TheNational Day of Reason is asecularcelebration forhumanists,atheists,secularists, andfreethinkers.[1][2] The day is celebrated annually on the first Thursday in May, in response to thestatutory observance of aNational Day of Prayer in theUnited States, which many atheist and secular groups deem unconstitutional.[3] The purpose of the National Day of Reason is to "celebratereason—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."[4] The National Day of Reason is also meant to help build community among thenon-religious in the United States.[5]
The National Day of Reason was created by theAmerican Humanist Association and the Washington Area Secular Humanists in 2003.[6] In addition to serving as a holiday forconstitutionalists andsecularists, the National Day of Reason was created in response to the perceivedunconstitutionality of theNational Day of Prayer.[4] According to the organizers of the National Day of Reason, the National Day of Prayer, "violates theFirst Amendment of theUnited States Constitution because it asksfederal,state, andlocal government entities to set aside tax dollar supported time and space to engage in religious ceremonies".[6]
In 2005, the New York City–based Center for Atheism began to strongly advocate for observers of the National Day of Reason to celebrate in a positive manner.[7] They decided to donate blood as a group in order to make a "public statement about the life-affirming ideas of nonbelievers."[7] Also beginning in 2005, another alternative supported by some interfaith groups has been the renaming of the National Day of Prayer as the National Day of Prayer and Reflection.
The National Day of Reason has taken some time to gain popularity. Over time, however, more local and state governments have been giving the Day of Reason official recognition.[8] In 2011 and 2012, RepresentativePete Stark supported a proclamation in support of the National Day of Reason in theUnited States House of Representatives.[5] For the first time, aresolution to honor the National Day of Reason was introduced in the U.S. House of Representatives.[9] The resolution, U.S. House Resolution 228, was proposed by RepresentativeMike Honda on April 29, 2015.[10] Another resolution to designate the National Day of Reason was sponsored by RepresentativeJared Huffman in 2018.[11]

Several organizations associated with the National Day of Reason have organizedfood drives andblood donations, while other groups have called for an end to prayer invocations at city meetings.[12][13][14] Other organizations, such as the Oklahoma Atheists and theMinnesota Atheists, have organized local secular celebrations as alternatives to theNational Day of Prayer.[15] Additionally, many individuals affiliated with theseatheistic groups choose to protest theNational Day of Prayer.[16]
Some politicians have supported the National Day of Reason. InOmaha, Nebraska, MayorJean 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."[17] City governments who affirm the National Day of Prayer have also been asked to consider affirming the National Day of Reason as well.[18]
