This page documents events in chronological order that took place in the Ender's Game Universe, or Enderverse.

In Speaker for the Dead and chronologically subsequent novels, the "B.S.C." (before Starways Congress) and "S.C." (Starways Congress) dating system was introduced. It based the calendar around the date of the founding of the Congress.

However, due to the many timeline contradictions of this dating system in the Enderverse, this wiki has decided to use its own dating system for use in articles.

This dating system uses an unofficially recognized, non-canonical calendar in order to provide a relative reference to events in the series. The origin year, or epoch, will be based on the date of the Formic Xenocide, as it is the most prominent event in known Enderverse history and localizes the timeline around the first novel, Ender’s Game. The designations used to label years will be BX (Before the Xenocide) and AX (After the Xenocide). Many events will have approximate dates or will be listed as unknown, as there are many contradictions between canon material that makes it difficult to know for sure when events occurred.

  • In The Swarm, the year was stated to be 2118 AD, equivalent to 97 BX.[5] However, in Shadows in Flight, it was stated that Bean's ship left Earth in 2210 AD.[1] This would put Shadows in Flight at 5 BX, which doesn't line up with the rest of the timeline. Hence, the more recently-published date of 2118 is considered canon on this wiki while the date from Shadows in Flight is not.
