un hand-washing day

I was taken aback to read the following headline on the BBC:
Millions mark UN hand-washing day.

In fact, if you click through, you’ll find it is not, as I first suspected, a day of non-handwashing, to save the world’s limited soap and water resources, but a “campaign and pledge to embrace more hygienic practices by the simple act of washing [your] hands.”

 
So, wherever you are, and whatever you’re doing today, whether working or celebrating, just make sure your hands are (UN)clean!
