Why Are We Still Changing Our Clocks for Daylight Saving Time?
America continues to adjust clocks twice a year due to the tradition of daylight saving time, which shifts time to make better use of daylight during the year. In the northern hemisphere, as the days grow shorter approaching winter, this tradition remains in practice across most states.
When Does the Change Occur?
On Sunday, November 2, most Americans, except residents of Hawaii and Arizona, will set their clocks back by one hour at 1 a.m., marking the end of daylight saving time. This is commonly known as "falling back," typically done before going to bed on the preceding Saturday.
Impact of Shorter Days
- Since the Summer Solstice, daylight hours have steadily decreased.
- 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 on that day is expected at 6:07 a.m., signaling shorter daylight periods.
Notable Dates and Their Effects
- On Thanksgiving Day, November 27, the early sunset will occur at 4:43 p.m.
- The approaching winter days, combined with heavy carbohydrate meals, can promote a deep and restful sleep.
- Daylight hours will continue to shrink until the Winter Solstice on December 21, which marks the shortest day and longest night of the year.
- On December 21, the sun in San Diego will set as early as 4:47 p.m., also according to NOAA.
"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., according to NOAA."
Despite the inconvenience, daylight saving time persists due to tradition and the coordination required to end it statewide, such as in California.
Author's Summary: Daylight saving time remains active in most states, including California, to adjust for shrinking daylight hours during winter, with key dates marking early sunsets and shorter days.
