In the tradition of reporting on undervalued national holidays, we bring your attention to the one occurring today: National High Five Day. The holiday is observed on the third Thursday of April each year, and celebrates the power of the popular hand-based greeting, which apparently also turns 30 this year.
Those of you wanting to celebrate en masse — but probably only in spirit — can join the other 1500 people taking part on Facebook.
And the extremely dedicated can visit this UK-based website, “The home of the high five on the internet!”, which pays tribute to the gesture year round.
