June 14, 1777. Today is Flag Day! On May 30, 1916, President Woodrow Wilson issued a presidential proclamation establishing a national Flag Day on June 14. Many Americans celebrate Flag Day by displaying the Red, White and Blue in front of homes and businesses.

The following year (1894) 300,000 school children participated in Flag Day celebrations promoted by the Illinois American Flag Day Association.
