Usage notes
editA year designation alternative to the widely-used but Christian-oriented designations BC and AD and their secular equivalents BCE and CE. Used in historical sciences, especially when the exact number of years is unknown, and where precision and the current year are not significant.
Conventionally, “present” refers to the origin of practical radiocarbon dating in the 1950s, sometimes made explicit with the abbreviation RCYBP (“radio carbon years before present”).
Derived terms
edit- myBP (“million years before present”)
- C14YBP, RCYBP (“radio carbon years before present”)
