"Resolved, that the Flag of the thirteen United States shall be thirteen stripes, alternate red and white; that the Union be thirteen stars, white on a blue field, representing a new constellation."
National Flag Day is in celebration of the American flag. On June 14th, 1777, Continental Congress approved the design of America's national flag. Since 1916, when President Woodrow Wilson issued a presidential proclamation establishing a national Flag Day on June 14, Americans have commemorated the adoption of the Stars and Stripes by celebrating June 14th as Flag Day. Prior to 1916, many localities and a few states had been celebrating the day for years. Congressional legislation designating that date as the national Flag Day was signed into law by President Harry Truman in 1949; the legislation also called upon the president to issue a flag day proclamation every year.
