Unknown Century

While the era goes by the Common Era calendar in terms of numbering, those who live on the abundant colony clusters far from Earth refer to the age as the Unknown Century ((未知) (の) (世紀)). This is the timeline where Mobile Giant Gundam 87 takes place.

For the colonies, the periods of time across the seventy year span of Gundam 87 are divided into three; the Bubble Era, the Warring Era, and the Recovery Era.
