# Month/Year Format in Latex

This should be a easy question, but I didn't find answer from googling. The date format I wan is: Month(letter), Year(numerical). For example, I want: November, 2014. Of course, I can manually achieve this requirement. But I think LaTeX can do better. Any ideas will be greatly appreciated. Thanks!

• How do you want to use it? Do you want to specify it using a regular date-like format, yet LaTeX should output it using (only) "Month, Year"? As in, \mydate{2014/11/14} should output November, 2014? – Werner Nov 14 '14 at 18:37
• Thanks Werner for the swift reply! I am not sure how to specify it, but the ultimate output I want is: month, year. For example: November, 2014. If I put \date{\today}, it will contain date which I do not want. – Daryl Nov 14 '14 at 18:43

You can use the datetime package to customize the formatting; a little complete example:

\documentclass{book}
\usepackage{datetime}

\newdateformat{monthyeardate}{%
\monthname[\THEMONTH], \THEYEAR}

\begin{document}

\monthyeardate\today

\end{document}


produces

With datetime2 package, there is at least two ways to achieve this. The first is a bit similar to the answer by Gonzalo:

\documentclass[english]{book}
\usepackage{datetime2}

\makeatletter
\newcommand{\monthyeardate}{%
\DTMenglishmonthname{\@dtm@month}, \@dtm@year
}
\makeatother

\begin{document}

\monthyeardate

\end{document}


The other way, I think, is more LaTeXian:

\documentclass{book}
\usepackage[en-US]{datetime2}

\begin{document}

\today

\DTMlangsetup{showdayofmonth=false}
\today
\DTMlangsetup{showdayofmonth=true}

\today

\end{document}


Some notes:

• For the first way to work, english parameter for \documentclass seems to be required. Alternatively, english can be omitted and en-US or en-GB given for datetime2 as \usepackage[en-US]{datetime2}
• The second way requires en-US or en-GB even when english has been given for \documentclass.
• The ways were tested with pdflatex, version pdfTeX 3.14159265-2.6-1.40.16 (TeX Live 2015).

More details are provided in:

A simple solution that requires no extra packages is the following:

\documentclass{article}

\renewcommand{\today}{\ifcase \month \or January\or February\or March\or %
April\or May \or June\or July\or August\or September\or October\or November\or %
December\fi, \number \year}

\begin{document}
\today
\end{document}


The result:
