(Examples of each method, respectively, are dendrochronology, carbon-14, archaeomagnetism, and the known year a city was destroyed.) Relative dating is based on stratigraphy (the tendency of younger layers to lie over older layers) and comparison of artifacts from undated sites to sites where dates are established.

All dating methods have limitations and can be complicated by turbation, or mixing, of layers by human or natural actions.

The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place.

Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.

Thus, 3700 Tree-ring dating: Most trees produce a ring of new wood each year, visible as circles when looking at the cross section of a piece of wood.

If we knew the precise length of reign for every Egyptian king, chronology would be no problem.

However, we do not even know the number of kings for all periods, and there is also the possibility that reigns overlapped by coregency or in times of political disunity.

Typological dating may foster the tendency to assume that each step in development is of about the same time length, but this does not need to be the case in reality.

All living organic materials contain Carbon-14 atoms in a constant number.

Artefacts often have a distinctive style or design, which developed over a period of time.
