At a more coarse-grained level, "Calendrical Calculations" by Dershowitz and Reingold is very interesting. It describes many different world and historical calendar systems, and includes lisp code to convert between them. Among many other problems, converting…
Calendar time, when it is done truly right, is a complicated topic. There's a nice book that has way more detail on this than most people actually would want (Calendrical Calculations, https://www.amazon.com/Calendrical-Calculations-Nachum-Dersh...).
"Easter is a feast, not a planet." --Johannes Kepler A good reference for anyone who has to write calendar related code is the book "Calendrical Calculations" by Dershowitz and Reingold [1]. [1] https://www.amazon.com/Calendrical-Calculations-Nachum-Dersh...
我强烈推荐阅读 Edward Reingold 和 Nachum Dershowitz 写的《Calendrical Calculations》。它是计算机科学与历法系统的绝美结合。另外正如书中所讲，希伯来历确实堪称一个奇迹。
I highly recommend reading Calendrical Calculations, a book by Edward Reingold and Nachum Dershowitz. It is a beautiful combination of computer science and calendar systems. Also, the Hebrew calendar truly is a marvel, as the book goes through.
…card catalog. This is what I miss about technical bookstores. Serendipity. And computers can't yet duplicate that, since what is serendipitous often has nothing to do with me until I find it. I found Calendrical Calculations on the shelf at SoftPro books in Centennial, while just generally browsing. I have never before, and never since, bought a book about calendar systems. What I like most about it was the historical treatment…
从更粗粒度的层面来看，Dershowitz 和 Reingold 写的《Calendrical Calculations》（历法计算）非常有趣。它介绍了世界上许多不同的以及历史上存在过的历法系统，还包含了在它们之间相互转换的 Lisp 代码。在众多其他问题中，转换……

历法时间要想真正做对，是个极其复杂的话题。有本好书在这方面讲的细节，其实远比大多数人真正想知道的要多得多（《Calendrical Calculations》，https://www.amazon.com/Calendrical-Calculations-Nachum-Dersh...）。

同理，还有 Reingold 和 Dershowitz 写的《Calendrical Calculations》。

……图书卡片目录。这就是我怀念专业技术书店的地方。机缘巧合（serendipity）。而且计算机现在还复制不了这种体验，因为所谓的意外之喜，往往是在你偶然发现它之前，跟你八竿子打不着的东西。当年我在 Centennial 的 SoftPro 书店闲逛时，就在书架上偶然发现了《Calendrical Calculations》。在这之前或之后，我再也没买过任何关于历法系统的书。我最喜欢它的一点是对历史背景的处理……
