According to America250 plans, the national time capsule is scheduled to be opened in 2276.
The capsule is designed to connect the United States’ 250th anniversary in 2026 with the nation’s 500th anniversary 250 years later. Its contents represent people, institutions, places, and experiences from contemporary American life.
The capsule is associated with Independence National Historical Park in Philadelphia, a site closely connected with the Declaration of Independence and the founding era. The long interval is part of the project’s purpose: future Americans will encounter artifacts created during the semiquincentennial.
This date can be confused with 2076, the 300th anniversary of independence. It is also separate from the 1976 Bicentennial time capsule, which commemorated the earlier 200th anniversary and has a different planned opening date.
