Semiquincentennial
The formal historical term for America250’s 250th anniversary is semiquincentennial.
The word combines “semi,” meaning half, with “quincentennial,” meaning a 500th anniversary. Together, the parts describe half of five hundred years, or 250 years. The term is used for the anniversary of the United States Declaration of Independence.
The event is also described as the United States Semiquincentennial. Other labels have appeared, including sestercentennial, quarter millennium, and bisesquicentennial, but semiquincentennial is the official name most closely associated with the federal commemoration.
The previous major anniversary was the bicentennial in 1976, marking 200 years. The next major 100-year milestone after 2026 will be the tricentennial in 2076.
