The National Moment of Remembrance is an annual event that asks Americans, wherever they are at 3:00 p.m. local time on Memorial Day, to pause for a duration of one minute to remember those who have died in military service to the United States.
The time 3 p.m. was chosen because it is the time when most Americans are enjoying time off from work for the national holiday. The Moment was first proclaimed in May 2000 for Memorial Day that year, and was put in law by the United States Congress in December 2000.
Many of us who are trumpet players will be playing Taps at 3:00 pm local time. Perhaps you will hear one or more of us.
