Halloween is the second-largest commercial holiday in the United States after Christmas, with over $10 billion spent annually on costumes, candy, decorations, and events. It is celebrated by people of all ages, from toddlers in adorable costumes to adults at elaborate costume parties.
About Halloween
Halloween originated from the ancient Celtic festival of Samhain (pronounced "sow-in"), celebrated on November 1st to mark the end of harvest and the beginning of the dark half of the year. The Celts believed that on the night before Samhain, the boundary between the living and the dead became blurred, allowing spirits to roam the earth.
When Irish and Scottish immigrants came to America in the 19th century, they brought their Halloween traditions. Jack-o'-lanterns were originally carved from turnips and potatoes in Ireland; pumpkins became the medium of choice in America because they were larger and easier to carve. The legend of "Stingy Jack," a man who tricked the Devil and was doomed to wander the earth with only a carved-out turnip to light his way, gave the tradition its name.
Modern Halloween has expanded into a massive cultural event. Over 600 million pounds of candy are purchased for trick-or-treaters each year. Haunted attractions generate over $300 million annually. Costume trends reflect pop culture, with movie characters, memes, and celebrity looks dominating each year. And the tradition of carving pumpkins has become an art form, with competitive pumpkin carving events drawing thousands of spectators.

What are the origins of trick-or-treating?
Trick-or-treating has roots in the medieval practice of 'souling,' where poor people would go door-to-door on All Souls' Day offering prayers for the dead in exchange for food called 'soul cakes.' The modern version emerged in North America in the 1920s and 1930s, becoming widespread by the 1950s. The phrase 'trick or treat' implies a playful threat of mischief if treats are not given.
