# Localization for \date command

How can I apply localization for the \date command? For now it seems to just display an arbitrary string.

\documentclass{article}

\author{me}
\date{bla bla bla}

\begin{document}
\maketitle
\end{document}


How can I specify a date in some format? I used datetime2 \date{\DTMdate{2020}{9}{7}} but it gives me compilation error: Paragraph ended before \@dtm@parsedate was complete.

It helps to read the documentation

\date{\DTMdate{2020-9-7}}

You will, of course need to load the datetime2 package with
\usepackage[useregional]{datetime2}

and use the appropriate babel options to select your language.
• It does not seem to reflect my babel/polyglossia configuration. Furthermore, 2020-40-40 also works, which is weird. – Minh Nghĩa Sep 14 '20 at 5:03
• It doesn't seem to really have any validation in it. There is a limited set of languages which are supported by datetime2. You can look at an existing .ldf file for a model of how to add in a missing language. – Don Hosek Sep 14 '20 at 16:10
