September 11 Day of Remembrance Act

This bill adds "September 11 Day of Remembrance" as a legal public holiday on September 11th in the list of federal holidays under Title 5 of the U.S. Code. It directly affects federal employees and government operations, requiring federal offices to close on this date. The key mechanism is a simple amendment to existing law, inserting the new holiday name after Labor Day in the list of designated public holidays. This change establishes a permanent, non-procedural observance for the anniversary of the September 11 attacks.
