Daylight Saving Time, which is popularly referred by its acronym DST, is a practice wherein clocks in some nations are changed during summer months to make better use of the daylight. The practice involves advancing clocks during summer months to extend an hour of daylight. In countries where daylight saving time is followed, clocks are set forward by an hour at the start of spring. In autumn, clock ‘turned back,’ or adjusted to the standard time. But every country that follows DST has its own dates for when it adjusts their clock.

Though Benjamin Franklin is erroneously considered as inventing daylight-saving time, it was George Hudson, a New Zealander entomologist, who actually proposed the modern DST. He proposed a two-hour daylight-saving shift in a paper that he presented to the Wellington Philosophical Society in 1895. Meanwhile, there are many publications that credit the daylight-saving time to William Willett, an English builder. While out on a pre-breakfast ride in 1905, he observed that many people in London slept through a major part of the summer day. Thus, he published a proposal two years later where he stressed on advancing the clock during summer months. However, his idea never became a reality during his lifetime.

In 1916, at the height of World War I, Germany became the first nation to adopt daylight saving time. With war raging, it was essential to conserve energy and Germany found DST a viable solution. Sometime later, the United Kingdom also embraced DST. Russia adopted DST in 1917, while the United States followed in 1918. Though some countries did away with DST in the years following the end of WW I, but was again observed during WW II. It was during the 1970s energy crisis that hit many countries badly that DST became a common practice in North America and Europe.

Today, there are some nations, both in the southern and northern hemisphere, that are following daylight saving time, while others do not use it. Meanwhile, there are quite a few that have used DST at some point in time.

There are a couple of nations in the Southern Hemisphere that use daylight saving time. These nations are; Fiji, Namibia, New Zealand, Paraguay, Samoa, and Tonga. DST is not observed across the entire nation in Australia, Brazil and Chile. In Australia, New South Wales, Victoria, Tasmania, Australian Capital Territory, Jervis Bay Territory, South Australia and Lord Howe Island observe DST. Similarly, in Brazil regions where DST is used are Rio de Janeiro, Santa Catarina, Mato Grosso, Federal District Brasilia, São Paulo, Paraná, Goiás, Rio Grande do Sul, Mato Grosso do Sul, Espírito Santo, and Minas Gerais. Chile uses DST, except for the Magallanes region, which last used DST in December, 2016.

Meanwhile, the list of nations and territories in the Northern Hemisphere using DST is quite long. A few nations and territories include Austria, Belgium, Bermuda, Cuba, Denmark, Greenland, Iran, Morocco, Spain, the United Kingdom, and some other nations. Most of the United States uses DST barring Hawaii and Arizona (except the Navajo Nation Community). In Canada, DST is not observed in some regions in Quebec, major part of Saskatchewan, and a couple of areas in British Columbia and Nunavut (Southampton Island). In Greenland, Danmarkshavn and Pituffik don’t follow DST, while the rest of it does.

Afghanistan, Bahrain, Cambodia, Equatorial Guinea, Ethiopia, Kenya, Maldives, North Korea, Qatar, Swaziland, the United Arab Emirates, and some others, do not observer DST. However, there are quite a few countries and territories which at one point of time did observe daylight saving time. Some of these are India, Japan, Hong Kong, Armenia, China, Colombia, Egypt, Malaysia, and a couple of others.

Despite the fact that DST was introduced for the common good of the people, there are both proponents and opponents of the system. Those in favor of DST lay stress on the fact that it is good for health as it promotes outdoor leisure activity, is good for businesses and reduces accidents, among others. However, those against DST consider it to be a nuisance as they have to adjust to a new sleep schedule. They also state that adjusting to the time change also affects work productivity. Other than this, more gasoline is used as people may visit their friends in the evenings or do some other work.
