我教课，在笔记中，秋季学期写着“2015 年秋季”，春季学期写着“2016 年春季”。我可以使用
\the\year
一年。但是有没有类似的东西
\the\season
秋季和春季？如果是，我该如何自定义哪个月份定义学期？
答案1
无需任何额外的包装并提供对半球northern的支持southern：
\documentclass{article}
\newif\ifnorthernhemisphere
\northernhemispheretrue
\newcommand{\season}{%
\ifnorthernhemisphere
\ifcase\month
\or Winter
\or Winter
\or Spring
\or Spring
\or Spring
\or Summer
\or Summer
\or Summer
\or Fall
\or Fall
\or Fall
\or Winter
\fi
\else
\ifcase\month
\or Summer
\or Summer
\or Fall
\or Fall
\or Fall
\or Winter
\or Winter
\or Winter
\or Spring
\or Spring
\or Spring
\or Summer
\fi
\fi
}
\begin{document}
Northern hemisphere
\the\month\ \season
\month=5
\the\month\ \season
\month=9
\the\month\ \season
Southern hemisphere
\month=2
\northernhemispherefalse
\the\month\ \season
\month=5
\the\month\ \season
\month=9
\the\month\ \season
\end{document}
更新这是一个带有可选参数的变体：
\documentclass{article}
\newif\ifnorthernhemisphere
\northernhemispheretrue
\newcommand{\season}[1][\month]{%
\ifnorthernhemisphere
\ifcase#1
\or Winter
\or Winter
\or Spring
\or Spring
\or Spring
\or Summer
\or Summer
\or Summer
\or Fall
\or Fall
\or Fall
\or Winter
\fi
\else
\ifcase#1
\or Summer
\or Summer
\or Fall
\or Fall
\or Fall
\or Winter
\or Winter
\or Winter
\or Spring
\or Spring
\or Spring
\or Summer
\fi
\fi
}
\begin{document}
Northern hemisphere
\season
\season[5]
\season[9]
Southern hemisphere
\northernhemispherefalse
\season
\season[5]
\season[9]
\end{document}

输出：
可以添加一个babel钩子来根据当前语言设置季节名称，甚至使用datetime它来格式化任何日期，例如\season\today。希望有帮助！:)
答案4
biblatex当存在多个或档案项目时的解决方案。
将季节作为出版（元）数据的一部分。
本地化也可以发挥作用。（请注意，并非所有babel/polyglossia语言都定义season相关字符串。）

自动化
更通用的解决方案，使用自定义代码号。
Biberdate当月份设置为某些值时，可以使用字段来表示四季：
my %
seasons = ( 21 => 'spring',
22 => 'summer',
23 => 'autumn',
24 => 'winter' );
...\texlive\2020
\texmf-dist
\source
\bibtex
\biber
\biblatex-biber.tar
\biblatex-biber
\biblatex-biber-2.15
\lib
\Biber
\Date
format.pm
扩展这个想法，但使用通过/级别term的宏处理的自定义字段（），可以完成大学条款和法院条款：BiblatexLatex
xsv说明字段类型和相关命令的使用\forcsvfield，允许根据每个文献条目自定义字段排序（以及 expl3 拆分函数）；以及引用命令中的格式化钩子，允许在文档中间更改引用格式；以及用于本地化的 bibstring。另外还有一个使用字段作为任意代码的输入参数的示例\usefield（此处为图像名称）。
这是关于可以做什么的练习。
用例：集合或概要，或其他批量内容？
如果术语只有少数，则可以始终手动输入，或者可以使用issue字段。@article
