4x02 Unruhe

Book: X-Files #11 ('97): The Howlers

There are three contradictory dates in this episode. Scully's journal dates the epilogue at 10/11.  The original missing persons report (two days prior to the investigation) is dated 9/7.  Finally, the police report of the killer is 4/9 (unlikely).  The above two dates, however, may be both correct as the 10/11 date may be an addendum.

9/9/96 – 9/10/96

4x09 Tunguska (pt. 1)

  The opening date (11/25) of the first Senate Hearing is in error as is the onscreen indication that ten days elapse before then.  Mulder's watch correctly dates 11/25 on the 2nd day of the episode, and the ten days which elapse date from the last Senate Hearing, not the first. 11/23/96 – 11/26/96 X
4x10 Terma (pt. 2)   As above.  While difficult to date, based on a passage of 10 days (erroneously notated after the first Senate Hearing instead of the last), we arrive at the correct period. 11/27/96 – 12/1/96

4x19 Synchrony   Police report indicates date.  (Must be another time anomaly as it occurs after the air date - see here). Blood analysis shows date of 2/25 which contradicts 4x17.
