Resolution criteria

This market will resolve to YES if a federal law in the United States making Daylight Saving Time (DST) permanent year-round (thereby eliminating the biannual clock change in favor of permanent DST) is officially enacted on or before August 28, 2028.

• Definition of "Enacted": A bill is considered enacted once it is signed into law by the President, passed over a presidential veto, or allowed to become law without a signature. The actual implementation date (when the clocks officially stop changing) does not need to occur before August 28, 2028, as long as the law authorizing permanent DST has been signed/enacted.

• Scope: This applies to the Sunshine Protection Act (e.g., H.R. 139) or any other federal legislation that achieves the same nationwide outcome of making daylight saving time permanent. If a bill is enacted that makes standard time permanent instead, this market resolves to NO.

• Source of Truth: Official legislative actions and statuses recorded on Congress.gov will serve as the primary source of truth.

• Closing Time: If no such federal legislation has been enacted by 11:59 PM Eastern Time on August 28, 2028, the market will resolve to NO.

Background

The biannual clock change in the United States is regulated by the federal Uniform Time Act of 1966, which permits states to observe year-round standard time but forbids them from implementing year-round daylight saving time without federal approval. While 19 states have passed legislation or resolutions to adopt permanent DST, these trigger clauses cannot take effect until federal law is amended.

Legislative efforts to transition to permanent DST have seen renewed momentum. In May 2026, the language of the Sunshine Protection Act was integrated into a larger legislative vehicle, the Motor Vehicle Modernization Act, and voted out of the House Energy and Commerce Committee. Similar past attempts, including a version of the Sunshine Protection Act that passed the Senate by unanimous consent in 2022, have historically failed to pass both chambers of Congress and reach the president's desk.
