Flag Observances for June
June 14 is designated as Flag Day. It is a commemoration of the Second Continental Congress’s adoption of the flag as the national symbol of the United States in 1775. In the same session after adoption of the flag, the Congress established the “US Continental Army.” As such, the US Army celebrates June 14, 1775 as the date of its founding.
The third Sunday in June (this year June 17) is Father’s Day, a Federal holiday designated in the US Flag code as an official observance.
Title 36 United States Code, Subtitle I (Patriotic and National Observances and Ceremonies), Part A (Observances and Ceremonies), Chapter 1 (Patriotic and National Observances) lists the two days:
§ 109. Father’s Day
§ 110. Flag Day
It is at the President’s discretion to issue a proclamation for Flag Day. The week in which Flag Day appears (this year June 12-18) is designated as Flag Week.
All Americans are encouraged to fly the US Flag on Father’s Day and during Flag Week. The flag is flown full-mast unless modified by Presidential or gubernatorial proclamation.
