The United States Army's 250th anniversary was marked on June 14, 2025.
The date reflects the Continental Congress’s creation of the Army on June 14, 1775, one year before the Declaration of Independence. That anniversary is also associated with Flag Day, which occurs annually on June 14 in the United States.
A military parade and celebration took place in Arlington, Virginia, and Washington, D.C. The event was part of the broader lead-up to the United States Semiquincentennial, but it marked the Army’s own 250-year history rather than the nation’s July 4, 2026 anniversary.
This distinction matters because the Army’s birthday and the country’s birthday fall on different dates. The Army was established in 1775; the Declaration of Independence was adopted in 1776.
