As winter fades away, the much-awaited spring season marks its arrival with a significant change – resetting the clock. Every year, the clock springs forward by an hour, leading to one hour less of sleep but an extra hour of sunlight in the evenings. The practice of changing clocks twice a year is known as Daylight Saving Time, and it has been observed by many countries for over a century. In this article, we will discuss the history, reasons, and schedule of the Daylight Saving Time.
What is Daylight Saving Time?
Daylight Saving Time (DST) is the practice of setting the clock forward by one hour during summers and setting it back to standard time during winters. During the DST, the evenings are lighter, and mornings are darker. The practice was first proposed and implemented by Benjamin Franklin in the late 18th century to save candles used for lighting. However, it was only in 1908 that the DST became official and widely accepted.
Reasons for Daylight Saving Time
The primary purpose of DST is to save energy and utilize the sunlight for an extra hour. During the war, several countries adopted the DST practice to save coal and oil used for generating electricity. Additionally, the DST provides a more extended time in the evenings for outdoor activities, thus boosting tourism and retail sales.
When does Daylight Saving Time begin and end?
The DST change dates and schedules vary from country to country. In countries such as the United States, Canada, and several European countries, the DST begins on the second Sunday of March and ends on the first Sunday of November annually. In countries such as Australia, the DST period changes from state to state. On the other hand, some countries that follow a tropical climate, such as Singapore and Malaysia, do not observe any DST.
How to remember when to change clocks?
Changing two times a year can cause confusion, especially when traveling around the world. However, using a simple mnemonic can help remember when to change the clock. The term “spring forward, fall back” positions the clock ahead one hour in spring, and back one hour in the fall or autumn.
Pros and Cons of Daylight Saving Time
Advantages of Daylight Saving Time
- Energy-saving: DST helps save energy and reduces the need for artificial lighting.
- Less traffic accidents: With more light in the evenings, traffic accidents and fatalities are reduced.
- Boosts tourism: Longer evenings encourage more outdoor activities and tourist attractions, thus boosting local economies.
Disadvantages of Daylight Saving Time
- Health concerns: Lack of sleep after the clock change can cause drowsiness, distraction, and accidents.
- Work productivity: Employees often experience a lack of sleep and tend to be less productive, which can cause a loss of revenue.
- Higher energy consumption: Although DST helps reduce artificial lighting, it leads to higher consumption of air conditioning and other appliances during summer afternoons.
