As November approaches, a familiar ritual looms: the turning back of clocks. On November 2nd, most of the United States will revert to standard time, ending daylight saving time for 2025. But this annual adjustment isn’t just about losing an hour of daylight; it’s a practice increasingly challenged by science and public frustration.
Despite growing awareness of its negative impacts, and even legislative efforts to abolish it, the clock-changing cycle persists. Recent research from Stanford School of Medicine suggests a link between these biannual shifts and increased rates of stroke and obesity, highlighting a serious public health concern.
Experts at the American Academy of Sleep Medicine advocate for permanent standard time, arguing it best aligns with our natural circadian rhythms. This internal clock governs vital bodily functions, and disrupting it twice a year can have far-reaching consequences for health and safety.
The most recent attempt to break free from this cycle was the Sunshine Protection Act, a federal bill that aimed to make daylight saving time permanent. It surprisingly passed the Senate in March 2022, envisioning brighter winter evenings at the cost of darker mornings.
However, the bill stalled in the House of Representatives, ultimately failing to become law. While there was general agreement on the need to end clock changes, lawmakers couldn’t reach a consensus on whether to favor permanent daylight saving time or permanent standard time.
The core of the debate lies in understanding the difference between “standard time” and “daylight saving time.” These aren’t just labels; they represent distinct time zones, like Eastern Standard Time versus Eastern Daylight Time. Standard time is our winter baseline, while daylight saving time is the shifted schedule we use during the summer months.
Currently, federal law allows states to opt out of daylight saving time and remain on standard time year-round, a path chosen by Hawaii and Arizona (excluding the Navajo Nation). However, states are prohibited from adopting permanent daylight saving time without federal approval.
Interestingly, nineteen states have already passed legislation to switch to permanent daylight saving time, poised to act if federal law changes. These include Alabama, Colorado, Delaware, Florida, Georgia, Idaho, Louisiana, Maine, Minnesota, Mississippi, Montana, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Washington, and Wyoming.
California voters even authorized a similar law, though it remains inactive pending federal action. Kentucky and Ohio have also explored similar legislation, but those efforts stalled before reaching completion.
The 1966 federal law governing time zones essentially created a system where states can choose to stay in the dark, but can’t choose to stay in the light. This leaves many feeling trapped in a system that increasingly feels outdated and detrimental to well-being.
For those truly seeking escape, a move to a territory that doesn’t observe daylight saving time – like the U.S. Virgin Islands or Puerto Rico – offers a permanent solution. But for the vast majority, the wait for a federal resolution continues, leaving us to brace for another seasonal time shift.
