kalendarium package

[Jens-Olaf Lindermann]

Seems that kalendarium is abandoned. I want to use it but get an error
message 'undefined control sequence'. Any ideas to use the package anyway?

Here is my mwe (or M-n-WE)

\documentclass{scrbook}
\usepackage{fontspec}
\usepackage[abbreviate=false,dayfmt=latin,era=auc]{kalendarium}
\begin{document}

\KalDate{2022}{2}{2}

\end{document}

you can try

\ExplSyntaxOn
\cs_set_eq:NN \str_case_x:nn \str_case_e:nn
\prg_new_eq_conditional:NNn \str_case_x:nn \str_case_e:nn {T,F,TF}
\ExplSyntaxOff
