Book Description

ISBN-10: 0521777526 | ISBN-13: 978-0521777520 | Publication Date: August 6, 2001 | Edition: 2nd

This new edition of the successful calendars book expands the treatment of the previous edition to new calendar variants. It frames the calendars of the world in a completely algorithmic form. The authors describe fourteen calendars and how they relate to one another: the present civil calendar (Gregorian), the recent ISO commercial calendar, the old civil calendar (Julian), the Coptic and (virtually identical) Ethiopic calendars, the Islamic (Moslem) calendar; the Baha'i, the Hebrew (Jewish) calendar, the Mayan calendars, the French Revolutionary calendar, the Chinese calendar, and both the old (mean) and new (true) Hindu (Indian) calendars. 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 for computer use with LISP and Java code for all the algorithms included on CD, and updates available on the Web.

Editorial Reviews

Review

"The work is attractively produced and well written, in a crisp and lucid style, its earnest content lightened by touches of humor and details of history that communicate most effectively the authors' enthusiasm for and knowledge of their subject. The book's major contribution is that, for the first time, it places an authoritative computational specification of all these calendars in the public domain. Indeed, this book supplies the essential tools to enable us to proceed cogently and efficiently toward correlation of all these derivative calendrical systems, and Dershowitz and Reingold are to be congratulated on making such strides toward this goal."

Book Description

This new edition of the successful calendars book is being published at the turn of the millenium and expands the treatment of the previous edition to new calendar variants. 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. The book gives a description of fourteen calendars and how they relate to one another. Easy conversion among these calendars is a byproduct of the approach, as is the determination of secular and religious holidays. Calendrical Calculations makes accurate calendrical algorithms readily available for computer use with LISP and Java code included on CD. This new edition will be a valuable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists.

5.0 out of 5 stars Everything you ever wanted to know about calendars!, July 20, 2000

The first edition was a masterpiece, but this one is evenbetter! I've been involved in proof reading the new edition, and I'veread the final draft. There are lots of popular books out there about calendars and the history of calendars. Unfortunately, most of them are filled with mistakes, especially when they talk about non-European calendars. The purpose of this book is to both give reliable information about the different calendars and to provide software for calendrical computations. My own field is the Chinese calendar, and this is one of only two books that gets it right (the other is the Explanatory Supplement to the Astronomical Almanac). If you want to get the facts, there's no other comparable book. Remember to check out the web site of the authors to get the software and check out the applets. END

I highly recommend the book if you are interested in calendars as a hobby. If you are using this book for a project I suggest you look at this soley as a reference, since you will have to look elsewhere to have something you can use. The bibliography included is a good source.

The details and discussions of how they approach problems like the visibility of sunset are amazing and really opened my eyes to the difficulties of creating an accurate calendar under different systems. This book covers everything I could think of and quite a few ideas I would never consider.

I would give it 5 stars, except that the code and algorythms provided in the book are copyrighted and can not be used without explicit permission of the authors. I contacted the authors for a project I had, but it was determined that I could not use their algorithms since I intended to release under GNU license.

5.0 out of 5 stars Anonymous's criticisms baseless, October 26, 2004

The previous review criticizes us for having a lengthy document reporting errata--but most of that document is not errata at all, but notes with extra material! C.U.P. introduced 10 spots where some lines were lost in the 2nd printing; when that was discovered they withdrew the printing and filled all orders with the hardback first printing.

Perhaps "anonymous" would have been happier if we did not share the details of errors with readers, but we feel it is in the reader's interest to have the errata open to public.
