Flag Day commemorates June 14, 1777, when the Continental Congress determined the composition of the nation's banner: "Resolved, That the flag of the thirteen United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation.” President Woodrow Wilson issued a 1916 proclamation of June 14 as Flag Day and in 1949, President Harry S. Truman signed the formal observance into law. And it falls during Flag Week, after another congressional dictum in 1966. Details at the link in our bio. #flagday #june14
