calculate cal BP ages from BC/AD ages
Description
calculate cal BP ages from BC/AD ages
Usage
BCADtocalBP(x, zero = TRUE)
Arguments
x |
The BCAD age(s) to be translated into cal BP age(s). BC ages are negative, AD ages are positive. |
zero |
Whether or not zero BC/AD should be included. Defaults to 0. |
Details
Turn BC/AD (or BCE/CE) ages into cal BP ages. Negative ages indicate BC, positive ages AD. Since the Gregorian and Julian calendars do not include 0 BC/AD (i.e., 31 December of 1 BC is followed by 1 January of AD 1), zero can be omitted. The years then go from 1 (AD) to -1 (i.e., 1 BC). Other calendars, such as the astronomical one, do include zero. The often-used BCE/CE ages are equivalent to BC/AD.
Value
The cal BP age(s).
Examples
BCADtocalBP(2024)
BCADtocalBP(-1, zero=TRUE)
BCADtocalBP(-1, zero=FALSE)
