Easter Catholic year round

There are three Christian Paschs (St. Francis de Sales). First, Christmas, where the Christ Child was spared Herod's attempt to kill him; so He, Jesus Christ, could bring us salvation. Second, the Cross (see below, The meaning of the Pasch of Christians) and third, the Resurrection of Christ where death was conquered once for all.

The meaning of the Pasch of Christians. 

The Book of Wisdom, Chapter 17, describes the devils and demons thrown back upon the Egyptians when the Israelites under Moses were brought out of Egypt by God for God’s purposes (to prepare a place for the Crucifixion of Our Lord for the Redemption of the whole world of those who are saved). In the same way the same false gods and goddesses that the Egyptians served and which in so doing were the reason the Egyptians sacrificed their sons and daughters to the devils and demons behind the false gods/goddesses were the spirits that killed the Egyptian children that perished when the Israelites were brought out of Egypt. God does not murder children, period. The angel of death which destroyed in Egypt was one of the fallen spirits. God did not cause any of the fallen spirits to hurt anyone. God allowed the fallen spirits to do what it is their nature do to when He brought the Israelites out of the gates of hell which was Egypt. The children below the age of reason that died went to be with God for eternity, they will be resurrected with the just at the Second Coming of Christ. This principle of God allowing the innocent to be afflicted along with guilty finds its ultimate fulfillment in Christ’s singular and only salvific Kenosis. Jesus Christ committed no sin, not ever nor could He, and was and is and only could be utterly and absolutely and completely innocent of any and all wrongdoing and sin by His very nature as the Holy and True God. The guiltless sacrificed by His own will for the guilty. Even when the innocent are afflicted by the actions and evils instigated by the fallen spirits in the world, the innocent are not possessed by those fallen spirits. The principle of all being afflicted by the evil set loose upon the world for its unrepentant sin will occur when the universal plagues are let loose upon the world.

Christmas and Easter are absolutely and completely joined and linked and in Essence of the Nature of the Godhead that Christ possesses from eternity to eternity: One. Salvifically they are linked where man is concerned by Christ's Kenosis. All of God's works are known to Him from eternity from before all of creation (time is only an aspect of creation) unto the endless ages of ages to come (eternity in the recreated universe at Christ's Second Coming).

Of this St. Paul speaks:

Colossians

1:15 Who is the image of God, the invisible one, the firstborn over all creation.

Firstborn means, first of all, Christ the Son of God Who is the image of the invisible God engendered of God the Father from before all time and creation. Secondly, it means the Incarnation of Christ nine months before and His birth from a virgin on Christmas. Christ is the Second Person of the Godhead and once Incarnate He is Incarnate forevermore, for eternity. As the Son of Man, that is Second Person of the Godhead, and therefore God, Incarnate, He is also the Firstborn in His Incarnation and birth, see Matthew 1:25, Luke 2:7 below. Thirdly it means the eternal meaning of the first two meanings in their final eschatological and salvific union of Christ the Firstborn from the dead at His Resurrection. As the Incarnate God, Christ's Kenosis, most especially on His Cross, is the ONLY salvation for fallen man that there ever was or could be. There is no other. 

Matthew 1:25

And he knew her not till she brought forth her firstborn son: and he called his name JESUS.

Luke 2:7

And she brought forth her firstborn son, and wrapped him up in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.

The Sovereign Lord Jesus Christ explains the same thing here, as the image of the invisible God the Father, to see God the Son Jesus Christ is to see the Incarnate God, no longer invisible but now visible, and Who is the Firstborn from before all of creation and the Firstborn of all men ever Who lived at His Immaculate Conception and virgin Birth and the Firstborn from the dead of all men at His Resurrection, all men who all will be raised by Christ (at the General Resurrection):

John 14: 6 Jesus saith to him: I am the way, and the truth, and the life. No man cometh to the Father, but by me. 7 If you had known me, you would without doubt have known my Father also: and from henceforth you shall know him, and you have seen him. 8 Philip saith to him: Lord, shew us the Father, and it is enough for us. 9 Jesus saith to him: Have I been so long a time with you; and have you not known me? Philip, he that seeth me seeth the Father also. How sayest thou, shew us the Father? 10 Do you not believe, that I am in the Father, and the Father in me? The words that I speak to you, I speak not of myself. But the Father who abideth in me, he doth the works. 

"...the Father who abideth in me, he doth the works." includes the Resurrection of Christ and the future resurrection of all men raised by Christ at His Second Coming. 

1:16 That in him all things were created, in the heavens and on the earth.The visible and invisible, whether thrones, dominions, powers, or authorities; all things have been created through him and for him.
1:17 Indeed he is before all things, and in him all things have been held together;

Third meaning of Firstborn is below in verse 1:18, i.e. the Resurrection of Christ, which guarantees the resurrection of all men that ever lived.

1:18 and he is the head of the body, the church; who is the beginning, the firstborn of the dead; so that in all things he may come [the Second Coming of Christ as well as His procession from the Father are both included here] having first place.

1:19 Because in him all the fullness of God was pleased to dwell
[St. John uses, full, fullness, Greek "pleroma" - the same meaning and word in the Gospel of John 1:14 and 1:16. Christ has the whole fullness of the Godhead and bestows His gifts therefrom.]
1:20 and through him to reconcile completely all things into himself, making peace through the blood of his cross, through him, indeed the things on the earth, and also the things in the heavens. [the Kenosis of Christ is emphatically referred to here.]
