An absolute location is? must contain the terms ce/bce explains the reasons events happened puts events in context with one another identifies events and the effects of those events on a place

he ad/bc notation was first proposed by the monk dionysius exiguus (dennis the little) in the year 525 ce. he used it to identify the years in the easter tables that he prepared. he did not use the notation to date historical events. "dionysius implied, but never stated, that jesus was born 25 december 1 bc." 1 the basis on which he linked the divide between bc and ad to the birth of jesus is unknown. there is general agreement that he guessed incorrectly. most theologians and religious historians believe that yeshua of nazareth (jesus) was born during a fall -- or less likely during a spring, sometime between 7 and 4 bce. however, we have seen estimates as as early as the second century bce and as late as 4 ce.

according to wikipedia:

"another calculation had been developed by the alexandrian monk annianus around the year ad 400, placing the annunciation on march 25, ad 9 (julian) -- exactly 8 [sic] years after the date that dionysius later calculated. this era of incarnation was dominant in the east during the early centuries of the byzantine empire, and is still used today in ethiopia, accounting for the 8 or 7-year discrepancy between the gregorian and the ethiopian calendar." 3

"the anno domini era became dominant in western europe only after it was used by the venerable bede to date the events in his ecclesiastical history of the english people, completed in 731" ce.
