Halloween, or All Hallows' Eve, is a holiday that has become celebrated by people dressing up in costumes, carving pumpkins, and satisfying sugar cravings. In 2026, the National Retail Federation expects Americans to ring in the spookiest day of the year to the tune of a record $13.5 billion, most of it on candy and decorations. That's just part of an ongoing trend of upward growth: Halloween spending has nearly doubled over the past 15 years. Many celebrants will also shell out big bucks to dress up in the trending costumes of the year, like the K-pop stars from Netflix's 2025 hit "KPop Demon Hunters," or Elphaba and Glinda from the "Wicked" movies.
But long before Halloween became a time of donning costumes and eating candy, the holiday looked very different. The day represents the start of the new year for Wiccans, who believe it is the time of year when the boundaries between the real and supernatural worlds are thinnest. For this reason, Halloween is also believed to be the most potent time for fortune-telling and making significant prophecies about the future.
Halloween has undergone significant changes since its ancient Celtic origins in Ireland. The way people celebrate Halloween has shifted in response to technological advancements, urbanization, and changing attitudes toward celebrating a holiday as a community.
The origin of Halloween was religious, a day designated by the ancient Irish to celebrate and communicate with visiting spirits. It changed shape when the Catholic Church in an attempt to convert these people to its faith. Modern celebrations of Halloween have incorporated aspects of these and other traditions. It's now a day of lighting candles in pumpkins (and turnips) to keep ghosts away, but also perhaps gathering treats from decorated cars in a church parking lot and dressing up in costumes. A child would be more likely to mention a talking skeleton than a sacred bonfire when discussing the origin of Halloween.
