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."

Well, yes, but that is not very important (whether or not the calander
is historical correct).

It's not very important that it is incorrect,
because nobody really  cares for intervals.

 A L L   (!!!) time measures are actually time-intervals.

That doesn't make them important.
Clocks are devices to indicate time.
Time - an entity like UTC, TAI, zone
times. More accurately - to indicate
its less significant part (like "16:41"
of "2024-03-20 16:41" for instance).
Stopwatches - the devices designed to measure
intervals - are different, outnumbered vastly
and lacking serious significance.

Let's simply assume, that the birth of Christ was the event, from
where all calenders today start.

So, there was an event, and that defined the beginning of current time

So we assumed there was. Well, the assumption is
not true, however.

 Possibly you are correct and Christ was not born at that day at all.
 But here this is insignificant, because we're discussing the beginning of our current calender and not the birth of Christ.

I have a different opinion.

For me it is significant that what you're assuming
is false.
