What does date bp mean?
BP is a way of expressing the age of an object, as compared to BC or AD. BP is based on the disintegration of carbon. A rough formula for finding BP age from an AD is today's year minus 1950 = a number to subtract from the AD date. For example, an object is dated at 1,000 AD. It is now 2008, therefore 2008 - 1950 = 58. The object date 1,000 AD - 58 = 942 BP. Basically BP is approximately the BC date plus 1950 and the AD date minus today's year minus 1950.
