For some, Halloween can be defined as 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. 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.
But, for the majority, Halloween is a time when we can eat candy and scare each other!
