September 11, 2026 marks 25 years since the terrorist attacks that killed nearly 3,000 people in New York, Washington D.C., and Pennsylvania. This milestone anniversary is being observed not just through ceremonies, but through newly released public records, health programs, and opportunities for people to serve and remember.
The White House officially proclaimed September 11, 2026 as Patriot Day and directed federal buildings nationwide to fly flags at half-staff. The presidential proclamation documents 2,977 victims. In New York City, the FDNY recorded 343 firefighters who died that day.
But here's what makes the 25th anniversary different from earlier ones: the story hasn't ended. The Port Authority installed a new memorial at the World Trade Center site in 2026, honoring employees killed in the attacks. New York City opened more than 170,000 pages of government records concerning the city's response, air quality measurements, and health concerns that emerged after September 11.
The records include material concerning health concerns, air quality, the city's response, the Harding Memo, the '68 boxes' and World Trade Center 7.
The health aspect remains urgent. First responders—firefighters, police, construction workers who spent weeks at Ground Zero—developed illnesses years after the attacks. The FDNY released a document called "Resilience" that specifically examines ongoing health effects among responders. FDNY continues to document serious health effects among members who participated in the rescue and recovery efforts.
The American government recognizes this. The VA's National Cemetery Administration scheduled September 12 service activities at 144 participating cemeteries nationwide. New York City organized public remembrance events.
