If it only was that easy :-)

During the years, sometimes a couple of days have gone "missing".

And depending on where you live, this could have happened sooner
or later. eg, the Russian October Revolution is celebrated in November,
I believe, because 2 weeks are gone :-) ... Or the other way around,
for that matter.

And the Russians were years later with adjusting their calendar compared
to others... So this all makes "date" a rather strange thingy :-)
