### United States

In the United States, the Navy League of the United States organized the first Navy Day in 1922, holding it on October 27 because it was the birthday of 26th President Theodore Roosevelt (1858–1919, served 1901–1909), who was a naval enthusiast/promoter of sea power and former assistant Secretary of the Navy just before the Spanish–American War of 1898. Although meeting with mixed reviews the first year, in 1923 over 50 major cities participated, and the United States Navy sent a number of its ships to various port cities for the occasion. The 1945 Navy Day was an especially large celebration, with 33rd President Harry S. Truman (1884–1972, served 1945–1953), reviewing the returning home American fleet in New York Harbor after victory in World War II.
In 1949, Louis A. Johnson, (1891–1966, served 1949–1950), second Secretary of the newly merged and created Department of Defense, directed that the U.S. Navy's participation occur on newly established Armed Forces Day for the unified/coordinated uniformed services in May, although as a private civilian organization, the Navy League was not affected by this directive, and continued to organize separate Navy Day celebrations as before. In the 1970s, historical research found that the "birthday" of the earlier Continental Navy during the American Revolutionary War (1775–1783), was determined to be October 13, 1775, and so Chief of Naval Operations Admiral Elmo R. Zumwalt worked with the Navy League to define October 13 as the new date of Navy Day. However, Navy Day in the United States is still largely recognized as October 27, while October 13 is marked as the Navy Birthday. The period between these two dates constitute a festive period of celebrations of the birth of the Navy.
