Daylight saving time (DST) is the practice of advancing clocks during summer months so that evenings have more daylight and mornings have less. The exact start and end dates of DST vary by country, but it is typically observed from March or April to October or November. In the United States, DST begins on the second Sunday of March and ends on the first Sunday of November.
DST has a number of benefits, including reducing energy consumption, decreasing traffic accidents, and improving public safety. A study by the U.S. Department of Energy found that DST saves about 1% of the country’s electricity usage. This is because people are more likely to use natural light in the evenings when DST is in effect, which reduces the need for artificial lighting. DST can also reduce traffic accidents by making it easier for drivers to see at night. A study by the National Highway Traffic Safety Administration found that DST reduces fatal crashes by about 1%. Finally, DST can improve public safety by making it more difficult for criminals to operate under the cover of darkness. A study by the University of California, Berkeley found that DST reduces crime rates by about 7%.
The history of DST dates back to the late 18th century. Benjamin Franklin first proposed the idea of DST in 1784, but it was not until 1918 that DST was first implemented on a widespread basis. During World War I, DST was used as a way to conserve energy. After the war, DST continued to be used in many countries, although the exact start and end dates varied. In the United States, DST was first standardized in 1966.
1. Start date
The start date of daylight saving time (DST) is important because it marks the day when clocks are moved forward one hour. This change gives us more daylight in the evenings and less daylight in the mornings. In the United States, DST begins on the second Sunday of March and ends on the first Sunday of November. So, the start date of DST in 2025 is March 9, 2025.
Knowing the start date of DST is important for a number of reasons. First, it helps us to plan our schedules. For example, if we know that DST begins on March 9, 2025, we can make sure to adjust our clocks accordingly. Second, knowing the start date of DST can help us to avoid confusion. For example, if we are traveling to a different time zone, we need to know whether or not DST is being observed in that time zone. Finally, knowing the start date of DST can help us to make the most of the extra daylight. For example, we can plan outdoor activities or spend more time with our families and friends.
The start date of DST is a relatively minor event, but it can have a significant impact on our lives. By understanding the importance of the start date of DST, we can make sure that we are prepared for the change and that we can take advantage of the extra daylight.

The end date of daylight saving time (DST) is important because it marks the day when clocks are moved back one hour. This change gives us less daylight in the evenings and more daylight in the mornings. In the United States, DST begins on the second Sunday of March and ends on the first Sunday of November. So, the end date of DST in 2025 is November 2, 2025.
- Planning and Scheduling: Knowing the end date of DST is important for planning and scheduling purposes. For example, if we know that DST ends on November 2, 2025, we can make sure to adjust our clocks accordingly. This will help us to avoid being late for appointments or missing important events.
- Energy Consumption: The end date of DST can also have an impact on energy consumption. Studies have shown that DST can lead to a decrease in energy consumption, as people are more likely to use natural light in the evenings when DST is in effect. This can lead to lower energy bills and a reduced carbon footprint.
- Health and Well-being: The end date of DST can also have an impact on our health and well-being. Some studies have shown that DST can lead to an increase in the risk of heart attacks and strokes. This is because DST can disrupt our sleep patterns and make it more difficult for our bodies to adjust to the change in time.
- Travel and Transportation: The end date of DST can also have an impact on travel and transportation. For example, if we are traveling to a different time zone, we need to know whether or not DST is being observed in that time zone. This will help us to avoid confusion and make sure that we arrive at our destination on time.
The end date of DST is a relatively minor event, but it can have a significant impact on our lives. By understanding the importance of the end date of DST, we can make sure that we are prepared for the change and that we can take advantage of the extra daylight.
