What’s the Origin of Halloween, Why Do We Celebrate It on October 31?

What Does Halloween Mean?

The current English name Halloween traces back to medieval Christianity. The word hallow is derived from the Middle and Old English words for holy. As a noun, it can also mean saint. In those days, the Christian holiday we know as All Saints’ Day was called All Hallows’ Day, and the day before, when an evening mass was held, was All Hallows’ Eve. That three-word name eventually got shortened to Halloween.

Why Do We Celebrate Halloween on October 31?

The path to the Christian Halloween date of October 31 is a little more complex. Pope Boniface IV began All Saints Day in the early 7th century when he dedicated the Pantheon in Rome to the saints, but the day was May 13. In the next century, Pope Gregory III changed the day to November 1 when he dedicated a chapel in St. Peter’s Basilica to the saints. Yet another century later, Pope Gregory IV added All Saints Day to the Christian calendar, extending the celebration from Rome to churches everywhere. With All Saints Day came All Hallows’ Eve on October 31. This was, perhaps, an effort to offset the pagan occasion with a religious celebration.

The History of Halloween Activities

The mystical rituals of earlier times evolved into more lighthearted fun and games. For example, the somewhat heavy concept of connecting to the dead was replaced with the more lighthearted idea of telling the future. Bobbing for apples, for example, became popular as a fortune-telling game on All Hallows’ Eve: Apples would be selected to represent all of a woman’s suitors, and the guy—er, apple—she ended up biting into would supposedly represent her future husband. In fact, Halloween previously posed a huge (albeit rather superstitious) matchmaking opportunity for young women in the 19th century.

Another popular All Hallows’ Eve ritual was mirror-gazing, as people hoped to catch a vision of their future by looking into the mirror. There are also reports of fortune-cookie-like favors being given out during earlier times. People wrote messages on pieces of paper in milk, and the notes were then folded and placed into walnut shells. The shells would be heated over a fire, causing the milk to brown just enough for the message to mystically appear on the paper for the recipient.

Many people were said to dress up as saints and recite songs or verses door to door. Children would also go door to door asking for “soul cakes,” a treat similar to biscuits. Technical note: Soul cakes originated as part of the All Souls’ Day holiday on November 2 (yep, a third holiday following Halloween and All Saints’ Day!) but eventually became a part of Halloween night as the concept evolved into trick-or-treating. The candy-grabbing concept also became mainstream in the U.S. in the early to mid-1900s, during which families would provide treats to children in hopes that they would be immune to any holiday pranks.

As for the costumes, they evolved, too. While they began as earnest tributes to saints, that tradition likely fell out of favor at some point… until young Scottish and Irish pranksters got the idea to dress up in scary-looking garb again as a way to spook unsuspecting neighbors. And just like that, thanks to these local hooligans, Halloween costumes became scary, spooky, funny, and creative all at the same time.

How Halloween Is Celebrated Today

Halloween obviously remains a popular holiday in America today, but it actually almost didn’t make it across the Atlantic. The Puritans were disapproving of the holiday’s pagan roots, so they didn’t take part. The American colonial Halloween celebrations that did take place featured large public parties to commemorate the upcoming harvest, tell ghost stories, sing, and dance. However, the holiday only took hold as part of the national zeitgeist in the second half of the 19th century as Irish and Scottish immigrants began to arrive in America in greater numbers.
