有大佬可以分享一下javaGUI界面的万年历源码（带农历，节气节日之类的）嘛。非常感谢！
java编写日历
我给你贴上我在java核心技术中看到的代码吧,当然没有输入年份和月份,是按照当前时间创建的,写有我写的注释,应该能看的懂
/*
* 2012年5月13日10:37:58
* 日历程序
* Function:
* 显示当前月份的日历
* 总结
* 1. 0-11分别代表1-12月
* 1-7分别代表周日-周六
* 2. 使用GregorianCalendar对象的get方法（参数）获取月，日，年等信息
* 3.

public class CalendarTest {
public static void main(String[] args) {
//construct d as current date构造一个日期
GregorianCalendar d = new GregorianCalendar();
//获取今天是这个月的第几天
int today = d.get(Calendar.DAY_OF_MONTH); //Calendar.DAY_OF_MONTH作为参数调用，得到今天是这个月的第几天
int month = d.get(Calendar.MONTH); //月份
d.set(Calendar.DAY_OF_MONTH, 1); //设置d的日期是本月的1号
int weekDay = d.get(Calendar.DAY_OF_WEEK); //获取当天位于本星期的第几天，也就确定了星期几，值的范围是1-7
int firstDayOfWeek = d.getFirstDayOfWeek(); //获取一星期的第一天,我们得到的是Calendar.SUNDAY,因为我们一星期的第一天是周日
int indent = 0; //为了定位本月第一天，定义索引
while (weekDay != firstDayOfWeek) {
//注意，月份用0-11代表1-12月，为了清晰起见，使用常量代替，下面获取月份得到的实际是当前月-1的值，所以我们要加1
//System.out.printf("当前星期的第%d天,位于当月的第%d天, 现在是%d月\n",
// weekDay, d.get(Calendar.DAY_OF_MONTH), d.get(Calendar.MONTH)+1); //Test Code
indent++;//缩进个数+1
d.add(Calendar.DAY_OF_MONTH, -1);//当前天数-1，如果现在是1号，则执行本条代码后，时间变为上一个月最后一天
weekDay = d.get(Calendar.DAY_OF_WEEK); //重新获取当天位于本星期的第几天
}
String[] weekDayNames = new DateFormatSymbols().getShortWeekdays();//获取简短形式的星期字符串数组
//System.out.println(weekDayNames.length);getShortWeekdays()得到的数组的长度是8，下标为0的是没有值1为星期日...7为星期六
//注释代码1
//Java核心技术的代码
/*

System.out.println();//换行
for (int i=1; i<=indent; i++)//确定一星期的一天位置，利用上面indent
System.out.printf("\t");//如用方式2，则这里内容是四个全角空格
//实现输出日期

用JAVA帮忙编写一个日历查询系统，非常感谢~！

C语言编程 关于万年历程序的问题
int number=(year-1)+(year-1)/4-(year-1)/100+(year-1)/400+yearDay(year,month,day);
//计算的是这一天是这一年的第几天
number=number%7;
//一个星期有七天，
return number;
//返回为0代表星期天，1代表星期一,.........
