The America250 time capsule is scheduled to remain buried for 250 years before its planned opening.
The capsule was prepared for burial in Philadelphia on July 4, 2026, the 250th anniversary of the Declaration of Independence. Its scheduled unearthing is July 4, 2276, which will mark the Declaration’s 500th anniversary. The interval between the two dates is therefore exactly 250 years.
The capsule links the 2026 celebration to a future generation rather than serving as a short-term commemorative display. Its contents are intended to preserve material connected with America250, including contributions associated with the federal government, states, territories, and anniversary programs.
This time span can be confused with the anniversary itself. The 2026 event is the 250th anniversary of independence, while the 2276 opening is planned for the 500th anniversary. The capsule’s burial location is Philadelphia, a city central to the Continental Congress and the drafting and adoption of the Declaration of Independence.
