Many Americans will set their clocks back one hour on Sunday as daylight saving time (DST) ends. This change brings lighter mornings and darker evenings in most states.
While some people appreciate the extra hour of sleep, others find the adjustment inconvenient. This annual shift also affects circadian rhythms.
Nineteen states have passed laws to keep daylight saving time year-round. However, because federal law currently prohibits permanent DST, Congress must approve any nationwide change.
"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 keeping daylight saving time all year long.
Vintage clocks at the Electric Time Company in Medfield, Mass., need manual resetting to reflect the time change on Sunday.
Summary: The annual end of daylight saving time requires resetting clocks and adjusting routines, with potential changes dependent on Congressional action amid mixed public views.
