The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities ("contexts") on that site.For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates.

An example of a practical application of seriation, is the comparison of the known style of artefacts such as stone tools or pottery.

As an example Pinnacle Point's caves, in the southern coast of South Africa, provided evidence that marine resources (shellfish) have been regularly exploited by humans as of 170,000 years ago.

On the other hand, remains as recent as a hundred years old can also be the target of archaeological dating methods.

Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.

Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
