World Humanist Day - June 21


World Humanist Day is celebrated every year on June 21. It’s a way to spread information, and combat misinformation about humanism as a philosophical life stance and means to affect change in the world.

The Encyclopedia Britannica says humanism originally was called “humanitas.” It meant the development of human virtue, in all its forms, to its fullest extent. The term thus implied qualities as such as “understanding, benevolence, compassion, mercy—but also much more assertive characteristics as fortitude, judgment, prudence, eloquence, and even love of honor. Consequently, the possessor of humanitas could not be merely a sedentary and isolated philosopher or man of letters but was of necessity a participant in active life.”


Look for and attend a local lecture or discussion on or about June 21. Topics for discussion can range from the global, such as talks about the activities of the Humanists International, to the individual, such as open forums where people share their personal pathways to Humanism.

In the late 1980s-early 1990s, the AHA and then the IHEU passed resolutions declaring the Summer Solstice to be World Humanist Day.

  • 2013, the first National Humanist Day was organized in The Netherlands.
  • June 21, which is the same day or close to the same day as the summer solstice. The solstice event has echoes of ancient communal gatherings, as well as reflecting humanity’s deepening scientific understanding of our world, and being an event that, by its nature, is shared globally at the same moment in the calendar.
