***and He arose from the tomb on Saturday (the 17th)....early before sunrise. ****
Luk 24:20 And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him.
Luk 24:21 But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.
Because they were traveling from Jerusalem toward Emmaus, this had to be SUNDAY, and this WAS THE THIRD DAY.
I use this calender. As you can see, Nisan 14 fell on FRIDAY, not Wednesday. Further more, only AD 30 or 33 fits. You will have to wait till AD 34 to get a Wednesday crucifiction
Here is the problem with your calendar:
It shows Nisan 14 falling on a Friday. Whoop de doo! Why do you suppose Mr. Fotheringham used that date?
The Vernal Equinox (in the year 30 A.D.) fell on March 23rd at 12:49 A.M. Jerusalem time.
Season Calendar for Jerusalem
Coincidentally, the new moon also fell on the same day....which was a Thursday. If (as your calendar shows) the 14th was Friday....then the new moon would have been on a Saturday.
30 A.D. is known for the fact that the New Moon and the Equinox occurred on the same day. This happens about four times every 59 years.....so it's somewhat unusual.
It does not take a degree in mathematics to then count to 14 (including Thursday as day #1)...... to arrive at Passover, Wednesday the 14th, 30 A.D.
Since you don't know..... I'll explain something to you. Mr. Fotheringham was a charlatan.....doing nothing more than forcing his conclusions to fit the Main Stream narrative.
