Smalyshev added a comment. Herald added a project: Discovery. So I took a look at this one, and we have a weird situation here - probably since https://phabricator.wikimedia.org/T99674 is undecided, but it's more about external representation than internal one. In Wikidata/Wikibase, 1 BCE is stored as -0001. In XSD 1.1 it should be 0000. OK, so should we just add 1 to all negative years? Well, but what about Q1 with "13798 million years BCE" - it shouldn't be suddenly -13797999999, right? That would be weird. Maybe just add 1 to dates that have precision of "years" and below? But that may lead to some weird things too.
Now, we also have possible year "0". Which is not the same as 1BCE and stored as 0000. Should we ignore such year or make it 1BCE too? Also, when we translate Julian to Gregorian, should "1 BCE (Julian)" - with no days - become "-0001-12-30" ISO Gregorian or "0000-01-01" ISO Gregorian? Should we do Gregorian->Julian conversion for dates without days at all or should we keep the year and just put 01-01 on it? Note that since Gregorian and Julian years are not in perfect sync, we can't really know in which Gregorian year the event with non-dated Julian year is.
