Why Are We Still Changing Our Clocks for Daylight Saving Time?
In the United States, most states except Hawaii and Arizona will set their clocks back by one hour on Sunday, November 2, marking the end of daylight saving time. At 1 a.m., time will shift backward in a tradition commonly known as "falling back," usually done before going to bed on Saturday night.
The daylight hours have been steadily decreasing since the Summer Solstice, the first official day of summer. 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). Early sunsets will continue, reaching 4:43 p.m. on Thanksgiving Day, November 27.
Daylight will keep shrinking until the Winter Solstice on December 21, the shortest day and longest night of the year, when the sun sets at around 4:47 p.m., NOAA reports. For those who cherish sunlight, it is best to enjoy the sun when it rises early at 6:07 a.m.
"At that point, time will automatically move backward to 1 a.m. This tradition is known as the time change in which we 'fall back' and generally set our clocks before bed on Saturday."
"The hours of sunlight have been steadily shrinking since the Summer Solstice (the first official day of summer)."
Summary
Daylight saving time ends in early November, as the U.S. shifts clocks back to adjust for shorter daylight hours leading to the winter solstice.
