While most know that Veterans Day honors those who have served in the military, the meaning behind its exact date (November 11) may not be so familiar. Here's the back story:

U.S. President Woodrow Wilson first proclaimed an Armistice Day for November 11, 1919 to commemorate the "eleventh hour of the eleventh day of the eleventh month" in 1918 when the armistice was signed between the Allies of World War I and Germany for the cessation of hostilities on the Western Front.

 The United States Congress passed a concurrent resolution seven years later on June 4, 1926, requesting the President issue another proclamation to observe November 11 with appropriate ceremonies. An Act (52 Stat. 351; 5 U.S. Code, Sec. 87a) approved May 13, 1938, made the 11th of November in each year a legal holiday; "a day to be dedicated to the cause of world peace and to be thereafter celebrated and known as 'Armistice Day'."

In 1953, an Emporia, Kansas shoe store owner named Al King had the idea to expand Armistice Day to celebrate all veterans, not just those who served in World War I. King had been actively involved with the American War Dads during World War II. He began a campaign to turn Armistice Day into "All" Veterans Day. The Emporia Chamber of Commerce took up the cause after determining that 90% of Emporia merchants as well as the Board of Education supported closing their doors on November 11, 1953, to honor veterans. With the help of then-U.S. Rep. Ed Rees, also from Emporia, a bill for the holiday was pushed through Congress. President Dwight Eisenhower signed it into law on May 26, 1954.

Congress amended this act on November 8, 1954, replacing "Armistice" with Veterans, and it has been known as Veterans Day since.

In many parts of the world people take a two-minute moment of silence at 11:00 a.m. as a sign of respect for the roughly 20 million people who died in the war, as suggested by Edward George Honey in a letter to a British newspaper although Wellesley Tudor Pole established two ceremonial periods of remembrance based on events in 1917.

In the UK, beginning in 1939, the two-minute silence was moved to the Sunday nearest to 11 November in order not to interfere with wartime production should 11 November fall on a weekday. Both Armistice Day and Remembrance Sunday are commemorated formally in the UK.
