World Humanist Day and Solstice - International Humanist and
Ethical Union This is another annual event that could be used to
promote Humanism and Freethought. "World Humanist Day is
celebrated annually on June 21 throughout the world. "Marking
the day is a way to spread information and combat misinformation
about the positive aspects of Humanism as a philosophical life
stance and means to effect change in the world. "The origin was
in the 1980s, when several state chapters of the American
Humanist Association (AHA) began celebrating World Humanist
Day."
