On what date is the Navy's birthday celebrated?

The Navy's birthday is celebrated on October 13, 1775. This date marks the establishment of the Continental Navy, which was formed to defend the American colonies during the Revolutionary War. The Continental Congress authorized the creation of the marine service on this date, and it is recognized as the beginning of the naval service in the United States. Celebrating Navy Day on this date honors the rich history and tradition of the U.S. Navy, as well as the dedication and sacrifices of its personnel throughout its existence.

In contrast, July 4, 1776, is Independence Day, commemorating the adoption of the Declaration of Independence. February 22, 1787, does not have significance in the context of the Navy's history, as it relates to the constitutional convention. April 15, 1794, marks the establishment of the U.S. Navy's first commissioned ships but is not recognized as the actual birthday of the Navy itself. Thus, October 13, 1775, is the correct answer to the question regarding the celebration of the Navy's birthday.
