Common mistakes
- Assuming trick-or-treating always happens on the 31st. Some towns and neighborhoods officially move trick-or-treating to a nearby weekend — check local announcements, or look up other holiday dates with the holiday date finder.
- Ordering costumes too late. Popular costume sizes and styles often sell out in the final two weeks of October.
