When was the current 50-star flag adopted?

The current 50-star flag was adopted on July 4, 1960. This flag design was created after Hawaii became the 50th state of the United States, officially admitted on August 21, 1959. The update to the flag incorporated a star for Hawaii, marking a significant moment in the country’s history as it completed the 50-star iteration of the flag. The timing of the adoption on July 4 aligns with Independence Day, symbolizing national unity and pride.

In contrast, other dates mentioned do not accurately reflect the adoption of the current flag. For example, July 4, 1959, is close to Hawaii's admission but does not account for the time needed to finalize the flag's design and officially adopt it. June 14, 1965, and July 4, 1976, also do not pertain to the changes made in the flag’s star count, with 1965 focusing on flag etiquette and 1976 commemorating the United States' bicentennial with various celebrations but not any flag modification.
