I am trying to display the year and also the parentheses in bold
Author (year):
Here is a MWE
\documentclass[12pt, bibliography=totocnumbered, listof=totoc]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage{filecontents}
%Bibliotheken
\usepackage
[style=ext-authoryear,labelnumber, useprefix=true,

doi=false,isbn=false,url=false,
uniquename=false,bibencoding=utf8, date=year, giveninits=true, terseinits=false, dashed=false]
{biblatex}
%Colon after year
\renewcommand{\labelnamepunct}{\mkbibbold{\addcolon}\space}
%Year and parantheses in bold
\DeclareFieldFormat{date}{\mkbibbold{#1}}
\DeclareFieldFormat{parens}{\mkbibbold{\mkbibparens{#1}}}
\begin{filecontents}{\jobname2.bib}
@Article{Hansen2011,
author = {Hansen, Peter R. and Lunde, Asger and Nason, James M.},
title = {The Model Confidence Set},
journal = {Econometrica},
year = {2011},
volume = {79},
number = {2},
pages = {453-497},
url = {https://EconPapers.repec.org/RePEc:ecm:emetrp:v:79:y:2011:i:2:p:453-497},
}
\end{filecontents}
\addbibresource{\jobname2.bib}
\begin{document}
\textcite{Hansen2011}
\printbibliography
\end{document}
I tried using \mkbibbold in some way, but it didnt work well. A short explanation would be great.
