I think what would be most useful to users is for a message to to appear in the echo area informing the user that the result is given in the Gregorian calendar and other calendars may apply whenever the result is a historical date (before 1900 if we use the Russian case as the cutoff). The message could also inform about Emacs functions to convert between calendar systems, or even offer keyboard shortcuts to do the conversion immediately (in the case of calendar). Although there are calendars other than Gregorian still in use today, the message might be seen as noise if it appears for every calendar calculation, and people wanting those calendars probably don't need reminding that the date may differ between calendars.
