How to print only year (no day/month) with Biblatex

In analogy to Disable month in biblatex bibliography? you can just disable the month and day fields with the commands

\AtEveryBibitem{\clearfield{month}}
\AtEveryBibitem{\clearfield{day}}

For a short moment there came to my mind that there could be a caveat with the urldate field that declares when a URL has been checked, but biblatex even takes care of this. The urldate is still printed as full date. Compare the MWE and its output below:

\begin{filecontents}{test.bib}
@BOOK{test,
author= {A. Author},
title = {A Title for a Book},
date = {2012-10-08}
},
@ONLINE{test2,
author = {A. Author},
title = {Some title},
url = {http://example.com},
urldate = {2013-01-08}
}
\end{filecontents}

\documentclass{article}
\usepackage{biblatex}
\addbibresource{test.bib}

\AtEveryBibitem{\clearfield{month}}
\AtEveryBibitem{\clearfield{day}}

\begin{document}
\nocite{*}

\printbibliography
\end{document}

Is this what you intend to do? If not, please provide a MWE to work with.


The question and answer @benedikt-bauer linked to has since been updated with a new answer which contains a nicer solution:

The biblatex package option date=year should also work.

One may also need labeldate=year as well; or alldates=year and then something like urldate=short

Which should be valid for biblatex version 2.8 (2013) and higher.


Updates: For clarity, here are the relevant (shortened) parts of the manual:

date=year,short,long,terse,comp,ymd,iso default:comp
This option controls the basic format of printed date specifications.

<datetype>date=year,short,long,terse,comp,ymd,iso default:comp
Similar to thedateoption but controls the format of the <datetype>date field in the datamodel.

alldates=year,short,long,terse,comp,iso
Sets the option for all dates in the datamodel to the same value. The date fields in the default data model are date, origdate, eventdate and urldate.
