Wednesday, June 14 marked the 240th anniversary of the day (June 14, 1777) when the Second Continental Congress adopted the Stars and Stripes as the national emblem of the United States.
In 1916, President Woodrow Wilson issued an official proclamation to mark the date as Flag Day. However, Flag Day is not a federal holiday.
The flag took its current form with 13 stripes and 50 stars on July 4, 1960 after the admission of Alaska and Hawaii to the Union.
The U.S. Army also celebrates June 14 as its birthday with the establishment of the Continental Army on June 14, 1775.
