The definitive guide to calendars
Reingold and Dershowitz present a comprehensive review of calendars, and it is suitable for all people having
an appreciation for mathematics or/and history.
Throughout, the authors' knowledge of and passion for calendars is clearly evident.
This third edition has been expanded to include the following new types of calendars: generic cyclical and
astronomical lunar calendars as well as the Korean, Vietnamese, Aztec, and Tibetan calendars. -Significant
additions indeed, which from what I hear are not found so comprehensibly in most books on calendars.
Attention to detail in the text is excellent, with a comprehensive index of (very minor) errors provided.
Comprehensive Lisp code for the calendars is provided, which I suspect many lay people (including myself) are
not proficient in. -Perhaps generic mathematical logic based routines or a language more widely used such as
JAVA would help?
However, I found the non programming oriented mathematics and history of the text excellent, and thus overall
a detailed and interesting read that is a considerable advancement on it's previous renowned editions.
Scope for future editions?
It may be nice to see each calendar dealt with on it's own, such that one does not necessarily have to convert
between them.
