Uncalibrated radiocarbon dates should be clearly noted as such by "uncalibrated years BP", because they are not identical to calendar dates.
Uncalibrated radiocarbon ages can be converted to calendar dates by means of calibration curves based on comparison of raw radiocarbon dates of samples independently dated by other methods, such as dendrochronology (dating on the basis of tree growth-rings) and stratigraphy (dating on the basis of sediment layers in mud or sedimentary rock).
Such calibrated dates are expressed as cal BP, where "cal" indicates "calibrated years", or "calendar years", before 1950.
"Radiocarbon ages" are calculated from f M using the exponential decay relation and the "Libby half-life" 5568 a.
The ages are expressed in years before present (BP) where "present" is defined as AD 1950.
I'd say it's decent at what it does, so you could be successful in finding the Justin Bieber to your Selena Gomez or — to reference a couple that's still together — the Zayn Malik to your Gigi Hadid.
