What's the schedule in Beijing?

1. Winter schedule -8: 00- 12: 00,? 14: 00- 18: 00 (or: 13: 00- 17: 00)

2. Work and rest time in summer -7: 00- 1 1: 00, 14: 00- 18: 00.

3.1986 In April, China adopted daylight saving time.

The specific method is: from 2: 00 am (Beijing time) on the first Sunday in mid-April every year, set the clock forward 1 hour, that is, set the hands of the watch to 2: 00 to 3: 00 to start daylight saving time;

By 2 am on the first Sunday in mid-September (Beijing daylight saving time), put the clock back one hour, that is, set the pointer from 2 o'clock to 1, and daylight saving time will be over.

During the six years from 1986 to 199 1, except that 1986 is the first year of daylight saving time, all other years are implemented according to the specified time period.

Extended data:

In China, every year on the first Sunday in mid-September at 2: 00 am (Beijing daylight saving time), when the clock is set back to standard, it is set back by one hour, which is winter time;

Starting from 2: 00 a.m. (Beijing time) on the first Sunday in mid-April, set the clock back to the standard time and advance it by one hour, that is, daylight saving time; Generally, May 1 day and 10/month 1 day are the dividing lines.

China has implemented daylight saving time since 1986. During daylight saving time, Beijing time was changed to Beijing daylight saving time, ending at 1992.

It was abandoned because China people's national knowledge about seasons was relatively low at that time, so people would not calculate this daylight saving time. Although there was only a time difference of half an hour, many people were not used to it, which led to missing the train and plane, so it was later cancelled.

In fact, China should implement some corresponding systems, and there will be no problem with the time difference between north and south, mainly because there is a problem with the east-west span, because the time zone means that no matter how far north and south are, it is the same time, and east and west only need to cross an area for one hour.

For example, when the morning news was broadcast in China and Beijing, it was still evening in Xinjiang, and when the news was broadcast in Xinjiang, Beijing had already started a day's work.

But in any case, it is more convenient at one point, and there is no need to calculate a few points when you get to a place. As for energy saving, I really don't know. I haven't heard of it. As for adoption, it seems that all countries except China are adopting with jet lag.

France first followed the example of Britain in 19 16 and abolished it during World War II. After the first oil crisis, in order to save energy, France resumed winter time at 1976. Paris Stock Exchange: Beijing time 16:00-00:30, daylight saving time 15:00-23:30.

The French side believes that the implementation of dual-time system in summer and winter in France can reduce the demand for lighting electricity by 4% every year.

The European Union adopted the summer and winter dual-time system in 1986, but there are some differences among member states.

At present, most member countries take Berlin meridian as the benchmark, and Greenwich Mean Time+1in winter; Summer, GMT +2.

Britain, Ireland and Portugal are based on Greenwich Meridian, Winter and Greenwich Mean Time. In summer, GMT+1

Greece and Finland are based on the meridian of Ankara, Turkey, with Greenwich Mean Time+2 in winter; In summer, GMT +3.

At present, countries adopting winter time include Mexico, Canada, the United States, Brazil, Syria, Israel, Egypt and Jordan.

It starts on the last Sunday of March and ends on the last Sunday of 10.
