# Moving the date in amsart

I am using the amsart documentclass. I use \maketitle at the beginning of my file:

\date{\today}
\maketitle


The problem is that amsart places the date in a footnote at the bottom of the first page, and I want the date to appear at the top of the page, under the author (where the date would appear using the article documentclass). Is there a way to change this behavior?

You may use the standard class article with additional packages amsthm, mathtools, and maybe amsrefs to have a standard class with most features of the AMS classes but standard class lookalike.

Alternative you may use amsart and combine it with the title definition of article:

\documentclass{amsart}

\makeatletter
\renewcommand\maketitle{\par
\begingroup
\renewcommand\thefootnote{\@fnsymbol\c@footnote}%
\def\@makefnmark{\rlap{\@textsuperscript{\normalfont\@thefnmark}}}%
\long\def\@makefntext##1{\parindent 1em\noindent
\hb@xt@1.8em{%
\hss\@textsuperscript{\normalfont\@thefnmark}}##1}%
\if@twocolumn
\ifnum \col@number=\@ne
\@maketitle
\else
\twocolumn[\@maketitle]%
\fi
\else
\newpage
\global\@topnum\z@   % Prevents figures from going at top of page.
\@maketitle
\fi
\thispagestyle{plain}\@thanks
\endgroup
\setcounter{footnote}{0}%
\global\let\thanks\relax
\global\let\maketitle\relax
\global\let\@maketitle\relax
\global\let\@thanks\@empty
\global\let\@author\@empty
\global\let\@date\@empty
\global\let\@title\@empty
\global\let\title\relax
\global\let\author\relax
\global\let\date\relax
\global\let\and\relax
}
\renewcommand*\@maketitle{%
\newpage
\null
\vskip 2em%
\begin{center}%
\let \footnote \thanks
{\LARGE \@title \par}%
\vskip 1.5em%
{\large
\lineskip .5em%
\begin{tabular}[t]{c}%
\@author
\end{tabular}\par}%
\vskip 1em%
{\large \@date}%
\end{center}%
\par
\vskip 1.5em}
\renewcommand{\author}[1]{\gdef\@author{#1}}
\makeatother

\begin{document}
\title{title}
\author{me}
\date{\today}
\maketitle
\end{document}


Or you may redefine only \@maketitle of amsart:

\documentclass{amsart}

\makeatletter
\renewcommand*\@maketitle{%
\normalfont\normalsize
\@mkboth{\@nx\shortauthors}{\@nx\shorttitle}%
\global\topskip42\p@\relax % 5.5pc   "   "   "     "     "
\@settitle
\ifx\@empty\authors \else \@setauthors \fi
\ifx\@empty\@date \else {\vskip 1em \vtop{\centering\large\@date\@@par}}\fi% MY CHANGE
\ifx\@empty\@dedicatory
\else
\baselineskip18\p@
\vtop{\centering{\footnotesize\itshape\@dedicatory\@@par}%
\global\dimen@i\prevdepth}\prevdepth\dimen@i
\fi
\@setabstract
\normalsize
\if@titlepage
\newpage
\else
\vskip\dimen@\relax
\fi
} % end \@maketitle
\let\@makefnmark\relax  \let\@thefnmark\relax
%  \ifx\@empty\@date\else \@footnotetext{\@setdate}\fi% MY CHANGE
\ifx\@empty\@subjclass\else \@footnotetext{\@setsubjclass}\fi
\ifx\@empty\@keywords\else \@footnotetext{\@setkeywords}\fi
\ifx\@empty\thankses\else \@footnotetext{%
\def\par{\let\par\@par}\@setthanks}%
\fi
}
\makeatother

\begin{document}
\title{title}
\author{me}
\date{\today}
\maketitle
\end{document}


I've marked my changes of the original definitions of amsart at this alternative with comments % MY CHANGE.

But if you want a title page instead of a in page title head, have also a look at Resources for title page and front matter design.

A simpler way to patch the \maketitle command in amsart is

\usepackage{etoolbox}
\makeatletter
\patchcmd{\@maketitle}
{\ifx\@empty\@dedicatory}
{\ifx\@empty\@date \else {\vskip3ex \centering\footnotesize\@date\par\vskip1ex}\fi
\ifx\@empty\@dedicatory}
{}{}

The spirit is just the same as Schweinebacke's answer, but this code doesn't require to copy the entire definition of \@maketitle and \@adminfootnotes.
Wouldn't it be a good idea to use at least \undefined at the last argument of \patchcmd to get an error, if the patch fails, e.g., because of a typo mistake or change at amsart? –  Schweinebacke Nov 29 '11 at 14:32
