The Passover Story in the Book of Revelation

In matthew 26, when jesus had finished saying all these things, he says to his dis ples, passover is two days away. In john 12, 12, the next ay, the great crowd that had come for the feast heard that jesus was on his way to jerusalem. They took palm branches and went out to meet him. So we talk about two separate stories, or the same storys back on of matthew 26. See if there's any wiggle room in the time line over here.
