when is stranger things day

Stranger Things Day is observed on November 6 each year. It originated from the within-show timeline—the day Will Byers disappeared in Hawkins in season 1—and has since become a global fan celebration with premieres, events, and new merchandise tied to the franchise, particularly around the release or premiere of new Stranger Things content. The most recent notable observance linked to the date is the world premiere and related festivities for Stranger Things 5, which were planned for November 6, 2025, in Los Angeles, with fan events and streaming plans surrounding that date.
