Like Christmas, Easter is celebrated at different times then the original event. But? We celebrate the Christ, the world does their thing. So? Let the world have their Winter break and Spring break, But we shall celebrate the true meanings. Jesus does not need one day, he wants all of our days. As Paul wrote:
Gal 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage?
Gal 4:10 Ye observe days, and months, and times, and years.
Gal 4:11 I am afraid of you, lest I have bestowed upon you labour in vain.
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
