September 11- National Day of Service and Rememberance.
The mission of this day is to honor the victims of 9/11 and those who rose to service in response to the attacks by encouraging all Americans and others throughout the world to pledge to voluntarily perform at least one good deed, or another service activity on 9/11 each year. In this way, the day of service hopes to create a lasting and forward-looking legacy -- annually rekindling the spirit of service, tolerance, and compassion that unified America and the world in the immediate aftermath of the 9/11 attacks.
