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.[191][192] In Brittany children would set candles in skulls in graveyards.[193] 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. This larger North American influence, particularly in iconic and commercial elements, has extended to places such as South America, Australia,[194] New Zealand,[195] (most) continental Europe, Japan, and other parts of East Asia.[196] In the Philippines, on the night of Halloween, Filipinos return to their hometowns and purchase candles and flowers,[197] in preparation for the following All Saints Day and All Souls Day (Araw ng mga Patay) on 1 November.
