Dendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was invented and developed during the 20th century originally by A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona. The technique can date wood to exact calendar years.

Dendrochronology is a technique that uses the annual rings of trees in temperate climates to estimate a tree’s age. Some trees can live for thousands of years, so this technique is useful in dating trees from 3,000 to 4,000 years before present, but it has also been used in fossil trees from further back in Holocene time.

Dendrochronology is not only a method for tree dating, but also a method used by archeologists to date any wooden material.
The tighter the layer is, the colder was the climate was and vice versa. So by comparing the sequences with the climate reports, the archeologist can estimate more or less precisely when tje artefact was made.

Dendrochronology is the dating and study of annual rings in trees.
The word comes from these roots:
ology = the study of
chronos = time; more specifically, events and processes in the past
dendros = using trees; more specifically, the growth rings of trees

It's a method of dating trees, by analyzing tree-ring growth patterns. Most trees grow one ring every year, at least in temperate climates. The size and width of the ring is affected by particular atmospheric conditions in the duration of each year (and I'm generalizing). Scientists can evaluate the age of trees by comparing these naturally occuring patterns of rings with that of similar trees in a specific region.
It gets much more complicated, and a lot less interesting, but I'll link to wikipedia if you want to check it out!
