# biblatex uses American date format with british polyglossia [duplicate]

While checking my references I noticed that the urldate is printed in the wrong format. My document is being typeset in British English, where it is common to write the date as Day/Month/Year, compared to the American format Month/Day/Year. The output of my references, however, is in the American format.

\documentclass{article}

\usepackage{parskip}

\usepackage{polyglossia}
\setmainlanguage[variant = british]{english}

\usepackage[backend = biber, citestyle = numeric-comp, language = british]{biblatex}

\begin{filecontents}{references.bib}
@misc{Test,
author = {NanoTemper},
title = {{This is a test title}},
year = {2019},
url = {https://example.com},
urldate = {2019-05-21}
}
\end{filecontents}

\begin{document}
Foo bar\cite{Test}.
\printbibliography
\end{document}


What should I use to get the British date format?

• Is using babel instead of polyglossia an option? tex.stackexchange.com/q/464281/35864, tex.stackexchange.com/q/324849/35864, tex.stackexchange.com/q/432347/35864 (Cf. also tex.stackexchange.com/q/482396/35864) May 22 '19 at 17:00
• Well, I can try if it works, but as I'm using (and also have to) XeLaTeX it could be complicated. Wasn't polyglossia developed as a potential replacement for babelwhen using XeLaTeX?

• BTW: The next version of biblatex will warn about polyglossia to avoid these things slipping past. github.com/plk/biblatex/issues/845 May 22 '19 at 17:03
• Yes, but polyglossia development has effectively stalled in recent years. For languages with Latin script polyglossia offers very little to no advantage at all (it might even be worse for some languages, apparently French would be such a case). If you have non-Latin (especially RTL) scripts, things might be different. May 22 '19 at 17:05
• Okay, thanks! The document looks fine so I guess that babel works fine in my case. And well, the date is in the correct output.
