When is the nation's birthday, also known as Flag Day?

The nation’s birthday, commonly known as Flag Day, is celebrated on June 14th. This date commemorates the adoption of the United States flag by the Second Continental Congress in 1777. It serves as a reminder of the country's values and independence, and honors the symbolism of the flag itself. While July 4th is recognized as Independence Day, marking the declaration of independence from Great Britain in 1776, Flag Day specifically focuses on the flag as a representation of the nation and its history. The other dates mentioned do not hold the same significance in relation to the flag's adoption or the ideological essence of the nation’s birthday.
