Keep the later sunsets, drop the twice-a-year clock switch

4 min readLast updated September 25, 2026

Why it matters

308 House members voted to stop the clock switch, and H.R. 139 now needs the Senate. It would keep every U.S. time zone on daylight saving time all year, ending the March and November resets, while Hawaii, most of Arizona, and other places that already skip daylight time could keep the clocks they use now.

H.R. 139, the Sunshine Protection Act of 2025, runs about a page and does one thing. It would stop the spring-forward, fall-back cycle by keeping every U.S. time zone on daylight saving time for the entire year.

It gets there in two moves. It repeals the federal rule that sets the seasonal switch, then redefines each time zone one hour later. Eastern time, for example, would sit four hours behind Coordinated Universal Time all year instead of dropping back to five hours every November.

The trade-off shows up in winter. Sunsets would come an hour later than they do now, and so would sunrises. In cities on the western edge of a time zone, such as Detroit or Indianapolis, late-December sunrise would land around 9 a.m.

Places that already skip daylight saving time, including Hawaii and most of Arizona, would not be forced to change. They could adopt the new permanent time or keep the clock they use today. If Arizona stays put, it would match Pacific time year-round instead of only in summer.

The bill creates no grants, fines, or new agency. The work lands on anyone who keeps a schedule: airlines, broadcasters, school districts, and software that still expects a twice-yearly switch.

H.R. 139 Bill Summary

What H.R. 139 actually does.

1

The March and November clock changes stop

The bill repeals the federal provision that sets the seasonal daylight saving period, so there is no longer a spring-forward or fall-back date.

2

Summer time becomes the only time

Each federal time zone is redefined one hour later, all year. Eastern would sit four hours behind Coordinated Universal Time, Central five, Mountain six, and Pacific seven.

3

Places that already opted out get to choose

States or areas that exempted themselves from daylight saving time before the bill becomes law, such as Hawaii and most of Arizona, can adopt the new permanent time or keep the time they used before.

4

Every zone moves, not just the lower 48

The bill rewrites all of the federal time-zone definitions, including the zones covering Alaska, Hawaii, and U.S. territories.

Who benefits from H.R. 139?

Anyone who dreads the March time change

The spring switch takes an hour of sleep overnight and throws off routines for days. Under the bill, it would never happen again.

People who want daylight after work or school

Winter sunsets would move an hour later, leaving more light for errands, kids' outdoor sports, and the drive home.

Arizona residents and businesses

If Arizona keeps its current clock, it would line up with California and the rest of Pacific time all year, ending the half-year scheduling mismatch.

Businesses that schedule across the country

Airlines, broadcasters, and national employers would stop resetting timetables and shift schedules twice a year.

Who is affected by H.R. 139?

Early risers, shift workers, and kids at the bus stop

Winter sunrise would come about an hour later by the clock, so more morning commutes and school drop-offs would happen in the dark.

People on the western edge of a time zone

They would see the latest sunrises. In places like Detroit or Indianapolis, late-December sunrise would come around 9 a.m.

School districts

Some may revisit start times or bus routes to deal with darker winter mornings.

Software makers and IT teams

Calendars, scheduling systems, and devices that assume a seasonal switch would need updates to the new time-zone rules.

Hawaii, Arizona, and other opted-out areas

They would need to decide whether to adopt the new permanent time or keep the clock they have now.

H.R. 139 Common Questions

Did H.R. 139 pass?

It passed the House 308-117 on July 14, 2026, but it is not law yet. The bill now sits with the Senate Commerce Committee, and the Senate has to pass it before it can go to the President.

Does H.R. 139 make daylight saving time or standard time permanent?

Daylight saving time. Your clock would stay on the summer setting all year, so you'd never fall back in November or spring forward in March.

What time would the sun rise in winter under permanent daylight saving time?

About an hour later than today. In cities on the western edge of a time zone, like Detroit or Indianapolis, late-December sunrise would come around 9 a.m. Winter sunsets would move an hour later too.

Would Arizona and Hawaii have to change their clocks?

No. Places that already skip daylight saving time could keep their current clocks or adopt the new permanent time. If Arizona stays put, it would match Pacific time all year.

When would the clock changes stop if H.R. 139 becomes law?

The bill sets no delayed start date, so it would take effect once signed. If that happened during daylight saving time, clocks would simply never fall back.

Has the U.S. tried permanent daylight saving time before?

Yes. During the 1974 energy crisis, Congress put the country on year-round daylight time. Dark winter mornings made it unpopular, and Congress reversed it before the year was out.

Didn't the Senate already pass the Sunshine Protection Act?

The Senate passed an earlier version by unanimous consent in March 2022, but the House never voted on it and it expired. H.R. 139 is a new bill, so the Senate has to act again.

Who opposes making daylight saving time permanent?

Some sleep-medicine groups, including the American Academy of Sleep Medicine, argue permanent standard time better fits the body's natural clock. In the House, 117 members voted no.
