This year's daylight saving time from the first Sunday in October, Sydney, Melbourne and the domestic jet lag will change from the current 2 hours to 3 hours!
Night owls can start at 2 am on Sunday, October 4, to witness this moment. This is a magical moment, all electronic time will automatically jump from 1:59 to 3! Home will not automatically change the clock, you need to manually speed up an hour oh.
Daylight saving starts on 4 Octobe
What is daylight saving time?
Daylight saving time (Daylight Saving Time,DST), also known as "daylight saving time system ", is a man-made local time system to save energy.
Simply put, in the morning and early summer, people can get up early and go to bed early, make full use of light resources, and save electricity for lighting.
Enter daylight saving time, our time will disappear out of thin air 1 hour, for those who work regularly, if still get up as usual, will become less than an hour of sleep!
This year's daylight saving time will end in April, and the lost hour will return, but more and more people are calling for the abolition of daylight saving time. Because, scientists have found that setting the clock fast for an hour has implications for health, road traffic accidents and medical malpractice.
Advantages of daylight saving time
Many retailers are positive about the summer system. American confectionery groups have lobbied the U.S. parliament to extend the summer to November, because Halloween is the most popular season for candy sales, and parents don't want their children to hang out after dark. However, the purpose of this increased evening activity is only for businessmen to make money, but also to increase energy consumption, not to save energy.
Summertime can bring convenience to people with night blindness.
Disadvantages of daylight saving time
1. disrupted people's circadian rhythms
In short, circadian rhythms are biological clocks that determine when certain signals and basic functions are performed. In terms of health, experts say daylight saving time will increase health risks, mainly because it disturbs people's circadian rhythm.

Research by the American Academy of Sleep Medicine (AASM) found that daylight saving time change causes a "phase delay" in circadian rhythms ".
In addition to disrupting people's circadian rhythms, daylight saving time can also lead to "disorder" and lead to other health problems, including high heart rates, lower blood pressure and sleep ability.
Studies show that soon after daylight saving time begins, all heart-related problems, such as heart attacks, strokes and other heart problems, will follow.
Furthermore, researchers believe that daylight saving time can cause people to reduce sleep time, release stress hormones (stress hormones), and increase the probability of inflammation.
2. mood changes
Daylight saving time has a huge impact on health, which also affects a person's mood and even causes suicide in extreme cases.
3. traffic accidents are increasing
Traffic accidents tend to increase in the first few days of daylight saving time, according to the American Academy of Sleep Medicine.
4. Increased number of medical incidents
In addition, the study found that a week before and after daylight saving time, human error caused by medical accidents increased trend. It is reported that after entering the summer, man-related accidents accounted for 18, far more than the usual 5.
I can't 5.change the sun schedule
On agriculture, grain growth and livestock grazing do not occur automatically according to the clock change. milking time, grain is harvested after dew evaporates, and these schedules are not change. by daylight saving time
6. disrupt the operation of the machine
When daylight saving time begins, it "disappears" for a few hours, so if you don't pay attention to the timing of the start and stop machine, it will lead to the start or stop phenomenon before the actual elapsed time has reached the preset time. For example: the instrument that must operate 5 hours, encounter the daylight saving time that dials 2 hours, may operate 3 hours to stop automatically; and the instrument that originally starts automatically after 5 hours, encounter the daylight saving time that dials 2 hours, may start 2 hours ahead of time. Similarly, at the end of daylight saving time, some time will appear twice on the same day, which can easily constitute chaos. Therefore, at the beginning or end of daylight saving time, if not paid attention to, it will cause problems in the fields of transportation, production, medical treatment, scientific research, meeting arrangement and so on.
7. impact work and learning efficiency
Daylight saving time has little effect on low latitudes. In particular, these places are hot and humid in summer, sultry at night, and early morning is a good time to sleep. Hot summer, people generally sleep late, summer time will lead to shorter sleep time, resulting in people to go to school listless, affect work efficiency, but cause greater waste.
Daylight saving change does do more harm than good, such as health problems, mood changes, road traffic accidents and medical malpractice.
A number of experts this year called for government to cancel daylight saving time because of concerns about its negative impact. The diabetes professor at Monash University Paul Zimmet worried that health risks associated with daylight saving time may increase during the epidemic and that health authorities need to consider the negative effects of daylight saving time.
But the governor of Virginia Daniel Andrews responded :" There is no possibility of canceling daylight saving time! An additional hour of sunshine is expected to make summer different, and daylight saving time will be a feature of summer.
In fact, Australians have been discussing whether to abolish daylight saving time. Daylight saving time is still available in Xinzhou, Virginia, the Capital Territory, South Australia and Ta' a, while Western Australia, Queensland, the Northern Territory and Yucatán do not.
Daylight Saving Time Australia Time Zone becomes 5
If daylight saving time is not used, Australia's time zone will be divided into three, once entering daylight saving time, the time zone will increase to five!

By October 4, when you enter daylight saving time, you will find:
- Sydney | Melbourne | Canberra | Hobart :9am
- Adelaide 8:30 am
- Brisbane 8:00 am
- Darwin 7:30 am
- 6 a.m. Perth
There are a total of 5 time zones, summer time in Australia to play a circle, to pour 5 time difference.
Why are daylight saving time still being used in several parts of Xinzhou, Victoria, Capital Region, South Australia and Taz? Actually, the origin of daylight saving time and environmental protection are not relationship, more like personal hobbies dominate human behavior.
New Zealand entomologist George Hudson first introduced the concept of modern daylight saving time. He thinks getting up early is good for him to collect insect samples. So in 1895, he proposed seasonal time to the Wellington philosophy Society.
But daylight saving time was implemented because the German and Austro-Hungarian empires supplied the war to save coal during World War I. After the war, many countries abolished summertime, which was once again widely used until the energy crises in America and Europe in the 1970s.
According to reports, research data show that daylight saving time contributes less than 1% to energy conservation. Energy not only does not save much, but also creates a lot of trouble and trouble. Nowadays, many countries have cancelled daylight saving time.
A poll was conducted on whether daylight saving time was cancelled or not. The results show that 65% of Australians still choose to continue to use daylight saving time!
Friends, do you support daylight saving time? What do you think of it?
