Daylight Saving Time – DST – Summer Time

Daylight saving time (DST) advances the clock one hour ahead of the standard time of daylight saving time, and then sets it in the autumn to make more effective use of natural daylight saving time.

"Spring advancement, retreat" is one way to keep your watch set. Set the clock at the beginning of DST (= 1 hour lost), 1 hour in spring, 1 hour (1 hour recovery) at the end of autumn.

Many countries in the northern hemisphere (north of the equator) use summer time in summer, but not all. Daylight saving time usually begins from March to April, the country will return to standard time from September to November.

In the Southern Hemisphere (south of the Equator), the participating countries usually start the summer season from September to November and end the summer time from March to April.

American inventor and politician Benjamin Franklin first proposed the concept of daylight saving time in 1784, but modern daylight saving time was first proposed in 1895. At that time, New Zealand's entomologist George Vernon Hudson proposed a two-hour summer recommendation. Forward

Less than 40% of the world uses daylight saving time. Some countries use it to better utilize the natural light of the night. The difference in light is most pronounced at a certain distance from the Earth's equator.

Several studies show that DST can reduce traffic accidents and injuries by providing more sunlight when more people use the road. Other studies say people's health may be affected by changes in DST

DST is also used to reduce the amount of energy required for nighttime artificial lighting. However, many studies are against energy conservation in DST, but some studies show positive results, but that is not the case.

However, on Lord Howe Island in Australia, the time from LHST (UTC + 10: 30) to LHDT (UTC + 11) is only 30 minutes during summer time.

Throughout history, there were some changes such as semi-adjustment (30 minutes) and double adjustment (2 hours). Also used for twenty and forty minutes adjustment

Daylight saving time (DST, also known as daylight saving time) is a habit of advancing watches to give more daylight time and less morning. Normally, you will advance the clock for 1 hour in spring and adjust the clock behind in the fall. The use of DST varies from country to country. Changing from standard time to daylight saving time is fine. It is because it has advanced one hour. Normally, the clock jumps from 02:00 of standard time to 03:00 of daylight saving time. The time on that day is 23 hours. In this case, there is no data from 02:00 to 03:00 in the morning from that time, that day does not exist.

Daylight saving time (daylight saving time), daylight saving time (the United States), daylight saving time (UK and others) is the custom of lengthening nighttime daylight saving time by sacrificing normal sunrise time by advancing the clock during the summer. Normally, in areas where daylight saving time is used, adjust the clock one hour before the beginning of spring and return to the standard time of autumn. In fact, DST shortens spring sleeping time and reduces fall sleep time by one hour.

Abstract: "We are using daylight saving time (DST) using policy discontinuity and DST extension in 2007 as an extrinsic influence on daylight saving time.Theft is reduced by 7% As we expected, it turned out to be the most effective for the change of the daytime, saving social costs by $ 59 million each year.
