Introduction
This DC Animated Universe timeline that I devised consists of the series Batman: The Brave and The Bold.
However, please note that this timeline is unofficial. That is, this timeline is created from my own personal observations and research. In order to make sure that this timeline maintains it consistency and validity, I had to incorporate many assumptions and constraints.
An assumption is easy enough to understand. I take a vague statement and add my own thoughts on what that means. For example, in "The Power of Shazam!", Black Adam states he was languishing for 5000 years. I take how the series' present is the 21st century so I simply subtract 5000 years from 2000 to get a date of 3000.
A constraint is something, in this case fact, that is binding and can not be modified. For example, in several episodes over the years, Batman is explicitly stated to be eight years old when his parents are murdered. This fact is a constraint, and is used to calculate years other events relative to it.
With that said, here is the The Brave and The Bold Timeline.
