U.S. toโค ‘Fall Back’ November 2nd as Daylight Saving Timeโฃ Ends
Most of the United States will revert to standard time on November 2nd, 2024, turning clocksโฃ back one โขhour. The change, occurring at 2:00 am local time, aims to align with variations in sunlight throughout โคthe year, providing an extra hour of sleep โfor many. Exceptions include Arizona (excluding some municipalities) and Hawaii, which do notโ observe โฃDaylight Saving time.
This practice originated in 1918 with the Standard Time Act,enacted by Congress during World War I toโ conserve โenergy. While attempts have been made to repeal the law over the years, the Uniform Time Act โขofโ 1966 formalized Daylight Savingโค Time nationwide, allowing states to โขopt-out.
The shift means residents will gain an hour of darkness in the evening but lose an hour of daylight โขin โขthe morning, with the reverse occurring โonโ March 8, 2026, when Daylight Saving Time resumes. U.S. territories like Puerto Rico, the Virginโค Islands, Guam, and American Samoa โฃdo not โขparticipate โฃin the โฃtime change due to minimal seasonal variationโข in sunlight.
“In Puerto โRico the โvariation in solarโฃ energy is minimal,”โ explained Vรญctorโฃ Manuel Jimรฉnez โAcevedo, geologist and founder of the Puerto Rico Meteorological โฃCenter. “we almost always have the same amount of light, there is no dramatic reduction in sunlight.”
Legislation โknown as theโข Solar Protection Law, reintroduced in Congress in January 2025, seeks to โeliminate Daylight Saving Time altogether, but has yet to be brought to a vote.
