And the answer will be, most likely,  wrong. Just checked
with postgres database. It doesn't know that the first date
is gregorian and the other is julian - and it doesn't know
the difference. I bet you don't know the difference too.
Welcome to the real world?

Just read the link you provided, poor stinker.
"But, of course, this calendar is only valid for Great Britain and dominions, not other places. Since it would be difficult and confusing to try to track the actual calendars that were in use in various places at various times, PostgreSQL does not try, but rather follows the Gregorian calendar rules for all dates, even though this method is not historically accurate."
BTW, have you already learnt what a function is?
Is "for any element of the domain" clause still
confusing you, poor stinker?
