Schaefer[28] points out that the Jewish lunar calendar fixes the Passover date, and this in turn requires the crucifixion to have occurred on either 7 April 30 A.D. or 2 April 33 A.D.

We therefore imagine the stars to remain fixed on a sphere of very large radius with the earth at its centre. We call this sphere the celestial sphere. At any point ...
