You guys have missed a gregorian calendar reference:
From Star Trek II: The Wrath of Kahn
McCOY: 'Beware Romulans bearing gifts.' Happy Birthday, Jim.
KIRK: Romulan Ale! Why, Bones, you know this is illegal.
McCOY: I only use it for medicinal purposes. I got a boarder ship that brings me in a case every now and then across the Neutral Zone. Now don't be a prig.
KIRK: 2283.
McCOY: Yeah, well it takes this stuff a while to ferment.
Sure seems to me like Kirk is reading a vintage date from the bottle. So we can say that the movie takes place at least by 2283, or possibly even later than that given McCoy's line about it taking a while to ferment.
This wouldn't quite work if "Space Seed" took place in 2266 and TWOK is 15 years later, which would be 2281.
Alternately we could assume 2283 is a stardate meaning the ale was bottled sometime after "The Squire of Gothos" which would make it about 15 years old, and McCoy's line works. Though it seems weird to me to express a vintage to a specific date rather than a year. But, who's to say, I guess? Maybe that's just how Romulan Ale rolls.

That is Wrath of Khan. Khan not Kahn. Kahn is a surname, used by many people. And some of those people might possibly share my disgust at all the terrible massacres committed by various Turkic and Mongol khans over the centuries and be angry that you confused their surname with the most sinister and evil sounding title in all of Human history. It is quite possible that more people have been murdered by Khans than by Nazis and Commies combined.
There is a difference between a calendar and the year count that it uses.
A calendar involves the order and names of months, the number of days in each month, how the calendar compensates for the fact that there is a fractional and not a whole number of days in a year, etc., etc.
A year count is counting the years from a specific year or whole date that is the era or epoch of the calendar.
The Julian calendar was used by the Christian states in Europe during the middle ages. But the Christian states in the Iberian Peninsula used the year count called the Spanish era or the era of Caesar, counting the years from what we call 38 BC. In Spanish era 1387 the Kingdom of Aragon adopted the
Anno Domini year count, making the year now AD 1348. The Kingdom of Valencia switched to
Anno Domini in 1396/1358, the Kingdom of Castile in 1421/1383, and the Kingdom of Portugal in 1460/1422. And everyone over 38 could joke they were now 38 years younger, and I don't know what jokes the people under 38 made.

During the middle ages different places started the year on different dates. So if one traveled between different places that both used the
Anno Domini year count one might still travel between different years in the calendars of different places.
So you have made several assumptions.
1) You have assumed that the 2283 is a year and not some stardate or other dating system.
2) You have assumed that if 2283 is a year it must be an Earth year and not a year in another planet's calendar.
3) You have assumed that all future Earth year counts will be
Anno Domini year counts, and not use many other eras which have been used in Earth calendars in the past and present, despite the fact that there is strong evidence for the use of different year counts in different episodes
4) You have assumed that the only calendar used in Earth's future will be the Gregorian calendar, despite the fact that many different calendars are used on Earth at the present.
5) You have assumed that use of the Gregorian calendar implies use of the
Anno Domini year count, and that use of the
Anno Domini year count implies use of the Gregorian calendar, even though the
Anno Domini year count was started a thousand years before the Gregorian calendar.
