In response to the idea that Matthew 27:45; Mark 15:33 and Luke 23:14 are exaggerated accounts of a solar eclipse, Christian sources argue that the Passover always occurred during a full moon and that a solar eclipse cannot occur during a full moon. However, I can't find Scriptural evidence that the Passover had to occur during a full moon or astronomical evidence that a solar eclipse cannot occur during a full moon. Can you help?


The Passover was to be on the fourteenth day of the month (Lev. 23:5). Since Israel measured months on a lunar cycle, beginning each month with the new moon, the fourteenth of the month would always have been a full or near-full moon.

As far as the eclipse question goes, I'm no astronomer, but the point sounds correct to me. The lunar phases are observed as the moon travels around the earth (one lunar orbit takes about a month). We see only that portion of the moon that is directly facing the sun. When the moon is full, we see approximately the same portions of the moon's surface that we would see if we were standing on the sun, meaning that our perspective is very similar to the sun's. Thus, during a full moon, the moon is on the opposite side of the earth from the sun, and the earth is between the sun and the moon. This would seem to be the optimal positioning for a lunar eclipse, but an impossible positioning for a solar eclipse. During a solar eclipse, the moon must come between the earth and the sun, but this would seem to be possible only during a new moon.
