Patriot Day is established on September 11 of each year to commemorate the terrorist attacks on the United States on September 11, 2001, and to honor the individuals who died or were injured in the attacks, the courageous first responders and other individuals who gave their lives to save others during the attacks, and the brave individuals who continue to serve and protect our nation, including military personnel, first responders, and health care providers. The governor shall direct that the Alaska flag be flown at half-mast on that day. Patriot Day may be observed by suitable observances and exercises by civic groups and the public.
