Trick or Treat Night is typically celebrated on October 31. HOWEVER, if Halloween falls on a Saturday or Sunday, trick or treat will occur on the Friday prior to October 31st.
Trick or Treat October 2021 - will be observed on FRIDAY, October 29, 2021 - 6:00pm to 8:00pm.
In 1992 the Lancaster Inter-Municipal Committee (LIMC) began to encourage municipalities throughout Lancaster County to observe Trick or Treat Night on the same date. The LIMC recommended a policy that trick-or-treating be between 6:00 p.m. and 8:00 p.m. on Halloween (October 31), except when Halloween falls on a Saturday or Sunday, in which case trick-or-treating should be on the prior Friday. The officials of each municipality decide whether to follow that policy, usually by passing a resolution. Twenty-three municipalities notified the LIMC that they would follow that policy and join in the uniform observance that first year. Participation has increased over the years. In several recent years, all sixty municipalities in Lancaster County have had trick-or-treating at the same time.
