what president issue flag day
President Wilson proclaims Flag Day, June 14, 1916. In 1916, President Woodrow Wilson issued a proclamation that officially established this day â June 14 â as Flag Day. Congress followed up in 1949 by enacting a statute that officially recognized Flag Day. Flag Day, however, is not an official federal holiday. While the statute leaves it to the presidentâs discretion to proclaim its observance, every president since Wilson has done so.
