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
Columbus Day as an official state holiday, though many mark it as a "Day of Observance" or "Recognition" and at least four do not recognize it at all. Most states that celebrate Columbus Day will close state services, while others operate as normal. San Francisco claims the nation's oldest continuously existing celebration with the Italian-American community's annual Columbus Day Parade, which was established by Nicola Larco in 1868, while New York City boasts the largest, with over 35,000 marchers and one million viewers. As in the mainland United States, Columbus Day is a legal holiday in the U.S. territory of Puerto Rico.
