U.S. Army Birthday and Flag Day
June 14
The U.S. Army’s birthday is celebrated on June 14, marking its establishment by the Second Continental Congress in 1775 to form the Continental Army, a year before the Declaration of Independence. The Army, founded with ten companies of riflemen, grew from these beginnings into the world’s most powerful land force, defending the nation through centuries of conflict and ensuring freedom, with major anniversary celebrations often featuring parades, festivals, and ceremonies on or around this date, as seen with its 250th milestone in 2025.
