Halloween literally means “hallowed (holy) evening” and comes from “All Hallows’ Eve,” the night before the Christian feast of All Saints’ Day on November 1. Today it’s mostly a secular celebration of spooky fun, costumes, and candy, but it grew out of much older Celtic and Christian traditions.

Basic meaning of Halloween

  • The word “Halloween” is a contraction of “All Hallows’ Eve,” the evening before All Hallows’ (All Saints’) Day.
  • In modern use, it is a holiday on October 31 known for costumes, trick-or-treating, and eerie or playful themes.

Ancient roots

  • Many historians link Halloween’s origins to the ancient Celtic festival of Samhain, marking the end of harvest and the start of the dark half of the year.
  • During Samhain, people believed the boundary between the living and the dead was thin, so they lit bonfires and wore disguises to ward off spirits.

Christian layer: All Hallows’ Eve

  • As Christianity spread in Europe, the church placed All Saints’ Day on November 1, and the evening before became “All Hallows’ Eve,” later “Halloween.”
  • This period, called Allhallowtide, includes All Hallows’ Eve, All Saints’ Day, and All Souls’ Day, focused on remembering the dead.

What Halloween means today

  • In much of Europe and North America, Halloween is now largely nonreligious: people carve pumpkins, wear costumes, attend parties, and children go trick-or-treating.
  • For many, it means a night to enjoy spooky stories, horror movies, and playful scares rather than a serious spiritual observance.

Different viewpoints

  • Some see Halloween as cultural fun with community-building: decorating homes, giving out candy, and enjoying creativity in costumes.
  • Others, especially in some religious communities, focus more on or critique its pagan roots, preferring to emphasize All Saints’ Day or alternative fall festivals.

TL;DR: “What does Halloween mean?” At its core: “holy evening” before All Saints’ Day, built on older Celtic ideas about the dead, now transformed into a mostly secular night of costumes, candy, and spooky fun.
