Time is the one thing that is shared by all of humanity, irrespective of wealth, health, race or credo; and one of the things that makes us individual is how we choose to spend it. It is one of the commodities over which we have most control, yet it is the asset we value the least. Isn't it time we took control over how we spend it, while we still can? Time will reward readers of lifestyle quests who seek a better, richer, slower, more fulfilling way of life. For anyone who has ever pondered the paradoxes of time and who is interested in looking at their world from a fresh perspective. Whether you want the encouragement to take time out on a life-scale or simply adjust your life to accommodate a timetable that suits you, this book will have plenty of inspiration, suggestions and tips to help you get the most out of your time.

An invaluable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists, astronomers, and other calendar enthusiasts, The Ultimate Edition updates and expands the previous edition to achieve more accurate results and present new calendar variants. The book now includes coverage of Unix dates, Italian time, the Akan, Icelandic, Saudi Arabian Umm al-Qura, and Babylonian calendars. There are also expanded treatments of the observational Islamic and Hebrew calendars and brief discussions of the Samaritan and Nepalese calendars. Several of the astronomical functions have been rewritten to produce more accurate results and to include calculations of moonrise and moonset. The authors frame the calendars of the world in a completely algorithmic form, allowing easy conversion among these calendars and the determination of secular and religious holidays. LISP code for all the algorithms is available in machine-readable form.

What happens when the country's greatest logician meets the century's greatest physicist? In the case of Kurt Godel and Albert Einstein the result in Godel's revolutioinary new model of the cosmos. In the 'Godel Universe' the philosophical fantasy of time travel becomes a scientific reality. For Godel, however, the reality of time travel signals the unreality of time. If Godel is right, the real meaning of the Einstein revolution had remained, for half a century, a secret. Now, half-century after Godel met Einstein, the real meaning of time travel in the Godel universe can be revealed.

The prophet Muhammad and the early Islamic community radically redefined the concept of time that they had inherited from earlier religions' beliefs and practices. This new temporal system, based on a lunar calendar and era, was complex and required sophistication and accuracy. From the ninth to the sixteenth centuries, it was the Muslim astronomers of the Ottoman, Safavid and Mughal empires who were responsible for the major advances in mathematics, astronomy and astrology. This fascinating study compares the Islamic concept of time, and its historical and cultural significance, across these three great empires. Each empire, while mindful of earlier models, created a new temporal system, fashioning a new solar calendar and era and a new round of rituals and ceremonies from the cultural resources at hand. This book contributes to our understanding of the Muslim temporal system and our appreciation of the influence of Islamic science on the Western world.

Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. These questions take on a particular importance in philosophy for two reasons. Firstly, there is a view concerning the metaphysics of time, known as the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Instead, the world is a four-dimensional space-time block, lacking any of the apparent dynamic features of time. If the B-theory is correct, as the book argues, then it must be explained why our experiences seem to tell us otherwise. Secondly, experiences of temporal features such as changes, rates and durations are of independent interest because of certain puzzles that they raise, the solutions to which may shed light on broader issues in the philosophy of mind.

This book offers a detailed and fascinating picture of the astonishing astronomical knowledge on which the Roman calendar, traditionally attributed to the king Numa Pompilius (reign 715-673 B.C.), was based. This knowledge, of Mesopotamian origins, related mainly to the planetary movements and to the occurrence of eclipses in the solar system. The author explains the Numan year and cycle and illustrates clearly how astronomical phenomena exerted a powerful influence over both public and private life. A series of concise chapters examine the dates of the Roman festivals, describe the related rites and myths and place the festivals in relation to the planetary movements and astronomical events. Special reference is made to the movements of the moon and Venus, their relation to the language of myth, and the particular significance that Venus was considered to have for female fertility. The book clearly demonstrates the depth of astronomical knowledge reflected in the Roman religious calendar and the designated festive days. It will appeal both to learned connoisseurs and to amateurs with a particular interest in the subject.

Originally published in 1926, this book contains a general history of the measurement of time now known as the week. Colson begins with the seven-day cycle devised by the Jews and examines how different theologies gave rise to different names and systems of measurement for each day of the week and how the week eventually became standardised. This book will be of value to anyone with an interest in ancient astronomy and the history of time keeping.

What can we learn about the world from engaging with fictional time-series? What should we make of stories involving time travellers who change the past, recurrence of a single day, foreknowledge of the future, the freezing or rewinding of time, or time-series which split into alternative courses of events? Do they show us radical alternative possibilities concerning the nature of time, or do they show that even the impossible can be represented in fiction? Neither, so this book argues. Defending the view that a fiction represents a single possible world, the authors show how apparent representations of radically different time-series can be explained in terms of how worlds are represented without there being any fictional world which has such a time-series. In this way, the book uses the complexities of fictional time to get to the core of the relation between truth in fiction and possibility. It provides a logic and metaphysics to deal with the fact that fictions can leave certain features of their fictional worlds indefinite, and draws comparisons and connections between fictional and scientific representations and hypotheses. Utilising the notion of a counterpart, the authors show how to understand claims concerning persistence of characters and their identity across fictions, and what it means for a fiction to be 'set' at an actual time. Consideration is given to motion in fiction, asking whether it is sometimes continuous and sometimes discrete, how to understand different rates of change, and whether fictional time itself can be said to flow.

The critical condition and historical motivation behind Time Studies The concept of time in the post-millennial age is undergoing a radical rethinking within the humanities. Time: A Vocabulary of the Present newly theorizes our experiences of time in relation to developments in post-1945 cultural theory and arts practices. Wide ranging and theoretically provocative, the volume introduces readers to cutting-edge temporal conceptualizations and investigates what exactly constitutes the scope of time studies. Featuring twenty essays that reveal what we talk about when we talk about time today, especially in the areas of history, measurement, and culture, each essay pairs two keywords to explore the tension and nuances between them, from "past/future" and "anticipation/unexpected" to "extinction/adaptation" and "serial/simultaneous." Moving beyond the truisms of postmodernism, the collection newly theorizes the meanings of temporality in relationship to aesthetic, cultural, technological, and economic developments in the postwar period. This book thus assumes that time-not space, as the postmoderns had it-is central to the contemporary period, and that through it we can come to terms with what contemporaneity can be for human beings caught up in the historical present. In the end, Time reveals that the present is a cultural matrix in which overlapping temporalities condition and compete for our attention. Thus each pair of terms presents two temporalities, yielding a generative account of the time, or times, in which we live.

A look at the competing notions of time in the middle ages, from the spiritual - death, the Last Judgement - to the practical - lawyers' calculations, clocks and calendars. By exploring some of the more important senses of time which were in circulation in the medieval world, scholars from a wide range of disciplines trace competing definitions and modes of temporality in the middle ages, explainingtheir influence upon life and culture. The issues explored include anachronism as a feature in earlier senses of time, perceptions of death and of the Last Judgement, time in literary narratives and in music, constructions of timeas used in the professions, and original work on the particular systems and technologies which were used for the keeping of time, such as clocks and calendars. Contributors: PAUL BRAND, PETER BURKE, MARY J. CARRUTHERS, DEBORAH DELIYANNIS, CHRISTOPHER HUMPHREY, ROBERT MARKUS, AD PUTTER, HOWARD WILLIAMS.

Timekeeping is an essential activity in the modern world and we take it for granted that our lives our shaped by the hours of the day. Yet what seems so ordinary today is actually the extraordinary outcome of centuries of technical innovation and circulation of ideas about time.
Shaping the Day is a pathbreaking study of the practice of timekeeping in England and Wales between 1300 and 1800. Drawing on many unique historical sources, ranging from personal diaries to housekeeping manuals, Paul Glennie and Nigel Thrift illustrate how a particular kind of common sense about time came into being, and how it developed during this period.
Many remarkable figures make their appearance, ranging from the well-known, such as Edmund Halley, Samuel Pepys, and John Harrison, who solved the problem of longitude, to less familiar characters, including sailors, gamblers, and burglars.
Overturning many common perceptions of the past-for example, that clock time and the industrial revolution were intimately related-this unique historical study engages all readers interested in how 'telling the time' has come to dominate our way of life.

The Revolution in Time explores the idea that people in Western Europe changed the way they thought about the concept of time over the early modern period, by examining reactions to the 1688-1689 revolution in England. The study examines how those who lived through the extraordinary collapse of James II's regime perceived this event as it unfolded, and how they set it within their understanding of history. It questions whether a new understanding of chronology - one which allowed fundamental and human-directed change - had been widely adopted by this point in the past; and whether this might have allowed witnesses of the revolution to see it as the start of a new era, or as an opportunity to shape a novel, 'modern', future for England. It argues that, with important exceptions, the people of the era rejected dynamic views of time to retain a 'static' chronology that failed to fully conceptualise evolution in history. Bewildered by the rapid events of the revolution itself, people forced these into familiar scripts. Interpreting 1688-1689 later, they saw it as a reiteration of timeless principles of politics, or as a stage in an eternal and pre-determined struggle for true religion. Only slowly did they see come to see it as part of an evolving and modernising process - and then mainly in response to opponents of the revolution, who had theorised change in order to oppose it. The volume thus argues for a far more complex and ambiguous model of changes in chronological conception than many accounts have suggested; and questions whether 1688-1689 could be the leap toward modernity that recent interpretations have argued.

This comprehensive collection of calendars could only have been assembled by the authors of the definitive text on calendar algorithms, Calendrical Calculations. Using the algorithms outlined in their earlier book, Reingold and Dershowitz have achieved the near impossible task of simultaneously displaying the date on thirteen different calendars over a three-hundred year period. Represented here are the Gregorian, ISO, Hebrew, Chinese, Coptic, Ethiopic, Persian, Hindu lunar, Hindu solar, and Islamic calendars; another three are easily obtained from the tables with minimal arithmetic (JD, R.D., and Julian). The tables also include phases of the moon, dates of solstices and equinoxes, and religious and other special holidays for all the calendars shown. These beautifully-produced tables will be of use for centuries by anyone with an interest in calendars and the societies that produce them.

Two systems of timekeeping were in concurrent use in Venice between 1582 and 1797. Government documents conformed to the Venetian year (beginning 1 March), church documents to the papal year (from 1 January). "Song and Season" defines the many ways in which time was discussed, resolving a long-standing fuzziness imposed on studies of personnel, institutions, and cultural dynamics by dating conflicts. It is in this context that the standardization of timekeeping coincided with the collapse of the "dramma per musica" and the rise of scripted comedy and the "opera buffa," Selfridge-Field discloses fascinating relationships between the musical stage and the cultures it served, such as the residues of medieval liturgical feasts embedded in the theatrical year. Such associations were transmuted into lingering seasonal associations with specific dramatic genres. Interactions between culture and chronology thus operated on both general and specific levels. Both are fundamental to understanding theatrical dynamics of the sixteenth to eighteenth centuries.

One Time Fits All provides the first full framework for understanding attributes of civil time, which is used throughout the world today. It focuses on three components of uniform time all linked to the prime meridian at Greenwich-the International Date Line, the worldwide system of Standard Time zones, and Daylight Saving Time (Summer Time)-tracing the story of their beginnings and eventual acceptance from original sources in Europe, Great Britain, Canada, and the United States. The book concludes with an examination of the recent changes in America's Daylight Saving Time that are scheduled to take effect in 2007.

Measuring the daily and yearly cycle of the cosmos has never been entirely straightforward. The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February). Published with the world under threat from chaos arising from the expiry of computer dates after 31st December 1999, this study links politics and religion, astronomy and mathematics, and Cleopatra and Stephen Hawking.

Questions of Time and Tense brings together new essays on a major focus of debate in contemporary metaphysics: does time really pass, or is our ordinary experience of time as consisting of past, present, and future an illusion? The international line-up of contributors broaden this debate by demonstrating the importance of questions about the nature of time for philosophical issues in ethics, aesthetics, psychology, science, religion, and language.

From the bestselling, National Book Award-nominated auhtor of Genius and Chaos, a bracing new work about the accelerating pace of change in today's world.

Most of us suffer some degree of "hurry sickness." a malady that has launched us into the "epoch of the nanosecond," a need-everything-yesterday sphere dominated by cell phones, computers, faxes, and remote controls. Yet for all the hours, minutes, and even seconds being saved, we're still filling our days to the point that we have no time for such basic human activities as eating, sex, and relating to our families. Written with fresh insight and thorough research, Faster is a wise and witty look at a harried world not likely to slow down anytime soon.

This book studies the transition from local to national timekeeping, a process that led to Standard Time--the world-wide system of timekeeping by which we all live. Prior to the railroads' adoption of Standard Railway Time in 1883, timekeeping was entirely a local matter, and America lacked any uniform system to coordinate times and public activities. For example, in the middle of the nineteenth century, Boston had three authoritative times, which differed by seconds and minutes.
The story begins in the 1830s with the building of the first railroads. Since railway safety depended upon maintaining the temporal separation of trains through precise timing, railroads were the first to establish time standards to govern their operations. The railroads' switch to five time standards indexed to the Greenwich meridian inaugurated the modern era of public timekeeping and led directly to cities adopting Greenwich-indexed civil time zones.
Central to the story are those college and university astronomers who, starting in the 1850s, sold time signals to nearby cities and railroads. From the start, they competed with other entrepreneurs trying to make money by selling time. Decades of negotiations, government lobbying, and battles over customers followed, all in the name of "public service." Improvements by a host of clockmakers, civil and electrical engineers, telegraph and railway technicians, and instrument makers finally changed the market for accurate time. Public timekeeping became the realm of business investors.
Despite the efforts of astronomers and various of their Congressional supporters, who argued for the necessity of a national system of time authorized by the federal government, the railroads' success with their own system blocked legislation for a national system of time until the First World War. By then, a single source for correct time dominated the public's timekeeping: the U.S. Naval Observatory's noon signal.
In this first comprehensive, scholarly history of timekeeping in America, the author has drawn upon a rich, untapped archival record, municipal and legislative documents, newspapers, and science and engineering journals to challenge several myths that have grown up around the subject.

Time - relentless, ever-present but intangible and the single element over which human beings have no absolute control - has long proved a puzzle. The author examines the phenomenon of time and asks such fascinating questions as how time impinges on people, to what extent our awareness of time is culturally conditioned, how societies deal with temporal problems and whether time can be considered a resource' to be economized. More specifically, he provides a consistent and detailed analysis of theories put forward by a number of thinkers such as Durkheim, Evans-Pritchard, Levi-Strauss, Geertz, Piaget, Husserl and Bourdieu. His discussion encompasses four main approaches in time research, namely developmental psychology, symbolic anthropology (covering the bulk of post-Durkheimian social anthropology) economic' theories of time in social geography and, finally, phenomenological theories. The author concludes by presenting his own model of social/cognitive time, in the light of these critical discussions of the literature.

The author discusses whether time travel is scientifically possible. He examines "the history of the development of general relativity, the conceptof curved space-time and the early evolution of the universe. The remainder of the book seeks to] explain the problems that arise when we attempt to turntheoretical holes in space-time into time machines." (N Y Times Book Review)

The idea of time travel has tantalized humans for millennia. We can send humans into space, but roaming through time has eluded us. Do the laws of physics demand that we stay trapped in the present? This book examines the past, present and future states of time-travel research, but, also, looks at the bizarre anomalies of time itself.
