Jamieson-Fausset-Brown Bible Commentary
10. To regard the observance of certain days as in itself meritorious as a work, is alien to the free spirit of Christianity. This is not incompatible with observing the Sabbath or the Christian Lord's day as obligatory, though not as a work (which was the Jewish and Gentile error in the observance of days), but as a holy mean appointed by the Lord for attaining the great end, holiness. The whole life alike belongs to the Lord in the Gospel view, just as the whole world, and not the Jews only, belong to Him. But as in Paradise, so now one portion of time is needed wherein to draw off the soul more entirely from secular business to God (Col 2:16). "Sabbaths, new moons, and set feasts" (1Ch 23:31; 2Ch 31:3), answer to "days, months, times." "Months," however, may refer to the first and seventh months, which were sacred on account of the number of feasts in them.
times-Greek, "seasons," namely, those of the three great feasts, the Passover, Pentecost, and Tabernacles.
years-The sabbatical year was about the time of writing this Epistle, A.D. 48 [Bengel].

"You observe days, and months, and times and years."
At face value does this say…Pentecost, Days of Unleavened Bread, Feast of Tabernacles, and such? Be honest! Of course it does not. Then are we to assume without proof that God's holy days are being called into question and abrogated? That would be a dangerous assumption which could put one in the category Peter spoke of - twisting Scripture unto our own destruction. We need to ask some questions and search out the answers.
WHO WERE GALATIANS?
Paul wrote to Galatians. But who were they? They were Gentile converts and had come from a background of pagan practices. Let's not be afraid to look into their background. Galatia was a region in Asia Minor where the churches of Lystra, Iconium, Antioch, Derbe and others were located. Now let's look in Acts 14:8-18 for their background. Paul was used by Christ to heal a man born in a crippled condition. See verses 8 - 10. As a result the pagan Gentiles wanted to worship Paul and Barnabas thinking the apostles were their gods, Jupiter and Mercury! They even wanted to do sacrifice to them v.11-13. Paul and Barnabas, pleading with them to not do such a thing scarcely restrained them v. 14-18.
This is precisely what Paul said to them in Gal. 4:8 as to how they were prior to conversion.
"Howbeit then, when you knew not God, you did service unto them which by nature are no gods."
They had been slaves to gods that were not even gods at all. They had been worshipping demons. It was out of this pagan superstition that Christ used Paul and Barnabas to convert them into serving the living Christ.
Now someone was trying to beguile them into returning to their former ways. Paul was alarmed! Gal. 4:9…
"But now, after that you have known God, or rather are known of God, HOW TURN YOU AGAIN (back) to the weak and beggarly elements, whereunto you desire again to be in bondage?"
What were those ways they were turning back to? "Observing days, months, times and years." They could NOT be returning to God's festivals! As Gentiles, they had never kept them before Paul preached about them.
WAYS OF PAGAN WORSHIP
The heathen followed certain customs of observing particular days. Go to a reputable encyclopedia and you will find various festivals of the heathen. Saturnalia - today called Christmas; feast of Astarte with special cakes made to this 'queen of heaven' - today is Easter and hot cross buns; All Saints Day or Hallowe'en today; and women weeping for Tammuz - Lent, today.
Galatians 4:9-10: Are God's Laws Bondage?
Some view Galatians 4:9-10 as condemning Old Testament laws. In these verses Paul wrote: "But now after you have known God, or rather are known by God, how is it that you turn again to the weak and beggarly elements, to which you desire again to be in bondage? You observe days and months and seasons and years."
Those who argue against God's laws see Paul's reference to "days and months and seasons and years" as pointing to the Sabbath, festivals and sabbatical and jubilee years given in the Old Testament (Leviticus 23, 25). They view these God-given observances as the "weak and miserable principles" (NIV) to which the Galatians were "turn[ing] again" and becoming "in bondage" (verse 9).
Is this Paul's meaning?
There is an obvious problem with viewing these verses as being critical of the Sabbath, since the Sabbath is not even mentioned here. The term "Sabbath," "Sabbaths" and any related words do not even appear anywhere in the epistle to the Galatians.
To argue against keeping the Sabbath, some assume that the "years" referred to in Galatians 4:10 are the sabbatical and jubilee years described in Leviticus 25. However, the jubilee year was not being observed anywhere in Paul's day, and the sabbatical year was not being observed in areas outside Palestine (Encyclopaedia Judaica, Vol. 14, p. 582, and Jewish Encyclopedia, p. 666, "Sabbatical Year and Jubilee"). The fact that Galatia was in pagan Asia Minor, far outside the land of Israel, makes it illogical to imagine Paul could have been referring to the sabbatical and jubilee years.
The Greek words Paul used for "days and months and seasons and years" are used throughout the New Testament in describing normal, civil periods of time. They are totally different from the precise terms Paul used in Colossians 2:16 specifying the Sabbaths and festivals of God. He used exact terminology for biblical observances in Colossians, but used very different Greek words in Galatians—a clear indication that he was discussing altogether different subjects.
To understand what Paul meant, we must examine both the historic and immediate contexts of these verses.
The Galatians couldn't "turn again" to days they had never observed
The Galatian churches were composed mostly of members from a gentile, rather than Jewish, background. Paul made it clear that they were physically uncircumcised (Galatians 5:2; 6:12-13), so they could not have been Jewish.
This background is important in understanding this controversial scripture. In Galatians 4:9-10, Paul said that the Galatians were "turn[ing] again to the weak and beggarly elements," which included "days and months and seasons and years." Since Paul's readers were from a gentile background, it is difficult to see how the "days and months and seasons and years" they were turning back to could be the Sabbath and other biblical festivals, since they could not "turn again" to something they had not previously observed.
This is made even clearer by the immediate context. In verse 8, Paul said, "When you did not know God, you served those which by nature are not gods." By this Paul referred "clearly to the idols of paganism, which, in typical Jewish idiom, Paul termed 'not gods'" (The Expositor's Bible Commentary, 1976, Vol. 10, p. 475).
Not referring to biblical practices
Is it possible that these "weak and beggarly elements" they were returning to (verse 9) could be God's laws, Sabbaths and festivals? The word translated "elements" here is the Greek word stoicheia. What does it mean? The Expositor's Bible Commentary explains:
"It would seem that in Paul's time . . . stoicheia . . . referred to the sun, moon, stars, and planets—all of them associated with gods or goddesses and, because they regulated the progression of the calendar, also associated with the great pagan festivals honoring the gods. In Paul's view these gods were demons. Hence, he would be thinking of a demonic bondage in which the Galatians had indeed been held prior to the proclamation of the gospel . . .
"In the verses that follow, Paul goes on to speak of these three crucial subjects in quick succession: (1) 'those who by nature are not gods,' presumably false gods or demons; (2) 'those weak and miserable principles,' again stoicheia; and (3) 'days and months and seasons and years' (vv. 9, 10). No doubt Paul would think of these demons in ways entirely different from the former thinking of the Galatians . . . Thus, this whole issue takes on a cosmic and spiritual significance. The ultimate contrast to freedom in Christ is bondage to Satan and the evil spirits" (p. 472).
Superstitious observance of days and times
This is the context in which at least some of the Galatians were observing special "days and months and seasons and years." The word translated here as "observe" or "observing" is the Greek word paratereo, meaning "to watch closely, [or] observe narrowly" (W.E. Vine, Vine's Complete Expository Dictionary of Old and New Testament Words, 1985, "Observation, Observe").
This word "seems to have the sense of 'anxious, scrupulous, well-informed observance in one's interest,' which . . . fit[s] regard for points or spans of time which are evaluated positively or negatively from the standpoint of the calendar or astrology" (Gerhard Kittel, Theological Dictionary of the New Testament, 1995, Vol. 8, p. 148).
Whatever "days and months and seasons and years" the Galatians were observing, they were apparently observing them in a superstitious manner, as they had observed days and times before their conversion.
From the context, we see it is simply not logical to conclude that Paul was criticizing the observance of the biblical Sabbath and festivals, since they were not even mentioned anywhere in this epistle. Instead, he was attacking misguided efforts to attain salvation through unnecessary superstitious observances.
Paul tells them, "I am afraid for you, lest I have labored for you in vain" (verse 11). He was trying to prevent them from again becoming entangled in their former pagan practices.
