Daylight Saving Time

 


On Sunday, November 3, 2024 (the first Sunday in November), at 2:00 AM, clocks were turned backward one hour to 1:00 AM. This was officially the end of Daylight Saving Time (DST) in the US, time to “Fall Back.”


Humans may or may not appreciate the change in time. My dogs, however, think I am the worst person on earth for “delaying” dinner time. I am convinced they have an internal alarm clock. One pup is whining at my side while I write this blog post.


DST was first observed in 1918 to conserve energy during WWI and WWII, to permit more cost-effective war-time production, and to mitigate blackouts. In fact, at times, it was called “War Time.”


From 1945 to 1966, there were no uniform DST rules, which was chaotic for broadcasting and transport. The Uniform Time Act of 1966 aligned switch dates across the US.


There were two periods after the 1973 Oil Embargo when the DST period was extended to try to save energy: ten months in 1974 and eight months in 1975. Over the next 11 years, the DST schedule was revised several times.


From 1987 to 2006, the time changes occurred on the first Sunday in April and the last Sunday in October, lasting seven months each year. The current time change schedule was adopted in 2007 to follow the Energy Policy Act of 2005, which extended DST by several weeks.


Per section 110 of this act, DST is governed by the US Department of Transportation (DOT). States have the right to choose not to observe DST. Hawaii, all of Arizona (except for the Navajo Nation region), and the US Dependencies (Territories) do not observe DST.


Worldwide, there is a greater variance in the use of DST. Vast areas that once utilized DST no longer do.



Are you for or against DST? For now, biannual time change is the law of the land, and DST will resume on the second Sunday in March, March 9, 2025. Once again, the clocks will be turned forward from 02:00 AM to 03:00 AM. Time to “Spring Forward.”

Earth Rotation Day

Image
Today, we think about the Earth’s movement:  rotation  means to turn, and  revolution  to go around. It wasn't always evident that these motions occurred. Ptolemy postulated that the Earth was the center of the Universe and that the Sun revolved around our planet. Copernicus performed experiments that showed the opposite was true and published his results in 1543, months before his death. The printer added disclosures regarding the validity of the statements and suggested the information only aided astronomers. His book was banned by the Catholic church as heresy in 1616. In 1632, Galileo agreed with the Heliocentric Model aided by the use of his telescope. He, too, was accused of heresy and placed under house arrest for the remainder of his life. It was not until 1758 that the Catholic Church decided it was not heretical to say the Earth rotates around the Sun. Leon Foucault proved the theory of rotation with his famous pendulum experiment.

The Grandest Fir

Following our family tradition, we traveled to a  local Christmas tree farm  the day after Thanksgiving. We arrived shortly after opening time and were able to promptly board the trolley to ride up the hill to the area of the farm being utilized for harvest this season. This particular business is an excellent caretaker of their trees, allowing harvest from only one section at a time and promptly replanting in the spring. Frosty’s system is finely organized: you choose a tree, place your tree pole green end up, and a tree cutter is at your side within minutes. The rest of the process is effortless: a ride back downhill, this time on a tractor-drawn trailer with hay bale seats, to the main building to pay, then well-marked signage to the pickup area. Meanwhile, the tree was bagged up on the hillside, delivered car-side, and secured to the roof. Unfortunately, the tree farm staff did not accompany us home to assist with unloading, carrying up a flight of entry stairs, across the great ro

January 18th: National Thesaurus Day

Image
The thesaurus, a book that serves as a cross-reference for synonyms, and serves as a guide to effective and precise use of language, is a necessary tool of every writer and even some readers. Dr. Mark Peter Roget (1779–1869) was a British natural theologian, physician, and lexicographer. He suffered from depression his entire life: beginning at the age of eight, his coping mechanism was obsessive list-making. He wrote the first draft of the eponymous English-language thesaurus in 1805, two years prior to Webster beginning the undertaking of his own dictionary. For 47 years he kept it a secret, and finally published it in 1852 at the age of 73, under the title  Thesaurus of English Words and Phrases Classified and Arranged so as to Facilitate the Expression of Ideas and to Assist in Literary Composition . This document is archived in the Karpeles Manuscript Library Museum. Roget’s Thesaurus has been in continuous print. The original manuscript included 15,000 words; the Eighth Edition i
