Flag Day (United States) Flag Day is not an official federal holiday. Title 36 of the United States Code, Subtitle I, Part A, CHAPTER 1, § 110 is the official statute on Flag Day; however, it is at the president's discretion to officially proclaim the observance. On June 14, 1937, Pennsylvania became the first U.S. state to celebrate Flag Day as a state holiday, beginning in the town of Rennerdale. New York Statutes designate the second Sunday in June as Flag Day, a state holiday. Perhaps the oldest continuing Flag Day parade is in Fairfield, Washington. Beginning in 1909 or 1910, Fairfield has held
United Nations Day resolution (United Nations Resolution 2782) declaring that United Nations Day shall be an international observance or international holiday and recommended that it should be observed as a public holiday by United Nations member states. The first event called "United Nations Day" was a World War II Allies' day of solidarity and military parades launched by US President Franklin D. Roosevelt tied to US Flag Day on June 14, 1942, six months after the Declaration by United Nations. It was observed in New York City as the "New York at War" parade, in London, and by the Soviet and Chinese governments.
