31 Nights of Halloween (formerly 13 Days of Halloween and 13 Nights of Halloween) is an American seasonal programming block on Freeform. It originally began airing in 1998, after the Family Channel became Fox Family, and was continued through the channel's change into ABC Family, and later, Freeform. The 13 Days of Halloween block was created mainly due to the success of the channel's 25 Days of Christmas, which had started two years earlier. The special block lasted from October 19 until Halloween night, covering the thirteen days before the holiday.[1] Starting in 2018, the program aired throughout the whole month of October.[2]
