Overview

This new edition of the popular calendars book expands the treatment of the previous edition to new calendar variants: generic cyclical calendars and astronomical lunar calendars as well as the Korean, Vietnamese, Aztec, and Tibetan calendars. As interest grows in the impact of seemingly arbitrary calendrical systems upon our daily lives, this book frames the calendars of the world in a completely algorithmic form. Easy conversion among these calendars is a by-product of the approach, as is the determination of secular and religious holidays. Calendrical Calculations makes accurate calendrical algorithms readily available. The fascinating historical settings, general calendar descriptions, and lavish illustrations will appeal to anyone with an interest in religion, history, astronomy, or is just curious about calendars.

Editorial Reviews

Booknews
Of interest to historians studying or using calendar systems, of course, but also to business people who want the correct date on automated letters to potential clients in Persian, China, and Ethiopia; for a planner who wants the new Cairo store to open at the end of Ramadan ten years from now; computer programmers developing software for such applications; and so on. In algorithmic form, explains 14 calendars and the calculations for converting between them. Among them are the recent ISO commercial calendar, Gregorian, Julian, Coptic, Bah<'a>'<'i>, French Revolutionary, Mayan, and old and new Hindu. Includes source code. Annotation c. by Book News, Inc., Portland, Or.
From the Publisher
"Because years, months, and days don't mesh simply, calendar making has been a challenge throughout history. Dershowitz and Reingold's compendium, here in its third edition, has already established itself as the definitive reference on calendrical structures. Their manual displays conversions between all the major calendar systems as well as between many fascinating schemes from bygone civilizations." Owen Gingerich, Harvard-Smithsonian Center for Astrophysics

"One of the most fascinating books I've read all year. Takes chronology into the computer age with impressive erudition and elan. Just finding out what the calendar rules are is usually close to impossible; Calendrical Calculations tell you how to use them too. A must for everyone who worries about days, months, years - and why they never quite fit." Ian Stewart

"A good, comprehensive documentation of software for calculating dates on very many calendars." P. Kenneth Seidlmann, Director of Astronomy, U.S. Naval Observatory

"One of those rare books that is both an authoritative reference source and a fun read." Danny Hillis

"The book is a definitive account of the world's major calendars and how to use them. It will be of interest not only to mathematicians, but also to historians and laymen. The authors are to be congratulated on a splendid research job." Martin Gardner

"This book must surely become the standard work on calendar conversions. No historian, chronologist, or recreational mathematician should be without it." E.G. Richards, Nature

Meet the Author

In addition to his expertise on calendars, Nachum Dershowitz is a leading figure in software verification in general, and termination of programs in particular; he is an international authority on equational inference and term-rewriting. Other research interests of his include program semantics and combinatorial enumeration. Dershowitz has authored or co-authored over one hundred research papers and several books and has held visiting positions at prominent institutions around the globe. He has won numerous awards for his research and teaching. He was born in 1951 and his graduate degrees in Applied Mathematics are from the Weizmann Institute in Israel. He is currently a Professor of Computer Science at Tel-Aviv University.

Edward M. Reingold was born in Chicago, Illinois in 1945. He has an undergraduate degree in Mathematics from Illinois Institute of Technology and a Ph.D. in Computer Science from Cornell University. Reingold has been at the University of Illinois at Urbana-Champaign since 1970; he now a Professor of Computer Science there. His research interests are in theoretical computer science, especially the design and analysis of algorithms and data structures. A Fellow of the Association for Computing Machinery since 1995, Reingold has authored or co-authored over fifty research papers and nine books; his papers on backtrack search, generation of combinations, weight-balanced binary trees, and drawing of trees and graphs are considered classics. He has won awards for his undergraduate and graduate teaching. Reingold is intensely interested in calendars and their computer implementation: in addition to Calendrical Tabulations and Calendrical Calculations, he is the author and maintainer of the calendar/diary part of GNU Emacs.
