the "last supper" was not Passover, because when Yahdah the betrayer (Judah Iscariot) went to betray the disciples thought Yahshua sent him to get the things for Passover. Why would they think he was going to get the things for the meal they just finished eating?
And the Passover day is a preperation day, most "high Sabbths" or "Feast Days" are no work days, just worship Yah, but the Passover is a preperation and when the sun goes down on it Feast of Unleavened starts and that is when one eats the meal.
Messiah was killed right when the Passover lambs were being killed, for He is the real Passover Lamb.
Pretty close my friend preparation day (correct me with scripture and my previous post if I am incorrect) was actually the 14th, and Passover was the beginning of the 15th day accordingly, reading Exodus 12. Passover was at night, the darkness that followed the killing of the lamb.
