Daylight saving time ends Sunday. Here's what to know

Daylight Saving Time Ends on Sunday

Love it or hate it, many Americans will turn their clocks back one hour on Sunday as daylight saving time ends. This change means lighter mornings and darker evenings in most states.

Who Observes Daylight Saving Time?

Almost all states observe daylight saving time except for Hawaii and Arizona. However, the part of the Navajo Nation located in Arizona does observe it. U.S. territories such as Guam, Puerto Rico, American Samoa, the Virgin Islands, and the Northern Mariana Islands do not change their clocks.

Legislation and Debate

Currently, 19 states have passed laws to keep daylight saving time year-round. However, federal law does not permit permanent daylight saving time, so Congress must 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." — National Conference of State Legislatures (NCSL)

Mixed Reactions to the Time Change

Some people welcome the extra hour of sleep gained during the fall change, while others find the adjustment disruptive. The time shift affects both clocks and human circadian rhythms nationwide.

Additional Facts

Vintage clocks at the Electric Time Company in Medfield, Massachusetts, also require resetting.
