> The short answer is “no”. Contrary to Seth Andrews’ claims about “the Catholic Church” stealing a pagan festival “involving the druid priests and the people dressing up in masks and tricks and treats”, the date and most of the traditions are firmly Christian in origin. The November 1 date that is the centre of “Allhallowmas” was not derived from any “Celtic” original and the original Irish date for an All Saints feast moved from April 20 to November 1 due to the influence of Continental and English liturgical practice. That this meant the new All Saints Day fell on the “quarter day” of Samhain was pure coincidence. Contrary to repeated insistence in popular sources, scholars can find no clear indication of any ritual or religious practices on Samhain, and certainly none that can be traced to later Halloween traditions. Masks, costumes, trick or treating, Halloween games etc. all either have known traditional Christian origins or simply cannot be linked to anything definitely pre-Christian.
