The time is near to roll that clock back one hour. Just in case some of you didn’t notice, it’s getting darker sooner. Daylight saving will occur on November 4, 2018. Now you can snooze for one-hour longer until the next daylight saving. Most areas of the United States observe daylight saving time, the exceptions being Arizona (except for the Navajo, who do observe daylight saving time on tribal lands), Hawaii, and the overseas territories of American Samoa, Guam, the Northern, Mariana Island. Puerto Rico and the United States Virgin Islands. Europe, and some areas in the Middle East, (DST), while most areas of Africa and Asia do not. In South America, most countries in the north of the continent near the equator do not observe DST, while Paraguay and southern parts of Brazil do.If you live near the equator, day and night are nearly the same length (12 hours). But elsewhere on Earth, there is much more daylight in the summer than in the winter. The closer you live to the North or South Pole, the longer the period of daylight in the summer. Thus, Daylight Saving Time (Summer Time) is usually not helpful in the tropics, and countries near the equator generally do not change their clocks. In the winter, the afternoon Daylight Saving Time advantage is offset for many people and businesses by the morning’s need for more lighting. In spring and fall, the advantage is generally less than one hour. So, the rationale was that Daylight Saving Time saves energy for lighting in all seasons of the year, but it saves least during the four darkest months of winter (November, December, January, and February), when the afternoon advantage is offset by the need for lighting because of late sunrises. So on Nov 4, 2081 make sure you set your clock’s back one hour.
