I'm seeing a little bug in the weekly timetable template. The bottom line of the calendar is not always drawn. For example, this works as expected:
\begin{calendar}{\hsize} \day{}{} \day{}{hello, world} \day{}{} \day{}{} \day{}{} \finishCalendar \end{calendar}
But this omits the bottom line:
\begin{calendar}{\hsize} \day{}{} \day{}{hello, world} \day{}{} \day{}{} \day{}{} \day{}{} \finishCalendar
\end{calendar}
