This is also a "gimme" -- you've got to account for leap years somehow and
the easiest way to do it is to map them to modulo 4, just as we do in the
Gregorian calendar. (Leap year numbers are divisible by 4, with the
exception of century years, which are leap years only if they are divisible
by 400. UC 0100, UC 0200 and UC 0300 would not be leap years.)

How well you know me! It also fits neatly with your own estimate that it
took about a decade to construct the first permanent colony. It gets
whittled down to 8 years, but the next possible calendar adoption date is
2081 AD, a full 36 years (nearly one and a half generations)
down. Considering how quickly they constructed the subsequent colonies and
evacuated the planet, that's stretching it a bit. It also puts a severe
squeeze on Turn-A's 2345 dateline if that turns out to be AD and not UC.
Of course, if we follow the line of reasoning that says that the first
one's the hardest and things speed up geometrically thereafter, then we
could take the "century" part of UC literally and set UC 0001 at 2149 AD,
over a hundred years after construction began.
But, you know, no matter which of the dates that you present I go with, it
kicks the hell out of my Asian traditional calendar conversion table....

Speaking of calendars and dates they were adopted, the "New Style"
Gregorian calendar was only gradually adopted: Britain and its colonies,
including America, adopted it in 1752, when the error amounted to 11 days,
so that 3 September 3 1752 became 14 September 14 1752, and at the same
time the beginning of the year was put back from 25 March 25 to 1
January. (People rioted in the streets, demanding their 11 days
back....) Russia did not adopt the Gregorian calendar until the October
Revolution of 1917, so that the event (then 25 October 25) is currently
celebrated on 7 November.
BTW, thanks for bringing this up just in time for me to update my Gundam
timeline page over the New Year break! (That conversion table's going to
be a year bear, I just know it!)
