Radiocarbon is produced in the upper atmosphere after Nitrogen-14 isotopes have been impacted by cosmic radiation.

Absolute dating represents the absolute age of the sample before the present.

Historical documents and calendars can be used to find such absolute dates; however, when working in a site without such documents, it is hard for absolute dates to be determined.

The Mayan calendar used 3114 BC as their reference.

More recently is the radiocarbon date of 1950 AD or before present, BP.
