Atheist Day 2024

Date: March 23rd, 2024


  • Origins: Atheist Day originated from a humorous story circulated online in 2003. The fictional tale involved an atheist suing the government because atheists didn’t have a designated day, unlike many religions. The story gained traction, leading to the unofficial holiday.
  • Evolution: Over time, Atheist Day gained recognition from secular organizations like the American Humanist Association. It’s become a day to celebrate the diversity of beliefs and promote the rights of atheists and non-believers.


  • Celebrating Atheism: Atheist Day is a day for atheists to openly celebrate their beliefs and for the non-religious community to build connections.
  • Awareness: It raises awareness about atheism and challenges the idea that atheism is simply the absence of belief, highlighting it as a distinct worldview.


  • There are no official Atheist Day rituals or celebrations, but atheist groups might hold events or gatherings to promote social connection and understanding.

Celebration Ideas:

  • Gather with friends and family who share your non-religious beliefs.
  • Attend a meetup group that focuses on atheism to meet new people and share ideas.
  • Read books about atheism to expand your understanding of the world and challenge your beliefs.

National Day of Reason: In the United States, the National Day of Reason on the first Thursday in May serves a similar purpose of promoting secularism and raising awareness about the separation of church and state.


  • The green circle is a common symbol for atheism, symbolizing completeness, unity, and infinity, as well as the vitality of the atheist community.
  • Other symbols include the letter A in a circle, representing atheism, and the Darwin Fish, a parody of the Jesus fish symbol used by Christians, combining the Ichthys shape with the silhouette of a fish, referencing Charles Darwin’s theory of evolution.

Conclusion: Atheist Day is an annual observance on March 23rd for atheists, agnostics, and freethinkers to celebrate their beliefs, raise awareness about atheism, and promote understanding and acceptance among people of different beliefs.
