biblatex-chicago 在参考书目中显示两次日期

我已经使用 biblatex 多年了，但最近开始在我的 bib 文件中使用日期字段而不是年份。我现在用 biblatex-chicago 创建了一个参考书目，其序言如下。

看起来一切良好，但我得到了两次日期：

Name, Firstname. YEAR. "Title." *Journal* Vol, no, (Month-Day-Year): page-page.

我查阅了文档，但找不到如何摆脱第二个日期字段的方法，因为根据芝加哥风格指南，该字段不仅无用，而且甚至不是必需的或必要的。

\documentclass[paper=a4,draft=on,fontsize=12pt,headings=small]{scrartcl}
\usepackage[utf8]{inputenc}     
\usepackage[british]{babel}
\usepackage[authordate,backend=biber]{biblatex-chicago}

\bibliography{publications.bib}
\begin{document}

\nocite{Author:year}

\printbibliography

\end{document}

如果您尝试使用该date字段，您会发现，如果完整日期比年份更具体，样式只会显示两次日期。我不知道 CMS 的具体细节，但我认为这种行为是有道理的，但如果它确实违反了样式要求，请联系作者biblatex-chicago并将其报告为错误（我上次给他发电子邮件时，他很快就得到了回复）。

的日期处理非常复杂，因此当您弄乱它时，请再三检查其他一切是否正确。对于报纸（带有）和许多其他条目类型biblatex-chicago的引用，最好不要隐藏第二个更精确的日期。@articleentrysubtype = {magazine},

一个简单且没有副作用的解决方案是，.bib如果不需要（或不需要）文件中的月份和日期信息，则删除这些信息。

自动删除重复日期的一种方法是在内部宏中更积极地删除字段clear+datefield。该宏在第一次打印日期后执行。如果我们告诉它删除日期字段，我们就不会第二次打印它们。

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[authordate, backend=biber]{biblatex-chicago}

\renewbibmacro*{clear+datefield}[1]{%
  \clearfield{#1year}%
  \clearfield{#1month}%
  \clearfield{#1season}%
  \clearfield{#1endyear}%
  \clearfield{#1endmonth}%
  \clearfield{#1endseason}%
}
