What anniversary will the United States mark on July 4, 2026, in the America250 celebration?

The United States will mark its 250th anniversary on July 4, 2026, in the America250 celebration.

The anniversary commemorates the Declaration of Independence, which was adopted by the Second Continental Congress in 1776. July 4 became the date associated with American independence because the Declaration was formally adopted on that day.

The term for a 250th anniversary is semiquincentennial. The event follows earlier national milestones, including the centennial in 1876, the sesquicentennial in 1926, and the bicentennial in 1976.

America250 is the name commonly used for the congressional commission and its nationwide commemorative efforts. Its planning began with legislation creating the United States Semiquincentennial Commission in 2016. The celebration is therefore both a historical anniversary and a modern program of events, exhibitions, educational projects, and commemorative issues.
