Many Americans will turn their clocks back one hour on Sunday as daylight saving time ends. This shift brings lighter mornings and darker evenings in most states.
At 2 a.m. local time, clocks will fall back one hour, affecting millions across the country. Some welcome the extra hour of sleep, while others find the change inconvenient.
Nineteen states have passed laws to adopt daylight saving time year-round. However, federal law currently does not allow permanent daylight saving time, so Congress must approve any nationwide changes.
"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)
Only 12% of adults in the U.S. support permanent daylight saving time.
Vintage clocks, like those at the Electric Time Company in Medfield, Massachusetts, will need resetting to match the time change.
Summary: The end of daylight saving time on Sunday will require resetting clocks across most states, while the debate over making it permanent continues due to legal and public opinion hurdles.
