I know the answer cookie. Mark has him die the morning after the Passover meal. John has time the afternoon before the Passover meal. Rather than embrace truth and facts, you cling to having to believe inerrancy.
The biblical day starts at sundown.
1 In the beginning God created the heavens and the earth. 2 The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters.
3 Then God said, “Let there be light”; and there was light. 4 And God saw the light, that it was good; and God divided the light from the darkness. 5 God called the light Day, and the darkness He called Night. So the evening and the morning were the first day. Genesis 1:1-5
This causes some apparent contradictions, but most theologians point out that the 4 gospels are from different perspectives and complement each other, rather than act as parallel versions. If they were all the same, we'd only have 1 in scripture.
The concept of inerrancy is based upon two other important concepts, that scripture is inspired by God, and that God can't tell a lie or make a mistake.
There are many things in scripture that can't be reconciled physically and must be understood spiritually. However, in order to do so, you have to be spiritual.
10 But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. 11 For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God.
13 These things we also speak, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. 14 But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. 1 Corinthians 2:10-14
Anyone can read scripture, but not everyone is capable of understanding it.
The bible contains history, but it isn't a history book. It contains poetry, but it's not a poetry book. Scripture from Genesis to the book of the Revelation is all God's testimony of the person of His Son, our Lord Jesus Christ (and God's testimony about us, evil and sinful men in need of a savior.)
