Book Description
Astrology, Almanacs, and the Early Modern English Calendar is a handbook designed to help modern readers unlock the vast cultural, religious, and scientific material contained in early modern calendars and almanacs. It outlines the basic cosmological, astrological, and medical theories that undergirded calendars, traces the medieval evolution of the calendar into its early modern format against the background of the English Reformation, and presents a history of the English almanac in the context of the rise of the printing industry in England. The book includes a primer on deciphering early modern printed almanacs, as well as an illustrated guide to the rich visual and verbal iconography of seasons, months, and days of the week, gathered from material culture, farming manuals, almanacs, and continental prints. As a practical guide to English calendars and the social, mathematical, and scientific practices that inform them, Astrology, Almanacs,and the Early Modern English Calendar is an indispensable tool for historians, cultural critics, and literary scholars working with the primary material of the period, especially those with interests in astrology, popular science, popular print, the book as material artifact, and the history of time-reckoning.

Book Description
The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
