September 11th is the National Day of Service and Remembrance, also known as 9/11 Day. The September 11th National Day of Service and Remembrance is the culmination of efforts originally launched in 2002 by the 9/11 nonprofit 9/11 Day, with wide support by the 9/11 community and leading national service organizations. This effort first established the inspiring tradition of engaging in charitable service on 9/11 as an annual and forward-looking tribute to the 9/11 victims, survivors, and those who rose up in service in response to the attacks

The initial numbers are indelible: at 8:46 am, Tower 1 was hit, and then at 9:03 am, Tower 2. Shortly after, at 9:37am, Flight 77 crashed into the western façade of the Pentagon in Washington, D.C. – and finally, at 10:07am, Flight 93 went down in a Pennsylvania field.
