No. Easter, which means the celebration of the resurrection, was put into Acts 12:4 by design. The Translators knowing that in Acts the believers would be celebrating the Christian Pascha, and not the Jewish Pascha, which historically was in the same week until the middle ages. Before Acts, the Jewish Passover was celebrated, and translated that way because Jesus had not yet died as the Passover Lamb of God. After his death they no longer celebrated the Old shadow Passover (Greek - Pascha) by killing a lamb, but they practiced the new resurrection celebration of Easter (also Greek - Pascha).
