Frequently Asked Questions
What does BP, BCE, and CE mean on the timeline?
“BP” stands for “Before Present” and is used when referring to the far distant past. On this timeline, we use it to refer to the “numbers of years before the present day” (e.g. 100,000 BP = 100,000 years ago).
“BCE” stands for “Before the Common Era” and is used to replace “BC” (Before Christ) and therefore provides a religiously neutral way to reference dates within the Gregorian Calendar.
“CE” stands for “Common Era” and is used to replace “AD” (Anno Domini – “In the year of our Lord”) and therefore provides a religiously neutral way to reference dates within the Gregorian Calendar.
