This doesn't really work yet in the UI. Basically,
you could only enter
sth like 6th c. BC which in this case would not be correct.
6. century BC for birth date and 5. century BC for death date is both
correct and possible.
1st Millenium BC would be possible and correct, but it
is a bit too
wide. That's the only thing supported right now.
We will be working on improving this situation.

Hello,
I'm beginning with wikidata and didn't find how to add a date which
is not exact. In fact I found [1], which would gain clarity with an
example, but the given format is refused when I try to use it. For
example, I want to add birth and death date for Pittacus of
Mytilene[2], for which I know no accurate value, but it something
like -650 to -570, with something like a quarter century accuracy.
Actually, looking at the English Wikipedia, -640 to -568 is given,
but without sources unfortunatly. Well, for the sake of the example
lets ignore that, what input should I provide to the birth day
property to match my previous description?
