Why 31 October
Many sources trace the eve of All Saints’ Day (1 November) to 31 October—All Hallows’ Eve—later shortened to Halloween. Modern celebrations mix folklore, church calendar history and popular culture.
Trick-or-treat and costumes
Trick-or-treat, in which costumed children visit neighbors for candy, became widespread in 20th-century North America. Rules and hours are community decisions, not federal law.
Jack-o’-lanterns
Carved pumpkins with lights inside are a common decoration. Use battery tea lights instead of open flames near doorsteps and walkways.
