Erros de compilação: (comando \c@days já definido, ambiente{} final ignorado)

$Erros de compilação: (comando \c@days já definido, ambiente{} final ignorado)$

estou tentando criar um calendário usando o pacote calendar.sty (adicionado abaixo). Para isso usei knitr .rnw em R para fazer um loop em uma matriz com os parâmetros do calendário e criei um arquivo .tex. Acredito que o arquivo .tex deve funcionar, mas não compila com os erros abaixo. Tenho certeza de que há alguma colisão nesse pacote, mas não consigo descobrir o que exatamente acontece para poder consertar.

minhas mensagens de erro são essas duas (mas repetidas):

\@calendarwidth=\dimen274
\@currday=\count300
\@numdays=\count301
! LaTeX Error: Command \c@days already defined.
               Or name \end... illegal, see p.192 of the manual.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
...                                              
                                                      
l.148 \end{calendar}
                        
Your command was ignored.
Type  I <command> <return>  to replace it with another command,
or  <return>  to continue without it.

Não tenho ideia de como \c@days funciona ou com o que ele colide, mas por algum motivo ele também ignora o \end{calendar} que deveria encerrar o ambiente, para poder criar um novo ambiente de calendário na próxima página.

meu arquivo .tex (o primeiro erro acontece em \begin{document}, o outro erro em \end{calendar}):

Você tem vários

\newcounter{days}{0}

\newcountersó tem um argumento, então todos devem ser

\setcounter{days}{0}

Então você precisa alocar o contador (apenas uma vez!) no preâmbulo do documento, então adicione

\newcounter{days}
