Hug an Atheist Day
the first Friday in June (since 2009)
William Bermudez in 2009
Hug an Atheist Day was started by William Bermudez in 2009 as a parody of other Facebook groups that were popping up at the time that encouraged hugging people. He called for people to run up and hug atheists, or anyone that is a nonbeliever in general, whether they are an agnostic, skeptic, secular humanist, or have other similar views.
How to Observe Hug an Atheist Day
To celebrate the day one just needs to run up and hug as many nonbelievers as possible. You don't even have to be a nonbeliever yourself to do this!
