The frontend formatter used to add a hint about the calendar model in specific cases: year > 1581 && year < 1930 || year <= 1581 && calendar === 'Gregorian' || year >= 1930 && calendar === 'Julian' <sup>Gregorian</sup> There is also special CSS applied to that element in https://github.com/wmde/ValueView/blob/6dcc56edcffc97da131d5f4ac6ebd12eacd7aadd/src/experts/TimeValue.css, so the sup would need a class since the wrapper class does not exist anymore.
