When Does the Animated Film "Batman: Mystery of the Batwoman" (2003) Take Place?
"Batman: Mystery of the Batwoman" is a superhero animated film written by Alan Burnett with Michael Reaves [loosely adapting the Batman story in "Detective Comics" #233 (1956) by Edmond Hamilton as well as the second Batman story in "Batman" #116 v1 (1958) by anonymous] that released October 21st, 2003. So when is "Mystery of the Batwoman" set?
It takes place on an alternate timeline of the fictional DC Films Universe in the year:
We know this because, when pulled up on the Batcomputer, Kathleen "Kathy" Duquesne's file clearly reads, "BIRTH DATE: 04-23-81" and "AGE: 22" while Roxanne "Rocky" Ballantine's file says, "BIRTH DATE: 09-11-82" and "AGE: 20".

2003 AD
We know this because, when pulled up on the Batcomputer, Kathleen "Kathy" Duquesne's file clearly reads, "BIRTH DATE: 04-23-81" and "AGE: 22" while Roxanne "Rocky" Ballantine's file says, "BIRTH DATE: 09-11-82" and "AGE: 20".
1981 + 22 = 2003
and
1982 + 20 = 2002.
This seems contradictory until one considers the precise month and day dates: Rocky’s birthday being in September means she is currently 20 and will turn 21 at that point in 2003 AD and Kathy’s birthday being in April means she turned 22 at that point in 2003 AD and is currently 22. Therefore it must be between April and September of 2003 AD.
This Watchtower Database video examines its exact setting.
It is a third chronological animated film to feature Bruce Wayne/Batman and can be watched in between "Justice League Unlimited" season 2 episode 3 "The Doomsday Sanction" (2005) and season 2 episode 4 "Task Force X" (2005).
