In this way, calibration tables have been developed that eliminate the discrepancy.
One of the implied assumptions in radiocarbon dating is that levels of atmospheric carbon-14 have remained constant over time.
This turns out not to be exactly true, and so there is an inherent error between a raw "radiocarbon date" and the true calendar date.
Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.
Carbon-14 has a half-life of about 5730 years, so researchers use the process to date biological samples up to about 60,000 years in the past.
