The OxCal program is intended to provide radiocarbon calibration and analysis of archaeological and environmental chronological information.
The current version is 4.4 and works with IntCal20. It is available for online use or downloading.
A variety of different chronological models can be included in the analysis. The information for such analysis can be entered using the user interface or in the form of text command files.
This version is available for online use or download. Please follow the following link to sign on or get a password:
The program can also be downloaded for use on your own computer with the NodeJs software:
Please see the installation instructions for further details.
Please report any bugs or problems to the OxCal discussion group.
In order to prevent the proliferation of different calibration curve files this program has been designed to work with the files provided with the CALIB (*.14c) or the Groningen program (*.dta).
The IntCal20, SHCal20 and Marine20 data files are bundled with OxCal (with the kind permission of the compilers). Full details are given in Radiocarbon (IntCal20 special issue).
An EMail distribution list is held of people who might be interested in announcements about updates and changes to this program:
There is also a discussion group for those interested in discussing use of the program, reporting bugs or suggesting improvements (members can send mail to this group but not the announcement list):
