Recognizing September 11, 2021, as a "National Day of Service and Remembrance".

House Resolution 639 is a commemorative measure that officially designates September 11, 2021, as a "National Day of Service and Remembrance." The resolution encourages Americans to honor the victims and survivors of the 2001 terrorist attacks by participating in community service projects and acts of kindness.

The resolution also serves as a formal tribute to the first responders and citizens who provided aid in New York City, Northern Virginia, and Shanksville, Pennsylvania. While it does not create new laws or government programs, it provides a framework for citizens to transform the anniversary of the attacks into a day of national unity and charitable action.
