We celebrate Flag Day to commemorate the adoption of the Stars and Stripes as the official flag of the United States, which happened on June 14, 1777. Throughout our history, the American flag has served as a symbol of freedom and opportunity that exist in this great democracy.
Both President Woodrow Wilson, in 1916, and President Calvin Coolidge, in 1927, issued proclamations of national observation of Flag Day. Though, it didn’t become official until President Harry Truman signed the joint resolution approved by the U.S. Congress August of 1949 proclaiming June 14 as Flag Day.
The U.S. Army also celebrates its birthday on this day as well.
