How this list works
Halloween beyond your own block. This page collects every event and program in our San Jose listings whose title names Halloween, trick-or-treating, pumpkins, costumes, ghosts or the like, dated between October 1 and November 1. 14 are still ahead. Each one opens its listing page, which links to the organizer’s own page and shows the date we last checked it. Dates are in Pacific Time.
