Timelines

While the Halloween franchise initially followed one specific timeline and continuity, after the creation of Halloween H20: Twenty Years Later those have multiplied. Halloween III is a standalone film, entirely unrelated to the story of Michael Myers and as such to the rest of the series, so it is not included in the following list.
