness. (That's today, in case you missed it.)

All week, Pharrell's fans from all over the world have been uploading videos of themselves dancing to his hit song "Happy" and tagging them with #HappyDay. Now the singer has selected his favourites - one from every time zone around the world.

At noon in each time zone, Pharrell posts the winning video from that area to his website.

So far we've seen some sweet dance moves from Tunisia, Brazil, Myanmar, Tokyo and many more - and we're currently watching some talented schoolgirls from the US bust a move in their classroom.

Maybe we're a a bit biased, but our favourite video is (obviously) the one from London. It features appearances from the Queen and the Duke And Duchess of Cambridge, as well as some very impressive moves by Prince Harry.

Check out a few of the videos below - and then go ahead and take some time to do your own happy dance. We promise you won't regret it.
