What was the moon phase on the night of the Last Supper?

Answer 1

The moon was full that night, because the Last Supper was a Passover Seder, which is why Catholics and many other Christian denominations use only unleavened bread for Communion.

Passover begins the night before 15 Nisan on the Hebrew calendar, and since every month of the Hebrew calendar begins at the time of the new moon, the 15th of every month is the time of the full moon.

Answer 2

The Last Supper is traditionally celebrated on Holy Thursday, which marks the beginning of the Christian celebration of Easter. The moon phase on Holy Thursday changes each year, so it would depend on the specific year of the Last Supper. It is not specifically documented in historical records which phase the moon was in on the night of the Last Supper.
