.: Chinese Calendrics Testimonials :.

I am still using CHCAL, every time I open my family tree for updating. It has been and continues to be the best Chinese-English calendar program so far.

My interests are ancient Chinese and Mongolian coinage. From time to time I have to get exact data for some dates in Chinese medieval sources. In this case the most accurate and useful tool is the Chinese Calendrics program which helps me to get data for my publications.

I use this program not only for Chinese Lunar events, but also to fix Hindu and Buddhist festivals (which mostly are tied to aspects of the moon). It is very easy to use, and flexible enough to do these extra calendar fixes.

It is a great software.

I'm really glad I found this software, it is so much easier for a quick lookup than the time consuming calculating, even though it takes a bit in the beginning to know how to use it. But once that's done, you're a lucky winner :)

Your programme Chinese Calendrics is the best for transferring lunar data to our system that I have found. I use it often for data from Chinese historical sources.

A great program for all who work in two worlds -- the Western (Julian Calendar) and the Eastern (Lunar or Sol-Lunar Calendar). This program makes it easy!

I use your program to verify dates of translated inscriptions about lunar observations relating to archaeoastronomy. Recently I used your program to help verify the age and accuracy of several inscriptions relating to famous and other lesser known historical personages. It is a fabulous and extremely accurate time-saver for having to calculate everything by hand. I especially like the ability in your program to determine the Julian Date for the beginning of each Chinese Lunar Year. This helps me calculate some of the more esoteric elements of Chinese, Hermetic and Uranian systems with greater precision.

I am an American who has lived and worked most of his adult life in Asia, including Vietnam, Thailand, India and Afghanistan, I have found that understanding the calendar systems used by these countries is a useful way to add a valuable dimension of understanding the different cultures. Though written for the Chinese calendar, studying the tremendous amount of information contained in and offered by the program allows one to apply his understanding to the various other regional cultures. This is most easily done for the Vietnam calendar of course, but it does not take much study to apply the uses of the program to the lunar calendars used in Thailand, India and even the Moslem cultures found in Afghanistan and Middle East. I use the program frequently.

A spectacular value that saves hours of tedious calculation when translating inscriptions and documents.

Great program, it has been very useful as I need to do lots of calculations of solar terms, moon phases, etc. ..

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.

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.

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.
