When was the Army first established?

The Army was first established on June 14, 1775, which is recognized as the date when the Continental Congress created the Continental Army during the American Revolutionary War. This formation was essential for coordinating military efforts in the struggle against British rule, laying the groundwork for what would become the United States Army. The significance of this date is commemorated each year as the Army's birthday, marking the start of its enduring legacy and commitment to national defense.

The other dates listed pertain to important moments in American history, such as the Declaration of Independence on July 4, 1776, which marked the formal assertion of independence from British rule, but they do not represent the establishment of the Army itself. Similarly, January 1, 1781, and December 25, 1775, lack the historical context associated with the founding of the Army, making June 14, 1775, the definitive answer.
