It was November 11, 1918, the end of “the war to end all wars.” The following year, President Woodrow Wilson proclaimed November 11 as the first commemoration of Armistice Day, saying "To us in America, the reflections of Armistice Day will be filled with solemn pride in the heroism of those who died in the country’s service and with gratitude for the victory, both because of the thing from which it has freed us and because of the opportunity it has given America to show her sympathy with peace and justice in the councils of the nations." In 1954, it became Veterans Day.
This is not a day about war or about loss of life. Today honors military veterans regardless of whether they served during a time of conflict or peace, and it isn't about those who perished in the line of duty (Memorial Day honors those people). Today is for all persons who served in the United States Armed Forces. It used to feature parades, and speeches, and special tributes to military personnel. These days retail stores use it as an excuse for a sale. One positive thing is that more and more businesses do special things for veterans on this day. Numerous restaurants across the country are giving away from meals to veterans today, for example.
You'll see a lot of mention on social media today about veterans, and certainly it's a very good thing to join in that. Remember they who served in our military. Say thank you to a vet!
