I think a year or year+month is probably granular enough. I can see
accidental re-assignment of URNs in the course of a decade, but already
find it harder to see that happening in the course of a year. If a URN
is re-assigned within a year, I can only conclude that the assigning
organisation has no proper internal bookkeeping for URNs. Adding a more
specific date probably won't improve their bookkeeping. I can still
imagine two employees assigning the same URN on the same day to two
different resources.

On the other hand, I have no objections against adding a month + day.
The only drawback is that it adds 6 spurious characters to each URN --
not something I worry about.
