Absolute dating, also sometimes called chronometric dating, is the process of determining an age on a specified chronology in archaeology and geology. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.

Techniques include (amongst others): radiocarbon dating, potassium-argon dating, thermoluminescence dating, and amino acid racemization.

In The Future of the Past: Dating archaeology using radiocarbon and particle accelerators Tom Higham of the University of Oxford examines some of the projects the Radiocarbon Accelerator Unit has been involved with over the last few years; from dating the Neanderthal extinction, to identifying the bones of Richard III and Alfred the Great.

Whilst in Carbon Dating: The Science of When Things Happen he discusses the way in which scientists establish the age of ancient and prehistoric artefacts.
