The timeline for these films are very hard to write as there are not many dates given within the films, and most of it is a lot of guess work. So while there are many timeline's out there, no one timeline is correct. I don't believe there can be a correct timeline as the series has many errors.

Here you'll find two timelines I've written. "By Release Date" & "Real Time"

I'm sure there are errors in the timelines, and I'd love to hear everyone's opinion on how the timeline should go, but please read both timelines before writing in your suggestions.

Timeline #1 (By Release Date)
Timeline #2 (By Real Time)
Timeline #3 (By Fangoria)
