Alpha version 0.0.5 of HistoryCal for Windows is released. This version adds the Common Era Julian and Gregorian calendars and the Astronomical Year calendar, a hybrid using the Julian and Gregorian schemes.
The version also introduces the idea of optional fields in a calendar scheme, this makes it easier to create new calendar variants without impacting on other calendars. The HistoryCal script language has also been significantly extended with if/endif and do/loop statements plus other improvements. Work in inhand to fully document the language.
A number of bugs have been fixed, in particular the Christian Liturgical calendars should now work correctly.

The pCalCalc project has been renamed HistoryCal and has moved to a new home at http://historycal.org. It is thought that this new name better reflects the use and target audience of the program.

I am pleased to announce a new project, the Programmable Calendric Calculator, also to be known as pCalCalc.
This project will be the new home of the "Cal" calendar library that was first developed for The Family Pack genealogy program. The pCalCalc application will use the library to allow users to convert dates between different world calendars, calculate ages and work with date ranges. It will also allow the user to extend the range of calendars provided by using a simple script language to create variants of the built-in calendar schemes.
Developer for pCalCalc.
