  • A note on dates: No specific years are named in Gears of War. All dates are numbered as so many years before or after Emergence Day, B.E. and A.E. respectively. In addition, little is so far known about the Seran Calendar. As a result, the events recorded in the timeline are not given a specific date, only placed within a year. Events that take place in the same year should be listed in chronological order; however this is not always possible because of lack of references, and so the events may not always be in the right sequence.
