In Romania, Navy Day is a national holiday that takes place on August 15.
In Ukraine Navy Day is a professional holidays that is celebrated on every first Sunday of July. The commemoration was established in 1996 (then to be celebrated August 1). Till 2012 the day was celebrated on August 1. From 2012 till 2015 Ukraine had the same date for its Navy Day as Russia and the Soviet Union (like Russia, Ukraine is a former Soviet republic); the Soviet Union introduced its Navy Day in June 1939; the date was chosen because of a connection with the day the Battle of Gangut took place. On 24 August 2014 Ukrainian President Petro Poroshenko speeched that Ukraine should not celebrate the holidays of the "military-historical calendar of Russia" but "We will honor the defenders of our homeland, not someone else's". On 12 June 2015 a Presidential decree by Poroshenko moved Ukraine's Navy Day to every first Sunday of July.
The term is also used in Britain to mean an open day at a dockyard such as HMNB Portsmouth, when the public can visit military ships and see air displays, roughly along the lines of an American Fleet Week. The Royal Navy's equivalent of "Navy Day" is Trafalgar Day, which is celebrated on 21 October.
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 President Theodore Roosevelt, who was a naval enthusiast. 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 President Harry S. Truman reviewing the fleet in New York Harbor.
In 1949, Louis A. Johnson, secretary of the newly created Department of Defense, directed that the U.S. Navy's participation occur on Armed Forces Day in May, although as a civilian organization the Navy League was not affected by this directive, and continued to organize Navy Day celebrations as before. In the 1970s, the "birthday" of the Continental Navy was found to be October 13, 1775, and so CNO 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.
