halloween has roots in a celtic festival called what
Halloween It is widely believed that many Halloween traditions originated from ancient Celtic harvest festivals, particularly the Gaelic festival Samhain; that such festivals may have had pagan roots; and that Samhain itself was Christianized as Halloween by the early Church.[1][7][12][13][14][15] Some believe, however, that Halloween began solely as a Christian holiday, separate from ancient festivals like Samhain.[1][16][17][18][19]
