[Tex/LaTex] Disable month in biblatex bibliography

Question

Currently my bibliography items are printed like this:

R. B. Griffiths, Nonanalytic Behavior Above the Critical Point in a Random Ising
Ferromagnet, Physical Review Letters 23 (July 1969), pp. 17–19 (cit. on p. 10).

which took quite some time to fiddle with a custom bibliography style in biblatex. The remaining issue is the month field. Instead of (July 1969) it should just print (1969). I have read every bit of the biblatex documentation concerning dates and there are hundreds of options but not once is there a possibility mentioned how to completely disable the month.

Do I have to dig down even further into biblatex or is there an easy or documented way to change the default behaviour?

Answer 1

You could add one or both of the following commands to your preamble:

\AtEveryBibitem{\clearfield{month}}
\AtEveryCitekey{\clearfield{month}}
