The 1776 Declaration of Independence and the America250 anniversary in 2026 are separated by 250 years.
The arithmetic is 2026 minus 1776, which equals 250. America250 uses that interval because its central historical reference is the Declaration’s adoption by the Second Continental Congress in 1776.
The calculation is straightforward, but anniversary language can cause confusion. The Declaration was adopted in 1776, while the United States Constitution was drafted in 1787 and ratified in 1788. America250 is not primarily a 250th anniversary of the Constitution; it commemorates the independence milestone.
The date also explains the naming sequence. Two hundred years after 1776 came the Bicentennial in 1976. Two hundred fifty years after 1776 produces the Semiquincentennial in 2026, while three hundred years will be marked by the Tricentennial in 2076.
