I have no opinion about what the different calendar applications should do. But this discussion went beyond that narrow issue. And I just wanted to point out that assertions like "Almost nobody who writes about ancient history specifies dates in the calendars that were used at the time" and "using the Julian calendar when talking about events that occurred before 1752 ... is a special case that doesn't generalize" don't seem to be supported by facts.
