I also do not claim that this is in any way an OFFICIAL timeline of the Avatar series. It is merely a piece of fanwork, nothing more. I'm sharing it so other fans can use and enjoy it. If you do use it, credit would be greatly appreciated.
Speaking of appreciation, I'd like to give an inordinate amount of thanks to my friend and beta, Stingrae, for her support, suggestions, editing skills, and being the levelheaded one when I was sleep-deprived and going insane over details. I owe her cookies. Lots and lots of cookies.
Notes and references are at the bottom if you're curious as to how I arrived at this jumble of conclusions. I reserve the right to make changes to this calendar as the need arises. (And it probably will arise at some point...)( Calendar under the cut! )
