晚上好，我不知道如何在第一页上获取正确的日期，\maketitle过去我已经这样做过，没有任何问题。大文档，因此嵌套：
root: -> title
-> any other file needed
-> the one forgotten file
我得到以下文档
主要的：

Title.tex，应该显示\today：
\begin{titlepage}
\pagestyle{empty}
\begin{tikzpicture}[remember picture, overlay]
\draw[fill=black] (current page.north west) rectangle (current page.south east);
%Striscia verticale Green4!25

最后是简化版本，其中包含 5 个不同的文件，如下所示，它们也将合并到主文件或根文件中：
\section*{1st day}
\blindtext
\section*{2nd day}
\begin{wrapfigure}[22]{l}{0.63\textwidth}
\centering
\includegraphics[\width=0.6\textwidth]{example-image-a}
\end{wrapfigure}
\blindtext
\blindtext
\subsection*{3rd day}
\begin{wrapfigure}[22]{l}{0.63\textwidth}
\centering
\includegraphics[\width=0.6\textwidth]{example-image-a}
\end{wrapfigure}
\blindtext
\blindtext
\section*{4th day}
\begin{wrapfigure}[22]{l}{0.63\textwidth}
\centering
\includegraphics[\width=0.6\textwidth]{example-image-a}
\end{wrapfigure}
\blindtext
\blindtext
\subsection*{6th day}
\begin{wrapfigure}[22]{l}{0.63\textwidth}
\centering
\includegraphics[\width=0.6\textwidth]{example-image-a}
\end{wrapfigure}
\blindtext
\blindtext
and so on for the other important days
是的，wrapfig 与 PS 技巧一起使用来突出显示重要内容，并且许多包用于进一步绘制一些 pgf 图，而且我还在进行一场战争以让siunitx命令\qty{}{}使用文本字体相应地显示数字，但这不是他的帖子的目的。
我已经尝试创建一个虚假的\maketitle，我打算把它放在哪里，但什么也没有，也\date{\today}没有用，所以我尝试在titlepage env包含的文件内部和外部进行操作（看看所有那些注释行）。
如果有必要的话，2周前我将 TeXstudio 从 4.6.3 升级到了 4.7.0 版本。
谢谢大家的帮助。
我根据在 overleaf 中找到的个人日记模板进行了一些工作（https://www.overleaf.com/latex/templates/personal-journal-template/cnhkpjpfkrdn), 阅读 @campa 的评论时，我怀疑日志中对 \day 的递归重新定义可能会影响 \today 的行为。我说得对吗？
如果是这样的话，我应该失去 100 分声誉，因为我没有注意到如此明显的事情......我很抱歉让你浪费时间在我这个愚蠢的问题上。
答案1
看看@campa 的评论，我盲目地遵循了 overleaf 模板…… https://www.overleaf.com/latex/templates/personal-journal-template/cnhkpjpfkrdn
第 11 条戒律，永远不要相信互联网上的任何东西。很抱歉你们浪费了一个小时来帮助我，非常感谢大家
因此，使用大写字母的新定义解决了问题，直到它没有解决问题……但最终罪魁祸首是\def\day{}在fancyhf序言部分。现在它按预期工作了！
