‘Splain AD, BC, BCE, BP, YBP, BCE and CE when you get a chance.
A hotlink will be ideal.
Thanks.
AD = Anno Domini
BC = Before Christ
BCE = Before Christian Era
BP = British Petroleum
YBP = ???
CE = Christian Era
The two unfamiliar ones for most will be BP (Before Present) and YBP (Years Before Present) which are used for scientific dating methods, such as the Accelerator Mass Spectrometry mentioned in the text.
