 Such censuses were taken every fourteen years. And from A.D. 20 until about A.D. 270 we possess actual documents from every census taken. If the fourteen-year cycle held good in Syria this census must have been in 8 B.C. and that was the year in which Jesus was born. It may be that Luke has made one slight mistake. Quirinius did not actually become governor of Syria until A.D. 6; but he held an official post previously in those regions from 10 B.C. until 7 B.C. and it was during that first period that this census must have been taken.
