Every spring and fall, millions of people across the world change their clocks for Daylight Saving Time (DST), a practice that has long been part of our schedules yet raises questions every year. Is it still necessary? Why do we change our clocks, and how did this tradition begin? Let’s dive into the history, benefits, challenges, and future of DST.
The History of Daylight Saving Time
Daylight Saving Time has a curious origin story. While many believe it started to benefit farmers, DST actually began as a way to conserve energy. The idea of adjusting the clock to make better use of natural daylight was first suggested by Benjamin Franklin in 1784. Franklin noted that shifting the clocks forward would allow people to take advantage of more daylight, thus reducing the need for candles.
However, it wasn’t until the early 20th century that the concept was actually put into practice. During World War I, Germany was the first to implement DST in 1916 as a way to save fuel for the war effort. Shortly after, many other European countries, including the United Kingdom, followed suit. The United States officially adopted DST in 1918, although it was initially met with mixed reactions. After the war, DST was abandoned but was later reintroduced during World War II.
In the 1960s, the U.S. established standardized DST with the Uniform Time Act of 1966, which set consistent start and end dates across the country. Since then, there have been a few adjustments, with the current practice extending DST from the second Sunday in March to the first Sunday in November.
How Does Daylight Saving Time Work?
The logic behind DST is simple: during the warmer months, we move an hour of daylight from the morning to the evening. In the spring, we “spring forward,” setting our clocks an hour ahead, giving us more daylight in the evening. In the fall, we “fall back,” turning our clocks back an hour to standard time, providing more daylight in the morning.
The idea is that this shift allows people to enjoy more daylight after work or school, reduces the need for artificial lighting, and helps conserve energy. It also aligns our waking hours more closely with daylight hours, which many believe improves productivity and mental well-being.
Benefits of Daylight Saving Time
Daylight Saving Time has had its advocates over the years, with proponents pointing out several potential benefits:
- Energy Conservation: The original purpose of DST was to reduce energy consumption. By shifting daylight to the evening hours, DST reduces the need for artificial lighting and heating during peak hours. While the energy savings have decreased with modern lighting and HVAC technology, some studies suggest there are still slight energy savings in regions with DST.
- Increased Outdoor Activity: With more daylight in the evening, people tend to engage in outdoor activities like walking, jogging, or playing sports. This additional activity can have positive effects on both physical and mental health.
- Boost for Businesses: Retail businesses, restaurants, and other service industries often see an increase in activity during DST. The additional daylight hours can encourage people to shop and dine out after work, which can boost local economies.
- Safety Benefits: Some research suggests that DST may reduce traffic accidents, particularly in the evening when people are more likely to be on the roads. Having more daylight during the evening rush hour can improve visibility, potentially making roads safer.
The Downsides and Controversies of Daylight Saving Time
Despite these potential benefits, DST has its fair share of critics, who point to the drawbacks and disruptions caused by the time changes.
- Disrupted Sleep Patterns: Studies show that DST can disrupt our circadian rhythms, particularly during the “spring forward” transition. The loss of an hour’s sleep can lead to grogginess, decreased alertness, and even an increase in heart attacks and strokes in the days following the change.
- Limited Energy Savings: Modern lighting and climate control technologies have made the energy-saving benefits of DST negligible. In fact, some studies suggest that the increased use of air conditioning during warmer DST months might actually cancel out any energy savings from reduced lighting usage.
- Economic and Productivity Costs: DST-related fatigue can affect workplace productivity and may lead to increased workplace accidents. Studies estimate billions of dollars in productivity losses each year due to DST transitions, which can affect the economy.
- Health Concerns: Beyond sleep issues, DST has been linked to increased rates of depression, as well as seasonal affective disorder (SAD), due to the sudden shift in daylight hours. The fall transition to standard time, for instance, often leads to less evening daylight, which can negatively impact mood and well-being.
- Inconsistencies Across Regions: Not all regions observe DST, leading to confusion in time zones and scheduling. In the United States, Hawaii and most of Arizona have opted out of DST, which can complicate travel, business, and communication across state lines.
The Future of Daylight Saving Time
In recent years, there’s been growing momentum to abolish DST or make daylight saving time permanent. Many countries around the world are reconsidering the practice, and in the U.S., several states have proposed or passed legislation to either opt out of DST or make DST year-round. In 2018, the European Parliament even voted to end the mandatory biannual time change, though member states still need to agree on a unified approach.
In the United States, legislation like the Sunshine Protection Act has gained support in Congress and, if passed, could make daylight saving time permanent nationwide. Proponents argue that a permanent DST could provide year-round benefits like increased daylight for evening activities and a more consistent daily schedule without the biannual disruption.
Is It Time to Stop Changing the Clocks?
Daylight Saving Time was created for a world vastly different from the one we live in today. While the practice once offered clear benefits, modern society’s energy consumption, work patterns, and lifestyle choices have changed significantly. As research continues to reveal the physical and psychological impacts of the biannual clock change, the future of DST remains uncertain.
Whether or not DST remains a part of our future, one thing is clear: our clocks may change, but the need for balance between work, health, and the natural world is timeless.
When does the time change?
Daylight saving time ends at 2 a.m. on Sunday Nov. 3, 2024. That’s the first Sunday in November, and marks the return to standard time.
Daylight saving or savings?
While it is often referred to as Daylight Savings Time, Daylight Saving Time without the “s” at the end is the correct term.
What time do clocks ‘fall back?’
When local time reaches 2 a.m. on Nov. 3, clocks will turn backward an hour to 1 a.m.
Your smartphones, computers and smart watches will automatically adjust to the time change. But if you have appliance clocks, old-fashioned clocks or analog watches, remember to adjust those manually.

What time will the sun rise Sunday morning?
The sun will rise around 7:13 a.m. Sunday morning and set Sunday night at 5:27 p.m.
What is daylight saving time?
Daylight saving time is when “daylight” begins an hour later in the morning and lasts an hour longer in the evening, according to the National Institute of Standards and Technology.
This allows the hour of daylight to stay coordinated with the time most people are active outside. Daylight saving time is supposed to save energy, since during the warmer months the majority of people will be outside and not home, which saves energy.
When is the shortest day of the year in 2024?
The shortest day of the year marks the winter solstice, the first day of winter. This year, it will fall on Saturday, Dec. 21, 2024.
