Timeline

The following article is a timeline of the Ace Attorney universe.

Basic reckoning
It is important to note that the years used in this timeline are mostly based on the full date given on a DL-6 Incident case summary file, all other events being portrayed as being relative to other dates as opposed to having a definite point of occurrence. The murder of Gregory Edgeworth is recorded as having occurred on December 28, 2001. By the statute of limitations an unsolved case is closed permanently 15 years after its opening, putting the final resolution of the incident at December 28, 2016. From this, it is possible to construct a timeline of the Ace Attorney universe.

Complications
The developers of the Ace Attorney games, in particular the people in charge of putting down the ages of characters in court records, have not paid much attention to any absolute timeline. This is evident in the fact that characters' ages do not change as the game progresses (except during "flashback" cases), even when a new year passes by. This has led to some inconsistencies in character birthdates. This timeline treats the "present" timeline of an individual game as a "year" (much like school terms that straddle the new year), which resolves some of these issues. More information on this can be found here.

The timeline itself follows. Please note that some of these dates are extrapolations (e.g. "two weeks after Phoenix Wright's disbarment" becomes "May 13") and may not be exactly correct. Nonetheless, it's not likely that the "true" dates will be pinned down.
