The annual observance was established in the months following the terrorist attacks of September 11, 2001. U.S. President George W. Bush signed a joint resolution of Congress into law on December 18, 2001, officially designating September 11 of each year as the day of remembrance.
The specific legislative action, formally known as Public Law 107-89, originated as House Joint Resolution 71. This resolution was introduced and approved by Congress on October 25, 2001, before being signed by the President. The statute requests that the President issue a yearly proclamation for the observance, directs that the flag of the United States be flown at half-staff, and calls for a nationwide moment of silence to honor the victims.
The creation of this day established a formal, national framework for mourning and remembering the nearly 3,000 individuals killed in the attacks. It serves as a solemn tribute to the victims, their families, and the first responders. As a national day of observance rather than a federal holiday, it encourages reflection and remembrance activities across the country without a general closure of government offices or businesses.
