Veterans Day is a public holiday that is dedicated to honoring anyone who has served in the United States military. The holiday began as a day to remember the end of World War I and was declared a holiday by President Woodrow Wilson in 1919. Originally known as Armistice Day, the holiday became Veterans Day in 1954.
Beginning November 11th, 2015 from 0600 to 2359 & subsequent Veterans' Days, the POTUS shall illuminate the White House with the color purple .
Purple is the color that symbolizes all branches of the military, as it is the combination of Army green, Coast Guard blue, Air Force blue, Marine red and Navy blue.
This would be a fitting gesture in support of those who serve or have served by the sitting Commander In Chief.
