termcal我怎样才能标记跨度超过一天的事件？
例如，当我有为期三天的期末考试时，整个考试必须标记为期末考试；当我有期中休息时，整个考试必须标记为期末考试。
我当前的代码：
\documentclass[12pt]{article}
\usepackage[margin=0.5in, paperheight=8.5in, paperwidth=13in]{geometry}
\usepackage{termcal}
\pagenumbering{gobble}
\newcommand{\Class}{
\calday[Monday]{\classday}
\calday[Tuesday]{\classday}
\calday[Wednesday]{\classday}
\calday[Thursday]{\classday}
\calday[Friday]{\classday}
\calday[Saturday]{\noclassday}
\calday[Sunday] {\noclassday}
}
\newcommand{\Holiday}[2]{
\options{#1}{\noclassday}
\caltext{#1}{#2}
}
\begin{document}
\paragraph*{Tedu's Schedule:}
\begin{center}
\begin{calendar}{5/1/2017}{53}
\setlength{\calboxdepth}{.3in}

\Holiday{1/1/2018}{New Year's Day}
\Holiday{2/25/2018}{EDSA Revolution Anniversary}
\caltext{5/31/2017}{End of Classes}
% By the way, how can I reset the number of days counter in here?
\caltext{8/1/2017}{Start of Classes}
