I invite you to read Leviticus 23. Here, God instructs us as to the holidays we should celebrate. Also, Exodus 12 describes the Passover, which is what we should be celebrating instead of Easter.
I would also invite you to read about the prophetic nature of Lev 23. This site does a good job, and there are many others: http://waitingforjesus.com/jewishfeastsprophecy.html
"Our Easter celebratory rituals, BTW, were mostly adapted from pagan spring fertility rites."
More like we have allowed pagan rituals which have nothing to do with the Bible to replace our celebration of the Passover, and distract us from God.
That is a book of the Old Testament, and none of the "festivals" (with the exception of Passover) resembles *any* holiday I've ever heard of. Even Passover is not celebrated the way it is described there. Plus, a lot of those "festivals" seem to require sacrifices of live animals, which is not a feature of Christianity, nor, as far as I am aware, is it a feature of modern Judaism.
Within the New Testament, I do not recall ever seeing that we are commanded to celebrate certain events, much less any instruction on how we should celebrate them. If we are to use Leviticus as a guide, we should not celebrate *any* Christian events--not Christmas, not Easter, no Saint's days (e.g. Saint Valentine, Saint Patrick)--or any of the other, not as publicized, Christian holidays that are on the calendar.

I do not know about "we have allowed", considering that none of us were alive in the early days of Christianity. When early evangelical Christians went out to convert people (as commanded by the Bible), they observed that the people they were trying to convert already had religions and associated rituals. So, to sell those people on the idea of Christianity, they simply co-opted the existing seasonal celebrations, gave them a Christian spin, and thus offered the people salvation through Christ without requiring them to give up their pre-existing rituals.
As the old saying goes, "God works in mysterious ways." And if God inspired early Christians to co-opt pagan rituals into the service of promoting Christianity, who am I to question?
So how was “The Feast of Shelters” this year? What was on the menu?
