In 1992 the Lancaster Inter-Municipal Committee began to encourage municipalities throughout Lancaster County to observe “Trick of 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.
