Daylight Saving Time Ends in 2025: Experts Debate Permanent Standard Time

As of November 1, 2025, the United States is preparing for the end of daylight saving time. On November 2, 2025, at 2 a.m. local time, clocks will fall back one hour, marking the return to standard time until March 8, 2026.

The biannual clock change has long been a source of debate, with many experts arguing that the transition can disrupt the body's natural circadian rhythm and lead to health issues. Research suggests that permanent standard time is better aligned with natural sunlight and human biology, as the morning light helps regulate the body's internal clock.

The fall back in 2025 will give people an extra hour of sleep, but it can also affect their daily routines and sleep patterns. Shift workers and those who already lack sufficient sleep may find the adjustment particularly challenging. The change can also be difficult for individuals with seasonal affective disorder, as the shorter daylight hours can trigger the condition.

Despite the potential drawbacks, some people enjoy the extra hour of rest that comes with the fall back. However, the twice-yearly clock changes have led to growing calls for the U.S. to adopt a permanent standard time, which could provide more consistent sleep patterns and better align with natural circadian rhythms.
