Current dendrochronology archives are only available in ten-year blocks rather than year by year.The lack of data means that archaeologists have to rely on sparse evidence for dating the history of Western civilisation before 763 CE, and Chinese history is only widely agreed from 841 CE.This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).

The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.

If more Miyake events could be found, then tree-ring data taken from archaeological items and carbon-14 data could be used to determine when historic events occurred exactly.

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.

They often have to rely on ancient records of rare astronomical events such as the Assyrian eclipse, a solar eclipse which occurred on the 15 June 763 CE to estimate the age of historical events.

Radiocarbon dating currently provides the best estimates, but are only accurate to within 200 to 300 years.
