Calculations - University of Oxford Calendar and BP dates Output and input can be given in terms of calendar years yCAL (AD BC) or years before 1950 yBP (cal BP) The relationship between these is simply: yCAL = 1950 - yBP Thus: 10BP = 1940AD, 11950BP = 10000BC
Before Present - Wikipedia Conversion from Gregorian calendar years to Before Present years is by starting with the 1950-01-01 epoch of the Gregorian calendar and increasing the BP year count with each year into the past from that Gregorian date For example, 1000 BP corresponds to 950 AD, 1949 BP corresponds to 1 AD, 1950 BP corresponds to 1 BC, 2000 BP corresponds to

BCADtocalBP: calculate cal BP ages from cal BC AD ages in rice . . . Turn cal 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 (i e , 1 BC) to 1 AD
Geniet: Conversion of Radiocarbon dating When dealing with radio carbon dates, one has to remember that the measured date is not the calendar date For this one has to calibrate the radio carbon date Uncal BP (in former times written as bp or as bc [=Uncal BP-1950]) towards the calendar date BP or BCE (in former times written as Calbc)
