In working on a totally unrelated TMP era project, part of my research involves nailing down a few dates – based on when the events of Star Trek: The Motion Picture took place. Now Memory Alpha, a commonly accepted reference for canon Trek, lists those events as occurring in 2273. However, in their entry for the movie itself, they list those events as taking place starting on stardate 7410.2. Entering that date into the stardate calculator I use would give us a date of Monday, November 27, 2271.
Just thought I’d shoot that out there.
