The Army birthday is June 14. On June 14, 1775, the Continental Congress authorized companies of riflemen to serve the United Colonies for one year, and the U.S. Army counts its founding from that day. The Army is the oldest U.S. military service, and on June 14, 2026, it turns 251. The Army birthday falls on the same date as Flag Day.
Why is the Army birthday on June 14?
The Army birthday is on June 14 because on that day in 1775 the Continental Congress first raised troops in the name of all the colonies. Congress called for 6 companies of riflemen from Pennsylvania, 2 from Maryland and 2 from Virginia to join the siege of Boston. The rifle companies are often called the first units of the Continental Army, according to the U.S. Army War College. The next day, June 15, 1775, Congress chose George Washington as commander in chief.

Is the Army birthday the same as Flag Day?
