1712 for Sweden we know for sure. 708 AUC / 46BC we know less well.
There's several commentaries on the web for this that lay out the
conflicting evidence for the number of days (422, 444 or 445), so it's
hard to declare that the winner if we don't know what the actual total
is :)

There's also other year reckonings for other cultures that produce
very long results depending on what you tag as "a year"
