It is one of the most accurate methods of absolute dating used in Archaeological Anthropology because it can determine the exact calendar year in which a tree was cut down, provided suitable wood samples and reference chronologies are available.

The width of each ring depends on environmental conditions such as rainfall, temperature, soil fertility, sunlight, and disease. Favorable years produce wider rings, while unfavorable years result in narrower rings. Since trees growing in the same geographical area experience similar climatic conditions, they develop comparable patterns of wide and narrow rings. These distinctive patterns serve as natural chronological records. The basic principle of dendrochronology is cross-dating. In this method, the sequence of growth rings from a piece of archaeological wood is matched with
