Relative dates are established by stratigraphy and by the typological method.

The stratigraphic method, which observes the sequence of earth strata containing artifacts, makes it possible to attribute each stratum to a definite epoch. The typological method is based on the fact that the types of objects and the material from which they were made were different in various historic epochs.

Estimating age in the archaeological record is the primary step in understanding the human past.

Chronology provides a temporal dimension that distinguishes archaeology, paleontology, and geology from the disciplines of ethnography and ethnology.

Theoretically, floating chronologies which cannot be tied to an absolute date (e.g.

certain dendrochronological sequences) are relative chronologies even though the techniques are essentially chronometric.

the determination of the chronology of events studied from archaeological data.
