Evolving from the ancient Celtic holiday of Samhain, modern Halloween has become less about literal ghosts and ghouls and more about costumes and candy. The Celts used the day to mark the end of the harvest season and the beginning of winter and also believed that this transition between the seasons was a bridge to the world of the dead. Over the millennia the holiday transitioned from a somber pagan ritual to a day of merriment, costumes, parades and sweet treats for children and adults.

Like each festivity has some uncanny facts about it. Halloween too has many:

• The first Jack O’Lanterns were actually made from turnips.
• The word “witch” comes from the Old English wicce, meaning “wise woman.” In fact, Wiccan were highly respected people at one time. According to popular belief, witches held one of their two main meetings, or sabbats, on Halloween night.
• Samhainophobia is the fear of Halloween.
• Fifty percent of kids prefer to receive chocolate candy for Halloween, compared with 24% who prefer non-chocolate candy and 10% who preferred gum.
• The owl is a popular Halloween image. In Medieval Europe, owls were thought to be witches and to hear an owl's call meant someone was about to die.
• According to Irish legend, Jack O’Lanterns are named after a stingy man named Jack who, because he tricked the devil several times, was forbidden entrance into both heaven and hell. He was condemned to wander the Earth, waving his lantern to lead them away.
• Trick-or-treating evolved from the ancient Celtic tradition of putting out treats and food to placate spirits who roamed the streets at Samhain, a sacred festival that marked the end of the Celtic calendar year.
• “Souling” is a medieval Christian precursor to modern-day trick-or-treating. On Hallowmas (November 1), the poor would go door-to-door offering prayers for the dead in exchange for soul cakes.
• The first known mention of trick-or-treating in print in North America occurred in 1927 in Blackie, Alberta, Canada.
• Black and orange are typically associated with Halloween. Orange is a symbol of strength and endurance and, along with brown and gold, stands for the harvest and autumn. Black is typically a symbol of death and darkness and acts as a reminder that Halloween once was a festival that marked the boundaries between life and death.
• Ireland is typically believed to be the birthplace of Halloween.
• Scarecrows, a popular Halloween fixture, symbolize the ancient agricultural roots of the holiday.
• Halloween has variously been called All Hallows’ Eve, Witches Night, Lamswool, Snap-Apple Night, Samhaim, and Summer’s End.
• Halloween was influenced by the ancient Roman festival Pomona, which celebrated the harvest goddess of the same name. Many Halloween customs and games that feature apples and nuts date from this time. In fact, in the past, Halloween has been called San-Apple Night and Nutcrack Night.
• Children are more than twice as likely to be killed in a pedestrian/car accident on Halloween than on any other night
• The Village Halloween parade in New York City is the largest Halloween parade in the United States. The parade includes 50,000 participants and draws over 2 million spectators
