In a formal announcement, the City of Chicago has declared that American flags will be flown at half-staff on September 11, 2024, in observance of Patriot Day, which commemorates the 23rd anniversary of the 9/11 terrorist attacks. This day serves as a significant reminder of the lives lost during the attacks on the World Trade Center, the Pentagon, and United Airlines Flight 93. Established by a joint resolution passed in December 2001, Patriot Day calls for a national moment of silence and encourages citizens to engage in activities that honor the victims. The resolution specifically mandates that flags be lowered to half-staff for the entire day as a mark of respect. This observance not only reflects on the tragedy but also emphasizes the resilience and unity of the American people in the face of adversity.

Local government agencies are instructed to comply with the flag-lowering directive as a show of solidarity. The announcement serves as a reminder of the ongoing significance of 9/11 in American history and its impact on national security and policy. Citizens are encouraged to participate in the observance and reflect on the profound loss experienced by many families across the nation.
