Annual secular celebration in the United States

The National Day of Reason is a secular celebration for humanists, atheists, secularists, and freethinkers. The day is celebrated annually on the first Thursday in May, in response to the statutory observance of a National Day of Prayer in the United States, which many atheist and secular groups deem unconstitutional. The purpose of the National Day of Reason is to "celebrate reason—a concept all Americans can support—and to raise public awareness about the persistent threat to religious liberty posed by government intrusion into the private sphere of worship." The National Day of Reason is also meant to help build community among the non religious in the United States.

The National Day of Reason was created by the American Humanist Association and the Washington Area Secular Humanists in 2003. In addition to serving as a holiday for constitutionalists and secularists, the National Day of Reason was created in response to the perceived unconstitutionality of the National Day of Prayer. They decided to donate blood as a group in order to make a "public statement about the life affirming ideas of nonbelievers." In 2011 and 2012, Representative Pete Stark supported a proclamation in support of the National Day of Reason in the United States House of Representatives. The resolution, U. S. House Resolution 228, was proposed by Representative Mike Honda on April 29, 2015. Another resolution to designate the National Day of Reason was sponsored by Representative Jared Huffman in 2018.

Several organizations associated with the National Day of Reason have organized food drives and blood donations, while other groups have called for an end to prayer invocations at city meetings. Other organizations, such as the Oklahoma Atheists and the Minnesota Atheists, have organized local secular celebrations as alternatives to the National Day of Prayer. Additionally, many individuals affiliated with these atheistic groups choose to protest the National Day of Prayer. Some politicians have supported the National Day of Reason. In Omaha, Nebraska, Mayor Jean Stothert signed a proclamation supporting the National Day of Reason and urging all citizens to "promote the development and application of reason. Her proclamation never once mentions a non belief in God or Prayer." City governments who affirm the National Day of Prayer have also been asked to consider affirming the National Day of Reason as well.
