Why Are We Still Changing Our Clocks for Daylight Saving Time?
In the United States, aside from Hawaii and Arizona, clocks are set back one hour each fall as daylight saving time ends. This annual tradition, known as "falling back," usually occurs before bedtime on a Saturday night, with clocks moving back at 1 a.m. on Sunday.
The Changing Daylight Hours
Since the Summer Solstice, the number of daylight hours has been steadily decreasing as the northern hemisphere moves into its darkest days. For example, by November 2, the sun will set in San Diego as early as 4:56 p.m., according to the National Oceanic and Atmospheric Administration (NOAA).
Sunrise times also change, with the sun rising at 6:07 a.m. around this time, urging solar enthusiasts to make the most of available daylight.
Approaching the Shortest Day
The reduction in daylight continues as the Winter Solstice approaches. By December 21, the shortest day and the longest night of the year, sunset will occur as early as 4:47 p.m., NOAA reports.
"You know what that means -- daylight saving time is coming to an end!"
On Thanksgiving Day, November 27, the sun will set around 4:43 p.m., often signaling the onset of early night and after-effects like tiredness from holiday meals rich in carbohydrates.
How Daylight Saving Time Affects Us
- Most Americans except those in Hawaii and Arizona adjust clocks twice yearly.
- The time change aims to make better use of daylight during shorter winter days.
- Sunset and sunrise times shift noticeably as seasons progress toward winter.
- The tradition continues largely due to historical, social, and energy considerations.
Understanding these shifts helps people plan their days better during the darker months.
"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."
Adjusting clocks remains a practical way to align daily activities with daylight availability in much of the country.
