What name did the United States use for its 200th-anniversary celebrations in 1976?

The United States called its 200th-anniversary celebrations the United States Bicentennial.

The Bicentennial commemorated two centuries since the Declaration of Independence in 1776. Celebrations took place throughout 1976, with parades, exhibitions, public ceremonies, historical programs, and special designs appearing on stamps, coins, and other national symbols.

Philadelphia hosted major events because of its connection to the Continental Congress, the Declaration, and Independence Hall. Washington, D.C., and communities across the country also organized observances, making the Bicentennial a nationwide rather than single-city commemoration.

America250 follows the Bicentennial by 50 years. The terminology changes with the milestone: centennial means 100 years, sesquicentennial means 150 years, bicentennial means 200 years, and semiquincentennial means 250 years. These labels are often confused because they describe different anniversary intervals.
