My site offers three programs created in the course of my work in the history of medieval and oriental astronomy.

The latest addition is the StarList, based on the Yale Bright Star List, and adapted to the study of the Ptolemaic list of stars.
Please go to the Menu item on the left.

The main program is Kairos designed as a general calendar conversion program.

Kairos 4.0 includes all the features of Kairos 3.0, but now in addition is thoroughly Unicode based, and includes a presentation of lunar and solar eclipses.

Upgrade: If you have downloaded Kairos before 30 Sept 2008, please copy it again, because there have been some corrections.
 
 

Now Fontlist has been extended to Word 2007: Download  Fontlist6

- This is still a beta version, and I would be glad to hear of any problems. Be sure to get the latest copy.

For a survey of some of the calendars in Kairos and the problems of computation, download and read my article
"Computation for Calendars" : Cerisy from the Cerisy (Normandy) workshop on calendars (July 2000).

Freeware :
Fontlist 5 and Fontlist 6 were developed in order to make it easier to handle a variety of fonts when using MS Word, amd now Word 2007. Both are fully unicode compliant, listing the fontname in appropriate CJK characters. It will open any file, even when the filename consists of non-ascii characters.

Hanfind is designed to exploit the database UniHan.txt provided by Unicode. Hanfind provides, among other features, a list (sorted by tones)of all the Chinese characters for a given Pinyin reading.

Unicode Search is for those people who have hundreds of fonts on the disk, and need to know which will cover a given set of Unicode blocks. For example if you need to type Classical Greek, you need the blocks "Greek" and "Greek extended". If you want to transcribe oriental languages, you need besides the usual Latin blocks, also "Latin extended Additional". Do you really know which fonts you have for that ? Unicode Search has the answer ! And it's free !
