America250 marks the United States’ 250th anniversary in 2026.
The anniversary is calculated from 1776, the year associated with the Declaration of Independence and the creation of the United States as an independent nation. Adding 250 years to 1776 gives 2026, making July 4, 2026, the central anniversary date for the national commemoration.
The celebration is formally known as the United States Semiquincentennial. America250 is the public-facing name used for the nationwide commemorative effort, while the anniversary itself is also called the 250th anniversary of American independence.
This date can be confused with the 250th anniversary of other American institutions or cities. America250 specifically concerns the nation’s independence milestone, not the founding anniversary of every place or organization in the United States.
