Daylight Saving Time (DST) will officially end on Sunday, November 2, 2025, at 2 a.m. local time, when clocks are turned back by one hour. This shift marks the return to standard time for most of the United States, with the next transition back to DST scheduled for March 2026. The end of DST means that people will gain an extra hour of sleep on the night of November 2, but it also brings noticeable changes in daily life. Evenings will become darker earlier, while the sun will rise earlier in the morning, which can shift people’s daily routines.

The transition out of DST has long been a topic of debate due to its impact on health. Research has shown that the sudden time change can disrupt people’s sleep patterns and biological rhythms. The body’s internal clock, also known as the circadian rhythm, is thrown off by the clock change, leading to potential issues like sleep deprivation and difficulty adjusting to new schedules. Some studies have even suggested that the shift in time may increase the risk of certain health problems, such as heart attacks, strokes, and sleep disorders.

There are also significant social and economic implications of switching between DST and standard time. For many people, the end of DST means a longer period of darkness in the evenings, which can affect mood and overall well-being. The shift can also have practical consequences for industries such as transportation and healthcare, where timing is crucial.

While there have been calls to abolish the clock change and adopt permanent standard time or permanent DST, such changes have yet to be enacted in the United States. Efforts like the Sunshine Protection Act, which would make Daylight Saving Time permanent, have stalled in Congress. Despite this, some states and territories have chosen to remain on standard time year-round. Hawaii and most of Arizona are examples of U.S. states that do not observe DST and instead stick to standard time throughout the year. Similarly, several U.S. territories, including Puerto Rico and the U.S. Virgin Islands, also do not participate in the clock shift.

As the debate over Daylight Saving Time continues, many experts urge a reevaluation of its benefits and drawbacks, especially given the growing body of research on its impact on public health. Some believe that eliminating the biannual clock change and sticking to one time year-round could improve people's health and well-being, while others argue that it could lead to its own set of challenges. For now, the clock change remains in effect, and millions of Americans will experience the familiar ritual of "falling back" in November.
