Some Christians beleive Easter is a Christian Holy Day. Others do not. What the apostle Paul says about this is practical....
Col. 2
Freedom From Human Rules
16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. 17 These are a shadow of the things that were to come; the reality, however, is found in Christ. 18 Do not let anyone who delights in false humility and the worship of angels disqualify you. Such a person also goes into great detail about what they have seen; they are puffed up with idle notions by their unspiritual mind. 19 They have lost connection with the head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.
20 Since you died with Christ to the elemental spiritual forces of this world, why, as though you still belonged to the world, do you submit to its rules: 21 “Do not handle! Do not taste! Do not touch!”? 22 These rules, which have to do with things that are all destined to perish with use, are based on merely human commands and teachings. 23 Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and their harsh treatment of the body, but they lack any value in restraining sensual indulgence.
Col 2:20 Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations—
The biblical holy days of the Lord are not basic priniciples of the "World". They are the days commanded by the Lord in sacred scripture.
Col 2:21 "Do not touch, do not taste, do not handle,"
Col 2:22 which all concern things which perish with the using—according to the commandments and doctrines of men?
The biblical holy days of Jesus Christ are not "commandments and doctrines of men" but are holy days created and instituted by Jesus Christ.
The view you're repeating of Colossians 2 is an old one that attempts to justify not observing the Lords' holy days.
Paul was not speaking about “easter.” it took two centuries after Paul’s time for the easter abomination to defile Christian worship.
In verses 20-23 he was speaking of the false Torah of the Pharisees, which laid nonsensical restrictions on peoples behavior that were unscriptural. the spirit of that false oral torah later became the “catholic church.”
