I want to use the datetime
package to get the name of the months, but the package does not support one of the languages I am using. I am writing a template (with a .sty
file), so I want to be able to use different languages. My question is: How can I define the name of the months for this language that is not supported?
Here is the code:
\documentclass[5p,a4paper]{elsarticle}
\usepackage[utf8]{inputenc}
\usepackage[english,nynorsk]{babel}
\usepackage{appendix}
\RequirePackage{datetime}
\RequirePackage{etoolbox}
% Commands for how a date is displayed:
\newdateformat{MonthYearDateFormat}{%
\monthname[\THEMONTH], \THEYEAR
}
\newdateformat{DayMonthYearDateFormat}{%
\THEDAY \ \monthname[\THEMONTH], \THEYEAR
}
\newdateformat{YearDateFormat}{%
\THEYEAR
}
\patchcmd{\MaketitleBox}{\footnotesize\itshape\elsaddress\par\vskip36pt}{\footnotesize\itshape\elsaddress\par\parbox[b][36pt]{\linewidth}{\vfill\hfill\textnormal{\today}\hfill\null\vfill}}{}{}%
\patchcmd{\pprintMaketitle}{\footnotesize\itshape\elsaddress\par\vskip36pt}{\footnotesize\itshape\elsaddress\par\parbox[b][36pt]{\linewidth}{\vfill\hfill\textnormal{\today}\hfill\null\vfill}}{}{}%
\begin{document}
\selectlanguage{nynorsk}
\begin{frontmatter}
\title{title}
\author[University]{O. Nordmann}
\address[University]{University}
% Date:
%------------------------------------
\newdate{dateName}{19}{04}{2022}
\renewcommand*{\today}{\MonthYearDateFormat\displaydate{dateName}}
% Options for displaying date: \MonthYearDateFormat, \DayMonthYearDateFormat or \YearDateFormat
%
\begin{abstract}
abs
\end{abstract}
\end{frontmatter}
\appendix
\section{A}
\end{document}
This produces the error:
Package datetime Warning: No month names provided for language 'nynorsk' on input line 45.
I would prefer a solution using datetime over some other solution. I tried using datetime2
, but I found it simpler to use datetime
. Is there a way to define the monthnames for the language nynorsk?
Edit: The reason I used datetime
and not datetime2
is because datetime2
has no command that displays the monthname of the currently selected language. As I want my template to be able to handle multiple languages, I can not define a dateformat using names specific for a language.
Also, the names are basicually the same as for those in the language option norsk
(which works fine in datetime
). However, I want the rest of the document to be typset in nynorsk
. As such I would welcome a solution that uses the names from norsk
but typsets the rest of the document in nynorsk
.

You can add Nynorsk support yourself by patching the relevant commands in the
datetime
configuration file for (Bokmål) Norsk. I checked on ScriptSource and it seems that only the weekday names need changes.(I changed from April to May to better show the difference).
