On what date will America250 mark the United States semiquincentennial?

America250 will mark the United States semiquincentennial on July 4, 2026.

The date reflects the 250th anniversary of the adoption of the Declaration of Independence in 1776. July 4 became the date associated with American independence because the Second Continental Congress adopted the Declaration on that day.

The anniversary is commonly called America’s 250th, the United States Semiquincentennial, or America250. The word “semiquincentennial” combines terms meaning half of 500, or 250 years. It is the successor to the national bicentennial celebrated in 1976.

The date can be confused with July 2, 1776, when Congress approved the Lee Resolution declaring the colonies independent. July 4, however, is the date shown on the Declaration and the date used for the national Independence Day observance.
