That is some of the strangest reasoning I have seen in a long time...
Act 12:4 And when he had apprehended him, he put him in prison, and delivered him to four quaternions of soldiers to keep him; intending after Easter to bring him forth to the people.
The word Easter appears exactly once in the entirety of the KJV. Wonder why there is no command to keep Easter, or no scripture that show us that Easter replaces the Feasts of the Lord. The word that was translated here for Easter is...

2) the paschal lamb, i.e. the lamb the Israelites were accustomed to slay and eat on the fourteenth day of the month of Nisan (the first month of their year) in memory of the day on which their fathers, preparing to depart from Egypt, were bidden by God to slay and eat a lamb, and to sprinkle their door posts with its blood, that the destroying angel, seeing the blood, might pass over their dwellings; Christ crucified is likened to the slain paschal lamb

I could C&P it but you can look it up (it is somewhat long), Barclay recognizes it as the Passover and Days of Unleavened Bread.
From Bullingers...
Easter. Greek. to pascha, the Passover. Easter is a heathen term, derived from the Saxon goddess Eastre, the same as Astarte, the Syrian Venus, called Ashtoreth in the O.T.
From Albert Barnes...
Intending after Easter - There never was a more absurd or unhappy translation than this. The original is simply after the Passover ( μετὰ τὸ πάσχα meta to paschaThe word “Easter” now denotes the festival observed by many Christian churches in honor of the resurrection of the Saviour. But the original has no reference to that, nor is there the slightest evidence that any such festival was observed at the time when this book was written. The translation is not only unhappy, as it does not convey at all the meaning of the original, but because it may contribute to foster an opinion that such a festival was observed in the time of the apostles. The word “Easter” is of Saxon origin, and is supposed to be derived from “Eostre,” the goddess of Love, or the Venus of the North, in honor of whom a festival was celebrated by our pagan ancestors in the month of April (Webster). Since this festival coincided with the Passover of the Jews, and with the feast observed by Christians in honor of the resurrection of Christ, the name came to be used to denote the latter. In the old Anglo-Saxon service-books the term “Easter” is used frequently to translate the word “Passover.” In the translation by Wycliffe, the word “paske,” that is, “Passover,” is used. But Tyndale and Coverdale used the word “Easter,” and hence, it has very improperly crept into our King James Version.
John Gill matter of factly states...
intending after Easter,
or the passover,
It is a mistranslation of the word pascha. It should have been Passover.
