使用自由欄位，將下面的程式放進去，並修改 schedule, members 就可以了
-------------------------------------------------------------------
<script type="text/javascript">
var schedule = {year:2010, month:6, day:12, duration:7, number:2};
var members = ["Rick", "Nash", "yvonne", "tcsu","irenetsung","lao1206","linchuhs"];
var schedule = {year:2010, month:6, day:12, duration:7, number:2};
var members = ["Rick", "Nash", "yvonne", "tcsu","irenetsung","lao1206","linchuhs"];
var info = getInfo();
// document.write("<div style='border:1px solid red; padding:2px'>");
// document.write("值日生: ");
document.write("<span style='color:red'>" + info.members + "</span>");
document.write(" <span style='font-size:11px; color:#aaa'>(" + info.duration + ", 下次: " + info.next + ")</span> <p>");
document.write("麻吉值日生公約→ 我最棒： <br>");
document.write("肩負起Po文、回討論、關心新麻吉的責任喲 ... 就是幫助大家都能互相學習交流~");
// document.write("</div>");
// 以下是程式碼，請不要理我 ....
function getInfo()
{
var baseDay = new Date(schedule.year, schedule.month - 1, schedule.day);

var dStart = Math.floor(NumOfDays(baseDay, today) / schedule.duration) * schedule.duration;

var nextStr = "";
