During the Moment of Remembrance, every person across the country is called upon to stop and remember those we lost in the September 11th attacks. The Moment of Remembrance will take place for one full minute at 10:00 a.m. Pacific Time on September 11, 2011, and cities, counties and towns, firehouses, churches and other institutions across the country are called upon to sound sirens and ring bells during that minute. These sirens and bells will be a signal for each person to stop and remember the people we lost and demonstrate the perseverance the American people have shown since that fateful day.
