Now when he was crucified darkness came over all the world; the sun was altogether hidden, and the sky appeared dark while it was yet day, so that the stars were seen, though still they had their luster obscured, wherefore, I suppose your excellency is not unaware that in all the world they lighted their lamps from the sixth hour until evening. And the moon, which was like blood, did not shine all night long, although it was at the full
How does this relate to the day of Friday?
To begin with, because of the red moon described -]by Pilate/-] as being seen the night of the Lord’s death. The only kind of eclipse that can happen in a full moon phase is a lunar eclipse, frequently known to give the moon a “blood red” appearance, particularly when they are seen only partially. It so happens that there was such a partial lunar eclipse specifically on April 3 of the year 33 AD, according to
the work done by NASA.
Second, because when we look at the Jewish calendar, we find that Nissan 15, customary Passover day, would have fallen on a “Saturday”, April 4, 33. This would have made the Saturday a “high sabbath” - which is mentioned in the gospel (John 19:31-42) - which means that Friday, April 3 would have been the Day of Preparation in which the lamb sacrifice was killed, just hours before sunset (Exod. 12:6) - the exact time in which Christ was put to death on the Cross.
Typically, the Passover meal would have been eaten that Friday evening in 33 AD. However, the gospels tell us that Jesus ate the Passover with his disciples the night before – Thursday. Archaeology has given us the answer to this ancient conundrum not too long ago. In the Maccabean period, Essene solarists were joined by Pharisees and Sadducees, which led to the development of the lunisolar Mishmarot calendar, set out in fragments from Qumran. In the Passion week, their Passover was Thursday evening, April 2, 33 AD.
Faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth
