Coast Guard Day is observed on August 04, 2021. Coast Guard Day is held every year to commemorate the founding of the United States Coast Guard as the Revenue Marine on 4 August, 1790, by then Secretary of the Treasury Alexander Hamilton. On that date, Congress, guided by Hamilton, authorized the building of a fleet of the first ten Revenue Service cutters, whose responsibility would be enforcement of the first tariff laws enacted by Congress under the Constitution.
Coast Guard Day is primarily an internal activity for active duty and reserve Coast Guardsmen, civilian employees, retirees, auxiliarists, and dependents, but it does have a significant share of interest outside the service. Coast Guard units throughout the United States usually plan picnics and informal sport competitions together with family and friends on Coast Guard Day. Grand Haven, Michigan, also known by act of Congress as Coast Guard City, USA, annually sponsors the Coast Guard Festival the week of August 4. (With material from: Wikipedia)
