US President-elect Donald Trump has promised to end Daylight Saving Time (DST), calling it “inconvenient and costly to the country”.
Daylight Saving Time
- Daylight Saving Time (DST) is a process in which the clock is moved forward by one hour in summer and backward by one hour in autumn.
- Purpose: Its main purpose is to make better use of natural daylight so that there is more light in the evening and the need for artificial lighting is reduced.
- Methodology: Countries that follow DST move the clock forward by one hour in summer and back in autumn.
Status in India
- India does not follow DST.
- In tropical countries like India, there is not much change in the hours of the day, so there is no need for DST.
- Global practice: DST is more prevalent in countries located away from the equator, where there is a large variation in day and night hours depending on the season.
First use
- Daylight Saving Time (DST) was adopted on July 1, 1908, in Port Arthur (Ontario), Canada.
- In April 1916, during World War I, Germany and Austria implemented DST to reduce the use of artificial light.
Significance and Challenges
Significance
Energy Saving
- The purpose of DST is to save energy. The clock is set forward one hour in the spring and back one hour in the fall, to take advantage of longer daylight hours.
- It is expected that people will use more natural light and reduce the consumption of artificial light.
- Economic benefits: More daylight hours allow people to spend time outdoors, which can benefit the local economy, such as more customers for stores and restaurants.
- Improved public safety: More daylight can reduce the likelihood of accidents and crime in the evening.
Challenges
- Sleep disruption: DST changes people’s sleep patterns and body clocks (circadian rhythm), which can have negative health effects, such as fatigue, mental stress, and other problems.
- Increased energy consumption: Some studies suggest that DST results in little or no energy savings. In some areas, energy consumption may even increase.
- Inconsistencies in time zones: DST is not applied everywhere, which can lead to confusion across different time zones. This can cause problems with business, travel, and communication.
- Other negative impacts: Workplace injuries may increase after DST, leading to lost work days. As a result, stock market performance may also be affected in some regions.
