When Does the Original “Star Trek” Series Season Three (1968) Take Place?

"Star Trek" (sometimes released as "Star Trek: The Original Series") season three is a science fiction television show showran by Fred Freiberger and released September 20th, 1968. So when is "Star Trek" season three set? 

It takes place on the fictional Star Trek timeline in the year: 

2269? AD 

We know this because . 

Although the famous "stardate XXXX.X" captain's records that open most episodes and some films were mistaken for years on the Gregorian calendar, there is no one-to-one relationship between them. As identified in the biography "Gene Roddenberry: The Myth and the Man Behind Star Trek": "They marked off sections on a pictorial depiction of the known universe and extrapolated how much earth time would elapse when traveling between given points, taking into account that the Enterprise's warp engines would be violating Einstein's theory that nothing could exceed the speed of light. They concluded that the 'time continuum' would therefore vary from place to place, and that earth time may actually be lost in travel. 'So the stardate on Earth would be one thing, but the stardate on Alpha Centauri would be different,' Peeples says." so they are relative to long distance travel and not an absolute calendar. HOWEVER, actual years on the Gregorian calendar began to be used later. 

It is the fourth chronological TV show in the Star Trek universe and can be watched at its timeline point.
