If civilization continues to the year 9999, is the idea to go to year 10.000, or...?
It seems like it'd get increasingly impractical as the years go on to hundreds of thousands and millions of years to write them out that way, but then...I guess technically one may already do this with the preceding years, so future's fair game for it?
we should really update this to "After when some people thought Jesus was born but they fucked up by 4-6 years. Also why is there no year zero?"
AWSPTJWBBTFUB4YAWITNYZ doesn't really roll off the tongue, though. Maybe it's better if someone can translate that into Latin.
Edit:
Google Translate says "Post cum quidam putant natus est Jesus, sed eruditionis 4-6 annis. Cur etiam annus nullus est nullus?" so I propose "Post cum"
