The preparation day for the Sabbath is commanded just as surely as the Sabbath is. It does not have the same weight, as it were, because it is not part of "the big Ten" but it is certainly a valid attachment to the fourth commandment.
This is a particularly tricky concept for us, living in this time because it is possible for us to justify doing things on the Sabbath on the grounds that it is so easy now. Technology has come up with all kinds of automatic equipment to do things. We can flip a switch, and the machine is not "working." But what did God have in mind? Just remember that the Sabbath is the test Commandment! The test is to show whether we live by faith, that is, whether we believe God's Word.
God knows the end from the beginning, does He not? He surely knew that men would develop machines to cook and preserve food. Why did He establish the preparation principle? The issue is not merely the labor or the muscular energy expended. It is "the whole package" that God is concerned about. The bigger question is, "Why are we doing this?" What is our motivation and what purpose is being accomplished?
Why do we need this kind of training? God wants to train us so that we do not make bad judgments. He is preparing kings and priests for His Family (Revelation 5:10) for the WorldTomorrow. Are we not prepared when Sabbath comes around because we have managed our week badly? Are we unprepared for the Sabbath because we are involved in things the other six days—and maybe especially on the preparation day—so that preparation is impossible? What kind of adjustments do we need to make?
It might be good to remember that the preparation day begins on Thursday night (as we look at it today), and it can provide time to prepare. God's intent is that we keep the Sabbath free from distractions that keep us from properly using it. The primary use of the day is to fellowship with Him.

The Fourth Commandment (Part 5)
Also there is a preparation Day for Passover (In fact ANY Holy Day is a "Sabbath", but there Passover is Really important
All four gospel writers mention that Jesus was tried, convicted, crucified, and buried on a preparation day. Without any further clarification, one would assume that they meant a Friday, the weekly preparation day before the Sabbath. But can other days be considered preparation days as well?
Yes, indeed! God Himself gave the instructions about the use of the preparation day to the Israelites before they reached Mount Sinai (Exodus 16:23). The Jews later considered this to be so important that they made sure each of the holy days, which are also Sabbaths, was preceded by a preparation day. Since the holy days can fall on any day of the week, the preparation day can fall on any day of the week as well.
This is very relevant to the Passover. Not only is the Passover a festival in its own right, it also functions as the preparation day for a holy day, the first day of the Feast of Unleavened Bread. According to the calculated Hebrew Calendar, Passover can fall on a Monday, Wednesday, Friday, or Sabbath.
Clearly, our Savior was crucified on THE JEWISH Passover day (Matthew 26:2)...(Not God's Passover Day, which Jesus observed a Day earlier as the Jewish Calendar is not God's Calendar!) Thus, it was on one of these days of the week that Jesus was killed and buried.
