   Extractions: Spring forward...Fall back.... It's ingrained in our consciousness almost as much as the A-B-Cs or our spelling reminder of "i before e...." And it's a regular event, though perhaps a bit less regular than the swallows coming back to Capistrano. Yet in those four words is a whole collection of trivia, facts and common sense about Daylight Saving Time. Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April ( see chart below ). Time reverts to standard time at 2 a.m. on the last Sunday of October. Daylight Saving Time for the U.S. and its territories is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Eastern Time Zone portion of the State of Indiana, and by most of Arizona (with the exception of the Navajo Indian Reservation in Arizona). California has not yet received federal "approval" to move to a "year-round" Daylight Saving Time in 2001-2002. (

   Extractions: Robert Garland investigates the ancient origins of the calendar and time-keeping systems of the Western world. Our present system of timekeeping provides us with a year of fixed and unalterable length which requires only the intercalation of a single (leap) day every four years. We seem to hold the passage of time so securely within the palms of our hands that we can almost hear its quiet heartbeat. Our present calendar has become so accurate that it will take 44,000 years before it falls out of step with the sun by so much as a single day. Pre-industrial societies base their estimate of the year's length on a variety of repetitive occurrences in the natural world. These occurrences include changes in vegetative growth, the phases of the moon, the solstices, and the movement of the stars. Thus the Greek poet Hesiod, who lived in the seventh century BC, advised farmers in Works and Days to begin the harvest when the constellation known as the Pleiades was rising and to begin ploughing when it was setting, but to sharpen their agricultural implements when snails began climbing up plants.

4. The History Of Timekeeping
   The history of time keeping. In respect to human history, time keeping is a relatively recent desire – probably 5000 to 6000 years old.

   Extractions: It was most likely initiated in the Middle East and North Africa. A clock is defined as a device that consists of two qualities: A regular, constant or repetitive process or action to mark off equal increments of time . Early examples of such processes included movement of the sun across the sky, candles marked in increments, oil lamps with marked reservoirs, sand glasses ("hourglasses"), and in the Orient, small stone or metal mazes filled with incense that would burn at a certain pace.

   Extractions: Bibliography N ot until somewhat recently (that is, in terms of human history) did people find a need for knowing the time of day. As best we know, 5000 to 6000 years ago great civilizations in the Middle East and North Africa began to make clocks to augment their calendars. With their attendant bureaucracies, formal religions, and other burgeoning societal activities, these cultures apparently found a need to organize their time more efficiently. T he Sumerian culture was lost without passing on its knowledge, but the Egyptians were apparently the next to formally divide their day into parts something like our hours. Obelisks (slender, tapering, four-sided monuments) were built as early as 3500 BCE. Their moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon. Obelisks also showed the year's longest and shortest days when the shadow at noon was the shortest or longest of the year. Later, additional markers around the base of the monument would indicate further subdivisions of time. Another Egyptian shadow clock or sundial, possibly the first portable timepiece, came into use around 1500 BCE. This device divided a sunlit day into 10 parts plus two "twilight hours" in the morning and evening. When the long stem with 5 variably spaced marks was oriented east and west in the morning, an elevated crossbar on the east end cast a moving shadow over the marks. At noon, the device was turned in the opposite direction to measure the afternoon "hours."

    Extractions: Keeping Time: The History and Theory of Preservation in America by William J. Murtagh This popular classic on preservation in America returns to print in a revised edition as part of the distinguished Preservation Press series. Written by the first Keeper of the National Register for Historic Places, it remains the quintessential textbook of graduate and college-level courses in Historic Preservation and Architectural History. Features 75 black-and-white photographs that underline relevant issues and events in American community preservation, plus three reference appendices of legal, historical and practice information. William Murtagh, the first Keeper of the National Register of Historic Places, presents an effective portrait of the preservation movement by looking into the values underlying the efforts to safeguard America's architectural heritage, including the development of legislation and court action. A section on the National Trust for Historic Preservation explains how this private, non-profit organization created in the 1940s has expanded its services and goals parallel with changes in the national preservation movement.

Introduction Initial Evidence of Time The Presocratics Changing Attitudes Towards Time ... Bibliography Look at the comments on this paper. Whether for agricultural, legal, or religious purposes, the ability to measure time was of the utmost importance in ancient Greece. Homer and Hesiod both suggest that men recognized some connection between the sun, stars, moon, earth, and time, but were unable to observe very effectively the cosmos for purposes of chronology. Only with the advancement of astronomy, beginning with Thales in the early sixth century BC, could the Greeks begin to utilize the heavens for designing accurate calendars and sundials. Eventually, Plato, in is Timaeus , would declare, "The sun, moon, and... planets were made for defining and preserving the numbers of time. "

    Extractions: There was no such thing as a wristwatch in those days, although Queen Elizabeth I is said to have at times worn a small watch as a bracelet. In fact, the wristwatch didn't really come into use until the tile of the First World War around 1916. Watches before then were carried in a pocket and often attached to a chain to prevent theft. of Bogoff.com During the 1600s, watches were very expensive and only the very wealthy could afford them. Clocks were also very expensive. In fact, neither watches nor clocks were very good timekeepers anyway. It wasn't until the invention of the pendulum by Galileo in the 1630s that a clock might be accurate to within minutes. Before that, a clock might gain fifteen minutes a day and lose half an hour the next. Because they were so erratic, there were no minute hands, much less second hands. As today, their dials were numbered I to XII, but obviously there were no minute markings. The space between each of the hour markings was marked in quarter hours, often with a

Yet only humans "keep time" and are concerned about being "on time." How have the standards for measuring time changed throughout recorded history? Since ancient times, humans have attempted to organize the cycle of the seasons. Without even understanding that Earth revolves around the Sun, they built calendars based on a solar year. Over 5,000 years ago civilizations had also started the quest for accurate ways to tell the time of day as Earth rotates on its axis. They used observations of the Sun and other heavenly bodies to indicate times like noon. But the challenge facing developing cultures was how to divide the day into regular units that could be synchronized, even in cloudy weather. The ancient Egyptians made several contributions to horology, the science of measuring time. Around 1500 B.C., they developed a sundial, onto which they divided the daylight hours into 10 equal parts. They also defined two hours as "twilight hours," one in the morning and one in the evening. Historians believe that the Egyptians used an early astronomical tool called a
