Halloween or Hallowe'en (a contraction of "All Hallows' evening"),[5] also known as Allhalloween

Neopaganism
There is no consistent rule or view on Halloween amongst those who describe themselves as Neopagans or Wiccans. Some Neopagans do not observe Halloween, but instead observe Samhain on 1 November,^[258] some neopagans do enjoy Halloween festivities, stating that one can observe both "the solemnity of Samhain in addition to the fun of Halloween". Some neopagans are opposed to the celebration of Hallowe'en, stating that it "trivializes Samhain",^[259] and "avoid Halloween, because of the interruptions from trick or treaters".^[260] The Manitoban writes that "Wiccans don't officially celebrate Halloween, despite the fact that 31 Oct. will still have a star beside it in any good Wiccan's day planner. Starting at sundown, Wiccans celebrate a holiday known as Samhain. Samhain actually comes from old Celtic traditions and is not exclusive to Neopagan religions like Wicca. While the traditions of this holiday originate in Celtic countries, modern day Wiccans don't try to historically replicate Samhain celebrations. Some traditional Samhain rituals are still practised, but at its core, the period is treated as a time to celebrate darkness and the dead – a possible reason why Samhain can be confused with Halloween celebrations."^[258]

The traditions and importance of Halloween vary greatly among countries that observe it. In Scotland and Ireland, traditional Halloween customs include children dressing up in costume going "guising", holding parties, while other practices in Ireland include lighting bonfires, and having firework displays.^{[151][261][262]} In Brittany children would play practical jokes by setting candles inside skulls in graveyards to frighten visitors.^[263] Mass transatlantic immigration in the 19th century popularized Halloween in North America, and celebration in the United States and Canada has had a significant impact on how the event is observed in other nations.^[151] This larger North American influence, particularly in iconic and commercial elements, has extended to places such as Ecuador, Chile,^[264] Australia,^[265] New Zealand,^[266] (most) continental Europe, Finland,^[267] Japan, and other parts of East Asia.^[268]
