Use this template to markradiocarbon dates in articles where is not clear whether the date has beencalibrated. For boxes that can be placed at the top of an article or section, seeTemplate:Clarify radiocarbon calibration.
Check the cited source to verify whether the date is calibrated or not and clarify if as appropriate. Calibrated radiocarbon dates are denoted withcal BP orBC/BCE in scientific literature. Uncalibrated dates may be reported asuncal BP,bp (lowercase), orka.BP usually refers to calibrated dates, but can be ambiguous in some contexts (e.g. older sources on palaeoanthropology and Palaeolithic archaeology).
Individual radiocarbon dates reported in Wikipedia articles should generally match the format given in their sources. Do not attempt to calibrate an uncalibrated date yourself, as this isoriginal research. It may be appropriate to convert calibrated BP dates to the BC/BCE calendar to maintain consistency within an article (but never uncalibrated BP).
If you cannot find a source for the date, replace this tag with{{citation needed}} or remove it.
