On what date did the United States Bicentennial culminate in 1976?

The United States Bicentennial culminated on July 4, 1976.

That date marked the 200th anniversary of the Second Continental Congress adopting the Declaration of Independence. Although commemorative events occurred throughout 1975 and 1976, July 4 was the central national anniversary date.

The Bicentennial was not a single festival in one city. After debates over a proposed centralized exposition, federal planners emphasized locally sponsored observances across the country. Communities organized parades, exhibitions, reenactments, concerts, fireworks, and patriotic displays.

The 1976 celebration also included major national events in Philadelphia, New York, Washington, and elsewhere. Queen Elizabeth II made a state visit, the National Air and Space Museum opened its new building, and international sailing ships gathered for Operation Sail. America250 follows this earlier nationwide model for the 250th anniversary in 2026.
