RE: year

When dating historical events, the Gregorian calendar is of limited use 
unless it was the contemporary calendar at the time.

Notice that this applies even in the twentieth century, with 'old-style' vs 
'new-style' dates for events in pre-bolshevik Russia.

I wonder if anyone knows of a good, serious methodology for representing 
antiquarian dates?
