By moving Halloween to the last Saturday in October, everyone wins. Kids will be able to trick-or-treat until all hours of the night, parents can enjoy their kids' excitement, and everyone else who is celebrating with other treats can party for as long as they want. No matter how you spin it, getting up to go to work or school with a hangover or sugar crash sounds like hell on earth. Why not avoid such a tragedy?
Halloween falls on Oct. 31 for a reason. According to History.com, the holiday has its origins in the ancient Celtic festival of Samhain—a celebration that was then co-opted by Pope Gregory III:
...people would light bonfires and wear costumes to ward off ghosts. In the eighth century, Pope Gregory III designated November 1 as a time to honor all saints; soon, All Saints Day incorporated some of the traditions of Samhain. The evening before was known as All Hallows Eve, and later Halloween.
To move Halloween would mean disrupting centuries of tradition.
