Flag day commemorates the adoption of the flag of the United States, which happened on June 14th in 1777 byresolution of the Second Continental Congress. The United States Army also celebrates the Army Birthday on this date.

The week of June 14 is designated as "National Flag Week." During National Flag Week, the president will issue a proclamation urging U.S. citizens to fly the American flag for the duration of that week. The flag should also be displayed on all government buildings. Some organizations hold parades and events in celebration of America's national flag and everything it represents.
