More detail
This is a bug in our implementation:(in function QQuickCalendarModelPrivate::getCount, qquickcalendarmodel.cpp line 107)
QDate r = QDate(1, 1, 1).addDays(days);
int years = r.year() - 1;
int months = r.month() - 1;
return 12 * years + months + (r.day() / t.day());
it uses days to calculation number of months, and when the date stops in February, there will only be 28 days and failed to add extra 1 to return value. Please also see attached test project's output.
