calBPtoBCAD: calculate BC/AD ages from cal BP ages

Description

calculate BC/AD ages from cal BP ages

Usage

calBPtoBCAD(x, zero = TRUE)

Value

The BC/AD age(s). BC ages are negative, AD ages are positive.

Arguments

x

The calBP age(s) to be translated into BC/AD ages.

zero

Whether or not zero BC/AD should be included. Defaults to 0.

Details

Turn cal BP ages into BC/AD (or BCE/CE). Negative ages indicate BC, positive ages AD. Since the Gregorian and Julian calendars do not include 0 BCAD (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 (i.e., 1 BC) to 1 AD. Other calendars, such as the astronomical one, do include zero. The often-used BCE/CE ages are equivalent to BC/AD.

Examples

 calBPtoBCAD(2024)
 calBPtoBCAD(1945:1955, zero=TRUE)
 calBPtoBCAD(1945:1955, zero=FALSE)
