We already know that the dates in EU:R are in AUC...
But it seems from the screenshots that Paradox uses standard English month names, which lacks style. Solution: use Roman names for months! (but not the whole calendar system, which would be confusing).
Like:
Martius
Aprilis
Maius
Junius
Quintilis
Sextilis
September
October
November
December
Ianuarius
Februarius
Cool, eh?
