what year something happened is a statement that requires a lot of interpretation and presuppositions
like, what is an event in the context? what calendar is used? what are the commonly agreed upon limits of the type of event?
just because interpretation seems easy to you and you don't recognise that it happens, doesn't mean it isn't necessary
there are no simple facts, because human language is quite complicated
@troglodyt @LotusHopper Sorry Troglodyt but that's a whole pile of pseudo-intellectual horseshit. There is zero... ZERO... ambiguity to asking what Miley Cyrus' birthday is or what year man landed on the moon. Come back to earth space man.
