What does p.d. mean in biblatex?

Question

I have a biblatex bibliographical reference as follows :

@MISC{Constitutionfr35,
  title = {Constitution du 4 octobre 1958 - Article 15},
  owner = {leo},
  timestamp = {2013.09.20}
}

Which gives in the pdf file : Constitution du 4 octobre 1958 - Article 15 p.d.

What does mean this p.d. ? And how to remove it ?

Yes, in french.lbx one finds nodate = {{pas\space de\space date}{{}p\adddot d\adddot}}, — egreg, Sep 20 '13 at 15:15

As of version 2.6 biblatex implements a "no date" functionality (see Biblatex and entries with no date and § 4.5.8, p. 165 and § 4.9.2.14, p. 204 of the biblatex documentation). If no appropriate field to extract a date from is found (by default these are date, eventdate, origdate and urldate), biblatex falls back to a nodate string. In English nodate is "no date"/"n. d.", in French it happens to be "pas de date"/"p. d.", while in German it is "ohne Datum"/"o. D.".

The easiest way to get rid of the nodate string is to provide a date; preferably by date={2012-08-09} or year={2012}, but really via any of the fields listed above.

If this is not acceptable for you - I appreciate that in your example "constitution du 4 octobre 1958 - Article 15 (1958)" or even "constitution du 4 octobre 1958 - Article 15 (4. 10. 1958)" might feel quite redundant, you can add the following code to your preamble

\DeclareLabeldate{%
  \field{date}
  \field{eventdate}
  \field{origdate}
  \field{urldate}
}

In case no appropriate date label is found, the labeldate field then remains empty and is not printed.

If you care for a finer treatment of nodate, biblatex: getting rid of ›nodate‹ where it's inappropriate might help you.
