The year 4000 is a leap year in the Gregorian calendar, and that has
been true since the calendar's inception. There have been proposals
to add a rule that would make the year 4000 common, but such proposals
have never been widely adopted. Of course, calendars including such a
rule are perforce no longer the Gregorian calendar, just as the
Gregorian calendar is not the same as the Julian.
However, I do believe some Eastern European countries officially
adopted such a derivative calendar rather than the Gregorian... So as
it stands now, whether or not 4000 is a leap year may depend on your
location.
