Daylight Saving Time Nears End

WASHINGTON — Daylight saving time will end for 2025 on Sunday, Nov. 2, at 2 a.m., when clocks “fall back” one hour. The change will give most people an extra hour of sleep, bringing earlier sunrises and nightfall before 7 p.m. Clocks will not “spring forward” again until March 2026.

Congress has repeatedly considered legislation to make daylight saving time permanent, but such measures have consistently failed to become law. Without changes, Americans will continue adjusting clocks twice a year.

Daylight saving time, first introduced in the U.S. during World War I under the Standard Time Act of 1918, was intended to reduce energy use by extending daylight hours. The measure, then known as “war time,” lasted from spring to fall and also established the nation’s five time zones.

The Uniform Time Act of 1966 created a nationwide standard for daylight saving time, originally running from the last Sunday in April to the last Sunday in October. In 2005, President George W. Bush signed a law extending the observance from the second Sunday in March until the first Sunday in November.

Arizona and Hawaii do not observe daylight saving time, though under federal law states may choose to remain on standard time year-round. The U.S. has also implemented daylight saving time year-round twice — during World War II and again in 1974 during an energy crisis.

In 2022, the U.S. Senate unanimously approved a bill that would have made daylight saving time permanent, but the measure failed to advance in the House.
