Review
'Because years, months, and days don't mesh simply, calendar making has been a challenge throughout history. Reingold and Dershowitz'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 tells 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 Seidelmann, Director of Astrometry, U.S. Naval Observatory ' ... something of immense value ... a true labor of love, this cultural service to humanity should be in every library of the world.' Choice "If you are interested in Calendars this book is a must have -- an excellent mind-broadening book." Journal of the ACCU "...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
