comment Did Antarctica remain entirely unvisited by humans until the early 19th century?
Of course, there is the claim that the Chinese went there in the 15th century (by Gavin Menzies). But his works are deemed of non-historical studies quality (which is certainly true). en.wikipedia.org/wiki/Gavin_Menzies. As said elsewhere, it is doubtful that a journey (coming back) reached such a place before the 18th century (the KonTiki experiment showed long journeys were possible with primitive maritime technology, but not in such dire conditions). Accidental landings in the 18th century by lost boats might have existed, but they left no written traces.

comment How accurately could ancient astronomers find latitude and longitude?
Some information about ancient latitude/longitude navigation system is in the 1421 book by Gavin Menzies. However, information in this book is certainly to be taken with caution, and I do not have my copy offhand.

comment In the French Republican calendar: were Quintidis holidays?
Being French native speaker I can propose a translation: The excess work imposed by the ten-day rhythm could also be a reason for the rejection the new time was the victim of. [...] The creators of the laws on decadi observance of year VI also accounted for this dimension of the issue by allowing for additional rest on the afternoon of quintidi This matches what I was told in history lessons (which I recall only partially). This makes 1.5 days of rest every 10 days, matching approximatively the 1 every day (in fact, a bit better).

comment When did the British monarch become an emperor?
So, if I understand correctly, there is a British Empire, but no British Emperor (just a British King/Queen that happens to be Emperor elsewhere)?
