Individual episodes & movies arranged by air date.
This list consists of all live action Star Trek series (except Enterprise) and movies in stardate order. It includes JJ Abrams' first Star Trek movie, as it's beginning shows repercussions from events seen in the last TNG movie.
TNG Season 1 Episodes are not listed in stardate order, as it would create continuity issues regarding Wesley Crusher's status.
Minor Star Trek II spoiler:
If TOS is viewed in stardate order, it explains why Khan recognized Chekov, as some episodes with him have stardates before Khan's first encounter with the crew of the Enterprise.
This list shows the order of which Stargate TV shows can be watched. The list also includes the chronological order of Kino webisodes of SGU and is slightly more detailed than existing lists.
