Donald Trump has endorsed ending the twice a year clock-bending Daylight Savings Time ritual, echoing many Americans' frustrations with Saturday night's loss of an hour of sleep that they won't get back until November.

'Making Daylight Saving Time permanent is O.K. with me!' the president tweeted Monday morning.

DST changes the clock-time of sunrise and sunset, an idea that dates back to ancient Rome but had its modern rebirth thanks to New Zealand entomologist George Vernon Hudson.

President Donald Trump said Monday on Twitter that he would endorse ending the practice of Daylight Savings Time, permanently leaving America's clocks where they are now

Hudson proposed the idea in 1895, telling fellow scientists that two extra hours of sunlight would give him more time in the evening to collect bugs after his day-shift at the post office was over.

He was mocked for decades, but eventually a one-hour shift took hold in New Zealand, in 1923. By then most of Europe had shifted to save fuel during World War I.

President Franklin Roosevelt instituted the plan, then called 'War Time,' in February 1942 – a few months after the U.S. entered World War II. He ended the practice four weeks after Japan's surrender in September 1945.

Today 48 of the 50 U.S. states observe DST, all but Arizona and Hawaii. Some Navajo reservations inside Arizona's borders buck that trend, however, joining the rest of the country.

Most of America – 48 states plus a small area of Indian tribal land inside Arizona – participate in the 'spring forward, fall back' ritual; Hawaii sits it ou, along with the non-Indian-reservation majority of Arizona

The American territories of American Samoa, Guam, Puerto Rico, the Northern Mariana Islands and the U.S. Virgin Islands also keep their clocks constant year-round.

Medical studies have found having an earlier sunrise time for half of the year motivates most people to be more active in the morning.

But the earlier darkness in the evening can deepen clinical edpression for people who suffer from Seasonal Affective Disorder. It can also disrupt the circadian rhythms that tell the human body when to produce melatonin, a hormone that prepares the brain for sleep.

And technological advancements have confounded the original purpose of saving on energy costs, thanks to increased use of air conditioning in summertime.

An Englishman named William Willett is often wrongly credited with first proposing Daylight Savings Time.

Overnight between Saturday and Sunday, nearly all Americans lost an hour of sleep when 2:00 a.m. instantly became 3:00 a.m.

Willett's idea, outlined in a 1908 book titled 'The Waste of Daylight,' was to shift Britain's timepieces by just 20 minutes. Parliament, at the time, was not impressed.

DST will be in the news next year thanks to Tokyo Olympics organizers who have proposed a nationside one-hour time shift to help athletes and spectators avoid the kind of scorching heat that killed at least 120 people in Japan.

The International Olympic Committee is backing the one-time proposal.

Three-quarters of Japan's private sector businesses oppose the idea, according to a Reuters poll, saying it would be too much trouble to adjust the nation's computer systems.
