Current calibration methods for single and replicate 14C dates are compared. Various forms of tabular and graphic output are discussed. Results from all the methods show reasonable agreement but further methodological development and improvements in computer output are required.

We recommend that calibrated dates should be presented as a combination of graphs and ranges, in preference to mean and standard deviation.
