On or around September 17 of each year, Hillsdale College and the Kirby Center host a Constitution Day Celebration, a day-long event that includes panels, debates, and speeches on issues and controversies related to the Constitution and the principles of free government. The first annual Constitution Day Celebration was held in 2010, in conjunction with the dedication of the Kirby Center building. Past speakers have included Congressman Paul Ryan and journalists George Will and Charles Krauthammer.
