NATIONAL DAY OF REASON – First Thursday in May

NATIONAL DAY OF REASON – First Thursday in May
(Last Updated On: February 3, 2023)


National Day of Reason is observed each year on the first Thursday in the month of May. The observance originated in 2003 in response to the perceived unconstitutional National Day of Prayer. According to the organizers of the day, the National Day of Prayer, “violates the First Amendment of The United States Constitution because it asks federal, state and local government entities to set aside tax dollar supported time and space to engage in religious ceremonies.”

The First Amendment of the United States Constitution reads:

“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”

The day is a secular observance for atheists, humanists, and secularists set to coincide with the National Day of Prayer. It acknowledges that celebration occurs for those who do not recognize God or an established religion or faith.
