America’s Time Capsule, buried during the 2026 semiquincentennial, is scheduled to reopen in 2276.
The capsule was designed as a record of the United States at its 250-year milestone. Its planned opening date is 250 years after its burial, linking the America250 commemoration to the nation’s future 500th anniversary.
The capsule was associated with Philadelphia and Independence National Historical Park, a location chosen for its connection to the Declaration of Independence and the founding era. Its contents were intended to preserve objects and messages representing contemporary American life.
The year 2276 is not a random distant date: it is exactly 500 years after 1776. It is therefore intended to connect the semiquincentennial with a future quincentennial celebration.
