National Oklahoma City Bombing Commemoration Day is observed on April 19 every year to honor the victims, survivors, rescuers, and all those affected by the 1995 Oklahoma City bombing. The commemoration takes place at the Oklahoma City National Memorial, which was dedicated on April 19, 2000, five years after the attack. The bombing, carried out by Timothy McVeigh and Terry Nichols, resulted in the deaths of 168 people and injured over 680. Remembrance services include a traditional 168 seconds of silence at 9:02 a.m., the reading of victims' names, a church service, and a charity marathon. Although the day is not recognized by presidential proclamation, it serves as a significant observance in the United States to remember the tragic event and its impact.
