The calendar used by the Bajoran people differed from that of Earth. (Bait and Switch: "From Bajor to the Black, Part I", "To Absent Friends", "A Changed World"; The War of the Masters: "Remembrance of the Fallen", "The Only Way to Go")

Bajor canonically has a 26-hour local day. (Star Trek: Deep Space Nine) It is likely the length of its solar year is similar but not identical to Earth's, given that both planets orbit in the habitable zones of a G2V-class star.

Dating structureEdit

Dates under the Bajoran calendar took the form of day and month, followed by an era and a year of that era, and subsequently a descriptive name for the year. An example was Satar 4, Seventh Era 943, Year of the Unseen Harp, which corresponded to 8 June 2397 by Earth's calendar. This could be shortened to Satar 4, 7E943. (Bait and Switch: "From Bajor to the Black, Part I")
