When is the Navy's official birthday?

The Navy's official birthday is celebrated on 13 October 1775. This date marks the establishment of the Continental Navy, which was created to support the American colonies in their rebellion against British rule during the Revolutionary War. The Continental Congress authorized the procurement of ships and the enlistment of sailors on this date, laying the groundwork for what would eventually evolve into the United States Navy.

The other dates mentioned do not correspond to the founding of the Navy. For example, 1 January 1776 does not represent a significant naval milestone, while 4 July 1776 is known for the adoption of the Declaration of Independence, and 17 September 1776 does not correspond to any key naval events. Understanding these historical dates helps clarify the significance of 13 October 1775 as the foundation of the Navy, marking its enduring legacy in American military history.
