Doug fixed up slash dates in GRAMPS 3.0.1.
In that version, slash dates should be correct.

Doug, could you make a wiki page with how slash date works in GRAMPS. There are conflicting interpretations out there, and obviously, we can only do one thing. As the way GRAMPS works has been done in correspondence with a very knowledgable user, I believe we do it correctly, but it would be interesting to have a wiki page to direct users too who have questions.

Gramps does handle fractional years, but IMO has a bug, which has been
reported.  (Null Edit & save is not an idempotent operator!)

For reference, the Personal Ancestral File software accepts the
fractional form OK.  However, according to their help file, a "/" mark
indicates "uncertainty" in the date.  It can be used in the day number
as well as the year.

That is the wrong way to describe the problem here.  The date
1688/9-01-31 is perfectly unambiguous.  It simply means 1669-01-31
according to Historical calendar (starting Jan 1) or 1668-01-31 (toward
the end of the year 1668 by the Civil calendar).  Although these are
actually Julian dates, the fractional form refers to the convention for
beginning of the year, which is not properly a Julian/Gregorian
question.  Both issues were "taken care of" with the changes of 1752 for
England and friends.

So PAF unwittingly allows us to specify the fractional form the way we
need it.  (But I wouldn't trust any interval calculations it may be giving!)

Cheers,

Martin
