Welcome to the latest release of HistoryCal, an ambitious multi-platform historical date and calendar calculator.

For more details and links to a compiled version for Windows (10 and 11) and the source code, please visit the website at http://historycal.org

To build the the program on Windows with Visual Studio 2022, the following should work:-

git clone --recurse-submodules https://github.com/nickmat/HistoryCal.git
cd HistoryCal\build
.\cmake-vc-working.bat
vc-working\hcal.sln

If all goes well, this will open Visual Studio 2022 (or later) with all the source files, including third-party ones, available to build the HistoryCal program under the project name "hcal".
