I would still like to hear from anyone about this.
Halloween (IPA pronunciation: [hælə'win], [hælo'win]) is an observance celebrated on the night of October 31, most notably by children dressing in costumes and going door-to-door collecting sweets. It is celebrated in much of the Western world, though most common in Canada, the United States, Puerto Rico, Ireland, the United Kingdom, and with increasing popularity in Australia and New Zealand. Halloween originated in Ireland as the pagan Celtic harvest festival, Samhain. Irish, Scots and other immigrants brought older versions of the tradition to North America in the 19th century. Most other Western countries have embraced Halloween as a part of American pop culture in the late 20th century.
The term Halloween, and its older spelling Hallowe'en, is shortened from All-hallow-even, as it is the evening before "All Hallows' Day" (also known as "All Saints' Day"). In Ireland, the name was All Hallows' Eve (often shortened to Hallow Eve), and though seldomly used today, it is still a well accepted label. Halloween was also sometimes called All Saints' Eve. The holiday was a day of religious festivities in various northern European pagan traditions, until it was appropriated by Christian missionaries and given a Christian interpretation. Halloween is also called Pooky Night in some parts of Ireland, presumably named after the púca, a mischievous spirit.
Halloween is sometimes associated with the occult. Many European cultural traditions hold that Halloween is one of the liminal times of the year when the spiritual world can make contact with the physical world and when magic is most potent (e.g. Catalan mythology about witches).
