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

Daylight Saving Time Ends Sunday

Many Americans will turn their clocks back one hour on Sunday as daylight saving time ends. This change means lighter mornings and darker evenings for most states.

Who Observes Daylight Saving Time?

All states observe daylight saving time except Hawaii and Arizona. However, the portion of the Navajo Nation in Arizona does observe it. U.S. territories including Guam, Puerto Rico, American Samoa, the Virgin Islands, and the Northern Mariana Islands do not change their clocks.

Year-Round Daylight Saving Time Legislation

Nineteen states have passed laws to adopt daylight saving time throughout the year. However, federal law currently does not allow permanent daylight saving time, so congressional approval is required before these changes can be implemented.

"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

Public Opinion

Only 12% of U.S. adults support permanent daylight saving time according to recent data, reflecting ongoing debate over whether to keep the time change or not.

Additional Details

Vintage clocks, such as those at the Electric Time Company in Medfield, Massachusetts, will need to be reset to reflect the time change on Sunday.

Author's summary: Daylight saving time ends Sunday, prompting a nationwide clock reset amid ongoing debate and limited public support for making the change permanent.
