Why Are We Still Changing Our Clocks for Daylight Saving Time?
America continues to adjust its clocks twice a year, except for Hawaii and Arizona, where the tradition does not apply. On Sunday, November 2, most states will "fall back" by setting clocks back one hour at 1 a.m., typically done before bed on Saturday night.
Current Changes in Daylight
As the northern hemisphere moves into its darkest part of the year, daylight hours gradually shorten. Since the Summer Solstice, sunlight has been decreasing steadily. For example, on November 2 in San Diego, the sun sets as early as 4:56 p.m., with sunrise around 6:07 a.m., according to the National Oceanic and Atmospheric Administration (NOAA).
"The hours of sunlight have been steadily shrinking since the Summer Solstice (the first official day of summer)."
By Thanksgiving Day on November 27, the sun sets even earlier at around 4:43 p.m. On December 21, the Winter Solstice, recognized as the shortest day and longest night of the year, sunset will occur as early as 4:47 p.m.
"The hours of daylight will continue to dwindle, coming to an apex on the day of the Winter Solstice, Dec. 21, at which point the sun will set as early as 4:47 p.m."
Additional Notes
- Daylight saving time allows more evening daylight during warmer months but results in earlier sunsets in winter.
- Traditionally, "falling back" means setting clocks one hour earlier in autumn to gain more morning light.
- Thanksgiving timing combined with earlier sunsets and heavier meals can encourage more sleepiness.
Summary: Despite modern debates, most of the U.S. still observes daylight saving time, shifting clocks annually to adjust for changing daylight patterns in accordance with natural solar cycles.
