A consortium of leaders from within the community of reason endorsed the idea of a National Day of Reason. This observance is held in parallel with the National Day of Prayer, on the first Thursday in May each year.
This year it's coming up on May 5, 2016.
Visit the website for the National Day of Reason where you can endorse reason, send a proclamation, sign a petition, find out about events and government actions, and learn more about it. You might even consider organizing your own event!
