Chinese Calendrics Testimonials

For some time I had been looking for a program the would provide me with both Western and Chinese Lunar and Solar Calendar information, all on one screen page in a graphically simple format, I came across just such a program called Chinese Calendrics. I was more than pleasantly surprised by what I had found. There is so much information on one screen that it is truly mind-blowing, but it is shown in an undaunting manner. This program not only graphically shows the daily phase of the moon, which can be advanced by one minute, right up to 80 years at a time, it also compares the differences on-screen between the Western and the Chinese calendars, and a nice facet of this truly amazing program is that with the touch of a button it will give the date of the next Chinese New Year, along with all the relevant Chinese astrological information. It has completely satisfied my requirements and more. There is so much more to this program that one has to use it to appreciate its true virtue. It is a scholastically mathematical masterpiece of software, however, for all its transparent mathematical complexity it has been designed to be completely user-friendly. Having used this program for some time now, it is easy to use and I would not hesitate to recommend it to anyone who has an interest in both the Western and Chinese calendars.

Many people try to write a program for the Chinese calendar without first really understanding the astronomical rules. The author of this program has done his homework, and the result is impressive.

Since the Chinese calendar is very complex, and this program does not shy away from the details, it may seem overwhelming to a casual user. But if power, accuracy and reliability are important, this is the program for you.

If you are interested in doing careful analysis of the Chinese calendar, for historical, astronomical or astrological purposes, there is no other alternative.

The Mathematics of the Chinese Calendar

My research focuses on the Khmer civilization from Angkorian times to the present. I purchased three Hermetic Systems tools: Easy Date Converter, Lunar Calendars and Chinese Calendrics. Each one is an excellent, well designed, well documented piece of software. They have proven themselves indispensable in my work.

My most recent project is translating the biography of Cambodian dancer, published in French in 1919. Not a single Western calendar date appears in the text. Using the extraordinary Chinese Calendrics program, I was able to pinpoint multiple event dates as the text gives clear descriptions of festivals based on the cycles of the moon and the Chinese zodiac. This small feat enhanced the historical value of the entire text.

In closing I must also praise the excellent technical support provided. The programs are clear and well documented, but I did have a few technical questions. In each case I received a fast, detailed solution.

I stumbled on your software thru the google search. I tried out many conversion softwares until I hit yours. I found that to be the most suitable and very pro.
