Which date is recognized as the Army Birthday?

The Army Birthday is recognized as June 14, 1775. This date marks the establishment of the Continental Army, which laid the foundation for what would become the United States Army. The Continental Congress authorized the creation of the army to fight against British rule, and this significant moment in history is commemorated annually to honor the service and sacrifices of Army personnel throughout the years.

The other dates listed do not align with this historical milestone. For instance, October 13, 1775, pertains to the establishment of the United States Navy, while August 4, 1775, and November 10, 1775, do not represent pivotal events associated with the Army's foundation. Thus, June 14 stands out as the definitive and officially recognized Army Birthday, making it the correct choice.
