The dating of the final season of "" has presented controversy. The standard assumption about stardates, as well as the regular correspondence between seasons and in-universe years, would place the entire season in the year 2377—the season begins with stardate 54014.4 and ends with 54973.4. However, the episode "" features a celebration of the 315th anniversary of Zefram Cochrane's first contact with the Vulcans, which would set the episode on April 5, 2378. The fansite Memory Alpha thus places the final eight episodes of the season ("" through "") in 2378, with other sources following suit.
