The 11th hour of the 11th day of the 11th month. Veterans Day, also known as Remembrance Day in other parts of the world, was first observed in 1919 as Armistice Day as a way of remembering those who died in World War I. Later it was expanded to all veterans. Thank you to our veterans for their service to our country. Below is an excerpt from What Have We Learned, Charlie Brown?.
