November 11 is known as Veterans’ Day in the United States and is observed to honor the service of all US military veterans living or dead.
U.S. President Woodrow Wilson first proclaimed Armistice Day in on November 11, 1919. After World War II, there was a push to expand Armistice Day to include all veterans. On May 26, 1954 President Eisenhower signed into law an act that expanded Armistice Day to include all veterans. On November 8 of that same year, Congress amended the law by simply changing the name to Veterans’ Day.
However, if November 11 falls on a Saturday or a Sunday, the official observance will be held on Monday in order to have a three-day weekend.
