Flag Day is celebrated in the United States on June 14 each year. This day commemorates the adoption of the national flag, known as the Stars and Stripes, by the Second Continental Congress in 1777. It serves as a reminder of the country's history and the symbolism of the flag, which represents unity and freedom. In addition to the U.S., several other countries also observe their own versions of Flag Day, often celebrating the history and significance of their national flags. Activities may include parades, ceremonies, and educational events to promote awareness of the flag's importance and the values it embodies.
