$Errores de compilación: (el comando \c@days ya está definido, el entorno end{} se ignora)$

Estoy intentando crear un calendario usando el paquete calendar.sty (agregado a continuación). Para eso utilicé knitr .rnw en R para recorrer una matriz con los parámetros del calendario y creé un archivo .tex. En mi opinión, el archivo .tex debería funcionar, pero no se compila con los siguientes errores. Estoy bastante seguro de que hay alguna colisión con ese paquete, pero parece que no puedo descubrir qué sucede exactamente para poder solucionarlo.

mis mensajes de error son esos dos (pero repetidos):

\@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.

No tengo idea de cómo funciona \c@days o con qué colisiona, pero por alguna razón también ignora el \end{calendar} que debería finalizar el entorno, por lo que puede crear un nuevo entorno de calendario en la página siguiente.

mi archivo .tex (el primer error ocurre en \begin{document}, el otro error en \end{calendar}):

\newcounter{days}{0}

\newcountersolo tiene un argumento por lo que todos deberían ser

Luego debe asignar el contador (¡sólo una vez!) en el preámbulo del documento, así que agregue

\newcounter{days}
