Hello Halloween!

"Halloween" at Wikipedia:

"Halloween is an observance celebrated on the night of October 31, usually by children dressing in costumes and going door-to-door collecting candy. It is celebrated in much of the Western world, though most common in the United States, Ireland, the United Kingdom, Canada and sometimes in Australia and New Zealand. 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" is derived from Hallowe'en, an old contraction, still retained in Scotland and some parts of Canada, of "All Hallow's Eve," so called as it is the day before All Saints day (observed by some Christians, including Roman Catholics), which used to be called "All Hallows," derived from All Hallowed Souls. In Ireland, the name was Hallow Eve and this name is still used by some older people. Halloween was formerly 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 reinterpretation. In Mexico, All Saint's Day, following Halloween, is the Day of the Dead.

Halloween is also called Pooky Night in some parts of Ireland, presumably named after the púca, a mischievous spirit.

In Britain and Ireland in particular, the pagan Celts celebrated the Day of the Dead on All Hallows Day (1st November). The spirits supposedly rose from the dead and, in order to attract them, food was left on the doors. To scare off the evil spirits, the Celts wore masks. When the Romans invaded Britain, they embellished the tradition with their own, which is the celebration of the harvest and honoring the dead. These traditions were then passed on to the United States and Canada.

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 spirit world can make contact with the natural world and when magic is most potent (see, for example, Catalan mythology about witches).

Anoka, Minnesota, USA, self-proclaimed "Halloween Capital of the World," celebrates with a large civic parade.

Salem, Massachusetts, USA, also has laid claim to the title "Halloween Capital of the World," though Salem has tried to seperate itself from its history in the subject of witchcraft. Despite that, the city does see a great deal of tourism surrounding the Salem witch trials, especially around Halloween."
