H.R. 139: US would make daylight saving time permanent year-round

01 — The Text

What.

Makes daylight saving time (DST) the permanent standard across the U.S., eliminating the twice-yearly clock changes.
Allows states currently exempt from DST to keep standard time in their areas if they choose.
Removes the seasonal switch between standard and daylight saving time effective upon enactment.

02 — The Stakes

Americans gain one extra hour of evening daylight year-round; sleep and health researchers debate whether permanent DST disrupts circadian rhythms.
Business groups support stable schedules; farmers and some rural communities prefer standard time alignment with sunrise.
States lose flexibility to follow local preferences, though exempted areas retain limited choice.

03 — The Path

House passed it 308-117 on July 14, 2026. Senate Commerce Committee received it July 15; no floor vote scheduled yet.
Senate must debate and vote; presidential signature required to become law.
Contact your senator to express support or opposition before committee advances the bill.
