On what date is America’s Time Capsule scheduled to be unearthed?

America’s Time Capsule is scheduled to be unearthed on July 4, 2276. That date will mark the 500th anniversary of the Declaration of Independence.

The capsule was prepared for burial in Philadelphia as part of the America250 commemoration. Its planned opening date deliberately looks beyond the 2026 anniversary: the contents are intended to give people in the distant future a snapshot of the United States at its 250-year point.

Philadelphia was chosen because it was central to the founding story. The Declaration was adopted and signed there, and Independence Hall remains one of the most important locations connected with the American Revolution and the creation of the United States.

The date can be confused with 2176, which would be 400 years after independence, or with 2276’s broader significance as the nation’s quincentennial. The capsule’s planned opening is exactly 250 years after its 2026 burial date.
