Halloween is a holiday celebrated on the night of October 31. The word Halloween is a shortening of All HallowsÃ¢â‚¬â„¢ Evening also known as Hallowe'en or All Hallows' Eve.
Traditional activities include trick-or-treating, bonfires, costume parties, visiting "haunted houses" and carving jack-o-lanterns. Irish and Scottish immigrants carried versions of the tradition to North America in the nineteenth century. Other western countries embraced the holiday in the late twentieth century including Ireland, the United States, Canada, Puerto Rico and the United Kingdom as well as of Australia and New Zealand.
The festival of Samhain is a celebration of the end of the harvest season in Gaelic culture. Samhain was a time used by the ancient pagans to take stock of supplies and prepare for winter. The ancient Gaels believed that on October 31, the boundaries between the worlds of the living and the dead overlapped and the deceased would come back to life and cause havoc such as sickness or damaged crops.
Trick-or-treating spread from the western United States eastward, stalled by sugar rationing that began in April 1942 during World War II and did not end until June 1947.
Early national attention to trick-or-treating was given in October 1947 issues of the children's magazines Jack and Jill and Children's Activities, and by Halloween episodes of the network radio programs The Baby Snooks Show in 1946 and The Jack Benny Show and The Adventures of Ozzie and Harriet in 1948. The custom had become firmly established in popular culture by 1952, when Walt Disney portrayed it in the cartoon Trick or Treat, Ozzie and Harriet were besieged by trick-or-treaters on an episode of their television show, and UNICEF first conducted a national campaign for children to raise funds for the charity while trick-or-treating.
