Matthew 26:1-5 (ESV)
When Jesus had finished all these sayings, he said to his disciples,  "You know that after two days the Passover is coming, and the Son of Man will be delivered up to be crucified."
 Then the chief priests and the elders of the people gathered in the palace of the high priest, whose name was Caiaphas,  and plotted together in order to arrest Jesus by stealth and kill him.  But they said, "Not during the feast, lest there be an uproar among the people."
“Not during the feast, lest there be an uproar among the people.“ Funny, jesus and God have different intentions than the elders and highpriest. And for all their plotting Jesus wins out.
There is significance to the fact that Jesus is killed during the Passover. He is our Passover lamb. After two days it is not just a feast that comes, but the Passover came, Jesus our Passover lamb slaughtered, the cross became the door post for all who believe, stained with the blood of the lamb we all eat in the sacrament of the altar, that death may pass us over.
Make all the plans you want, God will do what he wants.
