One of the most essential aspects of archaeology is dating objects from the past, and one of the most critical tools in dating historic objects is dendrochronology.

Dendrochronology, also called tree ring dating, is a scientific method used to determine the age of wood and to reconstruct past environmental conditions by analyzing growth rings in trees.

However, it isn't just a matter of counting tree rings.

There's a science to it that has allowed us to understand a great deal about our past.

Learn more about dendrochronology, how it works and how it's used on this episode of Everything Everywhere Daily.

Dating events and items from the past is an important part of science. Scientists have

provided dates for everything from the age of the

universe to items that have been found in ancient tombs. However, there is no one way to date an object.

There are multiple ways to date things, and depending on what's being dated, researchers will

use a different technique. In one of the very early episodes of this podcast, I covered the topic of radiometric dating.

Radiometric dating involves using the known decay rate of radioactive isotopes to estimate the ages of things like rocks.

Uranium, potassium, and other elements can be used for such dating.

Carbon 14 is another type of dating that doesn't work with rocks but can be used

for organic matter going back about 60,000 years. But one of the best methods for dating more
