The OxCal program is intended to provide radiocarbon calibration and analysis of archaeological and environmental chronological information.
The current version is 4.2 and works with IntCal13. 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:OxCal online
The program can also be downloaded for use on your own computer (Windows, Mac OSX or Linux with the current version of Firefox, using a special Firefox add-on):OxCalDistribution.zip (~3MB)
Please see the installation instructions.
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 IntCal13 and Marine13 data files are bundled with OxCal (with the kind permission of the compilers). Full details are given in Radiocarbon Vol 55(4) (IntCal13 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):

The current version of OxCal is compatible with the latest Firefox release. However, you cannot use Firefox v17 or later to run older versions of OxCal (v4.2.2 and earlier) as a standalone program as the extensions required have been removed. The latest compatible version of Firefox that will work for this is archived here:
Version was 3.10 which was a Windows standalone program; this is still available above but will not be further developed.
The manual for this version is available here.
