What is the birthday of the U.S. Flag?

The birthday of the U.S. Flag is recognized as June 14, 1777. This date is significant because it marks the adoption of the first official flag by the Continental Congress, which specified that the flag would have 13 stripes to represent the 13 original colonies, along with a blue field of stars. This act formalized the symbolic representation of the nation and its values.

Other dates listed, such as July 4, 1776, are historically important for the Declaration of Independence, while January 1, 1780, and December 20, 1790, do not hold any significance related to the flag's history or design. Thus, June 14 not only marks a key moment in flag history but is also celebrated as Flag Day in the United States.
