This observance is held in parallel with the National Day of Prayer, on the first Thursday in May each year. The goal of this effort 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 website is co-sponsored by the American Humanist Association and the Washington Area Secular Humanists.

<!--break-->The Day of Reason also exists to inspire the secular community to be visible and active on this day to set the right example for how to effect positive change. Local organizations might use “Day of Reason” to label their events, or they might choose labels such as Day of Action, Day of Service, or Rational Day of Care. The important message is to provide a positive, useful, constitutional alternative to the exclusionary National Day of Prayer.
