Yes and no because when Christ was born or BC that was sentorian time. Sentorian time (spelling maybe?) has to do with sunrise and sunset and I belive the cycles of the moon. Good Friday is that so that was Last supper, Easter is Sunday yet the tell is 3 DAYS between Christ born and risen. The reason is Sentorian time or BC was shorter. The AD calender does not fall in sync with the BC calander which is based on Christ is risen not on christs birth. I have not researched this but I know the Jewish Holiday Calander revolves based on BC or sentorian time. Perhaps the birthday of Christ was when Christ was rizen but not a scholoar just someone who goes through life like Forrest Gump without being a disgusting pedo or canibal or sicko. I am guided by the love of God, truth and serindipidous information and conatces as well as God's luck and I appreciate every second of it.
