June 14 is celebrated as Flag Day for the United States flag adopted by the Continental Congress.
On June 14, 1777, Congress passed the Flag Resolution specifying thirteen alternating red and white stripes and thirteen white stars on a blue field. The resolution described the stars as representing a new constellation. The design reflected the thirteen states then united in the Revolutionary cause.
Flag Day is not the same as Independence Day, which is July 4, or the anniversary of the Declaration’s formal signing, primarily August 2. It commemorates the 1777 congressional resolution establishing the early national flag’s basic design.
The flag later changed as new states joined the Union. Congress added stars for new states while retaining thirteen stripes, so the modern flag has fifty stars but still has thirteen stripes. The 1777 resolution therefore remains a key link between the founding era and America250.
