Pre-dating Christianity, the Celtic holiday was celebrated on the one night between autumn and winter when the barrier between living and dead was thinnest and often involved rituals that included human sacrifice.
Eldri en kristindķmur, var ūessi hátíđ Kelta haldin nķttina milli hausts og vetrar ūegar ūynnst voru skilin milli lifenda og dauđra og oft kröfđust helgisiđir mannblķta.
