At 3 AM on Sunday, October 28, the clock returns 1 hour and indicates the end of daylight saving time (or daylight saving time) and the start of standard (or winter) time. This adds sleep time and saves a certain amount of energy - theoretically. In fact, there are lots of critics on twice a year change in age, and the movements within the EU will soon abolish it. Our idea is to adapt our body to natural light and save energy, but I think a lot of people actually had a significant savings. Research conducted by the European Commission has shown that saving marginal costs of 0.5% to 2.5% power consumption. Yes, when I go to work in the morning it will be lighter, but when I go home I get dark. In addition to this, human health is also affected as many people feel more tired and more difficult to concentrate on the day after the change of time.

Daylight saving time is to move the watch one hour ahead of spring and return the watch for one hour in the fall. Daylight saving time occurs in most countries of the world, but at different times of the year. Summer time supporters believe that not only can you add more daylight hours to the standard day, but also energy can be saved as people do not have to use as much electricity as possible during the day. The opposite argues that this is no longer the case. Because the use of heating and cooling is very different from when daylight saving time first started, because it actually hurts business like agriculture due to the dark in the morning of summer time.
