51	ENT	1	The Andorian Incident	Said to have happened 3,000 years before the episode
52	ENT	1	The Andorian Incident	Said to have happened 3,000 years before the episode. This would seem to contradict Soval's claim that Vulcans did not achieve star flight until 1,500 years after the Great Awakening
53	TOS	3	That Which Survives	The planet was described as being thousands of years old. This is about three thousand years ago
54	DS9	3	Destiny	The prophecies where said to have been made 3,000 years ago

63	DS9	7	What You Leave Behind, Part 1	Said to have happened 2,000 years before the episode
64	TNG	6	Rightful Heir	Said to have happened 1,500 years before the episode. This date chosen to fit in with the non canonical but more specific date Data gives for the death of Kahless, and with the subsequent construction of the Boreth monastery
65	TNG	6	Rightful Heir
66			From the episode script	Data states that Kahless has been dead for 1,547 years. This is that long prior to the episode date of 2367
67	TNG	6	Rightful Heir	Koroth states that the Klingons have been waiting for the return of Kahless for over fifteen centuries. This is 1501 years prior to the episode date of 2367.

93	ENT	4	The Forge	Soval said it took the Vulcans nearly 1,500 years after the great Awakening to travel to the stars. This is 1,499 years after. Note that since the Romulan splinter group left at the time of the Awakening, Vulcans must have already had interstellar flight then. Most likely the Romulan exodus was aboard a slower than light sleeper ship or generational vessel, and this date refers to the Vulcan invention of warp drive.
94	DS9	3	Defiant	Dukat said the founding had been 500 years ago
95	TNG	5	Time's Arrow, Part 1
96	TNG	6	Time's Arrow, Part 2
