Hello everyone (and especially ryan123450),
Since it’s something that I’d have done first anyway, here’s my look at how the new Star Trek Encyclopedia revises and extends the last version of the Star Trek Chronology. This isn’t intended as a nit-pick or criticism of the new book, and it’s not a detailed transcript of all the available information. I’ve only had time for a brief look, but here goes:
The new timeline is very brief, running to three pages. Most major events are dated. Star Trek: Insurrection is in 2375, and Star Trek: Nemesis is in 2379. The last date is 2387, for the Hobus supernova. Whether this means that the “Prime” timeline is subsequently “overwritten” by the new course of events isn’t stated, but the first date is 1957, so I doubt that’s the intention.
The really major innovation is that each season of Star Trek: The Next Generation, Star Trek: Deep Space 9 and Star Trek: Voyager are listed as extending into the following year. For example, the first season of TNG is assigned to 2364, but a note in brackets says that it continues into 2375. Obviously, the seventh season of VOY starts in 2377, but continues into 2378. How that applies in practice isn’t clear. In general, the entries in the main body of the text seem to support the old exact correlation between each season and a calendar year. As far as I could see, the only changes seem to be ones where it don’t involve too much editing (although that’s only a guess on my part). “Shades of Gray” now falls in 2366, although “Peak Performance” is still dated to 2365. “In Theory” is dated to late 2367, and the whole of “Redemption” Parts 1 & 2 are in 2368.
