我正在尝试创建一个简单的议程类，以便为商店设置营业时间和关闭时间。我想根据一天设置不同的时间，所以我使用了 2 个这样的公历：

这是我的议程课程：

private SimpleDateFormat openingFormatter = new SimpleDateFormat("EEEE yyyy.MM.dd ' - Your shop is opening at' HH:mm");
private SimpleDateFormat closingFormatter = new SimpleDateFormat(" 'and closing at' HH:mm'.'");
private GregorianCalendar openingHoursCalendar = new GregorianCalendar();
private GregorianCalendar closingHoursCalendar = new GregorianCalendar();
private int totalDays=365;


Agenda(){
    Calendar c = Calendar.getInstance();

    if (openingHoursCalendar.isLeapYear(c.get(Calendar.YEAR))) {
        totalDays++;
    }

    for(int d=1; d<=totalDays; d++) {

        openingHoursCalendar.set(Calendar.DAY_OF_YEAR,d);
        closingHoursCalendar.set(Calendar.DAY_OF_YEAR,d);

        if(openingHoursCalendar.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY){

            openingHoursCalendar.set(Calendar.HOUR_OF_DAY,8);
            openingHoursCalendar.set(Calendar.MINUTE, 0);

            closingHoursCalendar.set(Calendar.HOUR_OF_DAY,19);
            closingHoursCalendar.set(Calendar.MINUTE, 30);
        }

        else {

            openingHoursCalendar.set(Calendar.HOUR_OF_DAY,1);
            openingHoursCalendar.set(Calendar.MINUTE, 1);

            closingHoursCalendar.set(Calendar.HOUR_OF_DAY,1);
            closingHoursCalendar.set(Calendar.MINUTE, 1);
        }

    }
}

public void printFullAgenda(){

    openingHoursCalendar.add(Calendar.YEAR,-1);
    closingHoursCalendar.add(Calendar.YEAR,-1);

    for(int i=0; i<totalDays; i++){

        openingHoursCalendar.add(Calendar.DAY_OF_YEAR,1);
        closingHoursCalendar.add(Calendar.DAY_OF_YEAR,1);

        System.out.print(openingFormatter.format(openingHoursCalendar.getTime()));
        System.out.println(closingFormatter.format(closingHoursCalendar.getTime()));
    }
}

所以我希望在周日（1:01）和其他日子的 8:00 / 19:30 打印相同的开放和关闭时间，但我得到的却是所有日子的时间完全相同（“你的商店是08:00 开放，19:30 关闭。”）。我真的不明白为什么。有人可以帮我解决这个问题吗？

谢谢
