It has been 97 years since the United States first celebrated Veterans Day. On Nov. 11, 1919, the holiday, which originated as Armistice Day, marked the first anniversary since the end of World War I.
Congress passed a resolution in 1926 marking Armistice Day as an annual observance. Twelve years later, November 11 was officially a national holiday.
But it wasn’t until President Dwight D. Eisenhower signed legislation in 1954 that the name was changed to Veterans Day as a way to honor all people who had served in any U.S. war.
