Quick question: I'm confident that 3333 is going by the Yokudan calendar rather than the Tamrielic. And seeing as I just now started reading up on the way the Yokudans did their years, I don't really know what year this correlates to yet.
The Yokudan years are basically just Tamrielic years plus 1636; however, since we only know of Yokudan dates from 'our' First Era, we don't know if they employ an era system or not... regardless 3333 would be #E 4969 (of whatever era you happen to be in); if they don't use eras, it would be 2E 413 to us...
