Now scientists tell us that the date is likely to have been in June, 2 BC.
Historically, 4 BC looks a better bet, though.
If the older date is true, it will lengthen the time of Christ's Ministry which has previously been considered to have been about three years.
It also makes Jesus older than the 33 postulated - which makes much sense as he was otherwise rather on the young side to have been accepted by the populace as a legitimate rabbi.
