There are two practices of the roman catholic church, and one British that directly leads to this issue. First one of the first defining events of the divergence of the roman catholic church was the councils. If memory serves in the first council setting the date of the Passover by calculation from the roman calendar instead of the biblical counting of the abib (ripeness of the barley), which was shortly thereafter followed by the removal of the Jews from Judea to make the counting of the abib impossible. Second the practice of missionary adaption or declaring that all or part of the local unbiblical practices are actually biblical led to the Catholics declaring that the Rites of Estarti were actually Passover leading to confusion and the continuation of egg hunts. Third the British empire was not founded on procrastination, but on confidence and promptness. Unfortunately confidence and promptness are not always virtues for a translator, so since "everyone" knew Easter was the English word for Passover, no-one checked.

ps. check my spelling for the rites.
