Daylight Saving Time Ends Sunday
Many Americans will turn their clocks back one hour on Sunday as daylight saving time (DST) ends. This change brings lighter mornings and darker evenings in most states.
Who Observes Daylight Saving Time?
Almost every state observes DST, except Hawaii and Arizona. However, the Navajo Nation within Arizona does observe DST. The territories of Guam, Puerto Rico, American Samoa, the Virgin Islands, and the Northern Mariana Islands do not change their clocks.
Ongoing Debate and Legislation
The question of whether to make daylight saving time permanent continues to spark debate. Nineteen states have passed laws to keep DST year-round. Yet, the National Conference of State Legislatures (NCSL) explains that federal law does not currently allow permanent DST. Congress would need to approve such changes for states to implement them.
"Because federal law does not currently allow full-time DST, Congress would have to act before states could adopt changes." — NCSL
Public Opinion
Only 12% of U.S. adults support making daylight saving time permanent.
Visual Note
Vintage clocks, like those at the Electric Time Company in Medfield, Massachusetts, require resetting to reflect the time change.
