When Do Clocks Go Back? Daylight Saving Time Explained

Ever wondered when to adjust your clocks? In the United States, we “fall back” and turn our clocks back one hour, marking the end of Daylight Saving Time (DST). This occurs on the first Sunday of November. This change gives us an extra hour of sleep, but it can also cause some confusion. Let's delve into the details of DST, including when it happens, why we do it, and what it means for you.

Key Takeaways

• Clocks in the U.S. fall back (turn back one hour) on the first Sunday of November.
• This marks the end of Daylight Saving Time, giving you an extra hour of sleep.
• The practice is intended to make better use of daylight.
• Not all states observe DST; Arizona (excluding the Navajo Nation) and Hawaii do not.
• The specific date and time for changing your clocks can vary slightly each year.

Introduction

Daylight Saving Time (DST) is the practice of setting clocks forward one hour from standard time during the spring and summer months and then changing them back again in the fall. The idea is to make better use of daylight. The most familiar aspect of DST is the time change that occurs twice a year. This change often sparks questions about when DST begins and ends, why it exists, and how it affects our daily lives. This article will provide a comprehensive guide to understanding DST in the United States, including its history, impact, and current status. — General Conference 2025: Dates, Speakers, And What To Expect

What & Why

The Purpose of Daylight Saving Time

• Maximize Daylight: The primary goal of DST is to make the most of the daylight hours. By shifting the clocks forward in the spring, we align our waking hours with the daylight hours, giving us more usable daylight in the evenings. Historically, this meant less need for artificial light, saving energy.
• Energy Conservation: While the energy-saving benefits of DST are debated, the original intention was to reduce energy consumption by decreasing the use of electric lights. However, the impact on energy consumption is complex and has been studied extensively, with mixed results.
• Economic Benefits: Some argue that DST boosts economic activity. Longer daylight hours in the evening encourage people to engage in outdoor activities, which can benefit businesses related to recreation, tourism, and retail.

When Does the Clock Go Back?

In the United States, the clock falls back on the first Sunday of November at 2:00 AM local time. This means that at 2:00 AM, clocks are turned back to 1:00 AM. This time change marks the end of DST and the return to standard time. — USPS Ground Advantage Cubic: A Complete Guide

History of Daylight Saving Time

The practice of DST has a long and somewhat complicated history.

• Early Ideas: The concept of adjusting clocks to save daylight dates back to the late 18th century, with proposals by Benjamin Franklin and others. However, these were more conceptual than practical.
• World War I: DST was first widely adopted during World War I to conserve energy by reducing the use of artificial light. Many countries, including the United States, implemented DST during this time.
• Intermittent Use: After the war, DST was inconsistently applied in the United States. There were periods of national DST and periods where individual states and localities could decide whether to observe it.
• Uniform Time Act: The Uniform Time Act of 1966 established a uniform system of DST in the United States, with some exceptions. This act standardized the start and end dates of DST across most of the country.
• Modern Era: The Energy Policy Act of 2005 extended the length of DST in the United States, changing the start and end dates. DST now begins in March and ends in November.

The Impact of Daylight Saving Time

• Sleep Disruption: The most immediate effect of DST is the disruption to sleep patterns. When clocks spring forward, people lose an hour of sleep, which can lead to fatigue and other health effects. Conversely, falling back gives people an extra hour of sleep, but it can still disrupt routines.
• Health Concerns: Studies have linked the transition to and from DST with increased rates of heart attacks, strokes, and other health issues. The disruption to the circadian rhythm can have significant physiological effects.
• Economic Effects: There are debates about the economic benefits of DST. Some studies suggest a positive impact on retail and tourism, while others find no significant effect or even a negative impact.
• Social Implications: DST can affect social activities, transportation schedules, and communication, especially during the transition periods. Coordinating activities across different time zones can also become more complex.

States that Don't Observe DST

Not all states in the U.S. observe DST. The following states and territories do not change their clocks:

• Arizona (excluding the Navajo Nation)
• Hawaii
• American Samoa
• Guam
• Puerto Rico
• The Virgin Islands
