Timeline of Xenosaga

==Era of Establishment==
According to Xenosaga Episode III Perfect Guide section 41.1, special-relativistic time dilation means that the following calendar and dates only apply in the reference frame experienced by humanity as they travelled from Lost Jerusalem throughout the cosmos. In particular, they do not apply to Lost Jerusalem itself, in whose reference frame only 1000 to 2000 years passed between when humanity left and the events of Xenosaga Episode III.
Time dilation as it applies in Xenosaga (where the stationary Lost Jerusalem experiences less time passing than the near-lightspeed humanity) is the reverse of how applies in real life (in which high-speed objects experience less time passing than stationary ones). It is unclear whether this is an error or an intentional difference.
