文章提供计算农历天干地支及当年属相的算法源程序，使用的语言为Javascript、VBScript、C#等。
一、C# 代码（1）：
原来还准备自己写算法，并研究农历规则。发现那太难和麻烦了，光是农历的推算那就我等专门研究历法的人一下搞懂的。后来发现。NET类库也提供一些基础的农历类System.Globalization.ChineseLunisolarCalendar。我改装了一下如DateTime时间形式。代码如下。实现了 公历农历转换的功能。但是只能算到1900~2100年之间的。基本够日常使用了。源代码如下：

if (isLeap) month -= 1;
this.time = time;

throw new Exception("参数年份时间不在支持的范围内,支持范围：" + cc.MinSupportedDateTime.ToShortDateString() + "到" + cc.MaxSupportedDateTime.ToShortDateString());
if (Month < 1 || Month > 12)
throw new Exception("月份必须在1~12范围");
cc = new System.Globalization.ChineseLunisolarCalendar();
if(cc.GetLeapMonth(Year)!=Month&&IsLeap)
throw new Exception("指定的月份不是当年的闰月");
if (cc.GetDaysInMonth(Year, IsLeap Month + 1 : Month) < DayOfMonth || DayOfMonth < 1)
throw new Exception("指定的月中的天数不在当前月天数有效范围");
year = Year;

isLeap = IsLeap;
time = DateTime.Now;
}
//// <summary>

public static ChinaDateTime ToChinaDateTime(DateTime Time)

}
}
}
二、C#代码（2）：
1、农历类的使用
.net框架不支持直接将日期转换成农历格式的字符串，那么要将显示农历格式的日期，就只要自已写代码了。不过由于已经有了ChineseLunisolarCalendar类实现了公历转换为农历日期的功能，所以要写这样的代码也比较简单。需要用到ChineseLunisolarCalendar以下几个主要方法：
int GetYear (DateTime time) 获取指定公历日期的农历年份，使用的还是公历纪元。在每年的元旦之后春节之前农历的纪年会比公历小1,其它时候等于公历纪年。虽然农历使用传说中的耶稣生日纪元似乎不太妥当，不过我们确实已经几十年没有实行一个更好的纪年办法，也只有将就了。
int GetMonth (DateTime time) 获取指定公历日期的农历月份。这里要注意了，由于农历有接近三分之一的年份存在闰月，则在这些年份里会有十三个，而具体哪一个月是闰月也说不准，这里不同于希伯来历。以今年为例，今年闰七月，则此方法在参数为闰七月的日期是返回值为 8，参数为农历十二月的日期时返回值为13
bool IsLeapMonth ( int year, int month) 获取指定农历年份和月份是否为闰月，这个函数和上个函数配合使用就可以算出农历的月份了。
int GetDayOfMonth (DateTime time) 获取指定公历日期的农历天数，这个值根据大月或者小月取值是1到30或者1到29, MSDN上说的1到31显然是错的, 没有哪个农历月份会有31天。
int GetSexagenaryYear (DateTime time) 获取指定公历日期的农历年份的干支纪年，从1到60，分别是甲子、乙丑、丙寅、….癸亥, 比如戊戌变法、辛亥革命就是按这个来命名的。当然算八字也少不了这个。
int GetCelestialStem (int sexagenaryYear) 获取一个天支的天干, 从1到10, 表示甲、乙、丙….，说白了就是对10取模。
int GetTerrestrialBranch (int sexagenaryYear) ) 获取一个干支的地支，, 从1到12, 表示子、丑、寅、…今年是狗年，那么今年年份的地支就是“戌”。
有了这几个方法，显示某天的农历月份日期、农历节日等都是小菜一碟，算命先生排八字用这几个方法，又快又准确，写出的代码也很短。
2、几种东亚农历类的区别
经过我的测试，ChineseLunisolarCalendar, JapaneseLunisolarCalendar, KoreanLunisolaCalendarr, TaiwanLunisolarCalendar这四种日历，无论哪一种，以2006年2月6日为参数，调用它们的GetMonth方法得到的结果都是1，GetDayOfMonth得到的结果都是8。想想也是，我们过的端午节和韩国的不太可能不是一天。
但是调用GetYear方法得到结果就有区别了ChineseLunisolarCalendar和KoreanLunisolarCalendar都返回2006，也就是公历纪年，TaiwanLunisolarCalendar的返回值是95，依然是民国纪年，JapaneseLunisolarCalendar的返回值是18, 平成纪年。
另外的一个区别是这四种日历的MinSupportedDateTime和MaxSupportedDateTime各不一样，以下是对照表：
日历类 MinSupportedDateTime MaxSupportedDateTime
ChineseLunisolarCalendar 公元1901年1月初1 公元2100年12月29
TaiwanLunisolarCalendar 民国1年1月初1 民国139年12月29
JapaneseLunisolarCalendar 昭和35年1月初1 平成61年12月29
KoreanLunisolarCalendar 公元918年1月初1 公元2050年12月29
韩国农历类支持的最小日期为918年(也即高丽王朝建立的年份)，以此而论，中国农历类支持的最小日期不说从商周算起，从汉唐算总该没问题吧？微软公司啊，又在“厚彼薄此”，唉。
其次，日本还以天皇纪年，如果哪天xxxx, 岂不是使用JapaneseLunisolarCalendar写出的程序都有问题啦？
3、写自已的日期格式化器
昨天看了一篇文章，说目前大家用的“农历”这个术语是文革时期才有的，目的是反封建。这里为了省事，还是继续使用这个术语。而英文名称ChineseLunisolarCalendar太长，我自己的代码中就用ChineseCalendar为相关功能命名，这个名字也还过得去吧。
我原先设想自定义一个类，使得能写出这样的代码：
string s= DateTime.Now.ToString(new MyFormatProvider());
就能得出我想要的农历日期字符串，经过测试却失败了，依据我的分析，微软公司在.net框架中把日期时间型的格式写死了，只能依据相关的地区采用固定的几种显示格式，没法再自行定义。而前文已经说过，而所有的相关格式微软公司都放到一个名为culture.nlp的文件中(这个文件在以前的.net框架是一个独立的文件，在.net 2.0被作为一个资源编译到mscorlib.dll中。) (我的这个不能为DateTime写自已的格式化器的观点没有资料佐证，如有不当之处，请大家指正)
虽然不能为DataTime写自定义的格式器，但还有另外一个途径，就是为String类的Format方法写自定义格式化器，我测试了一下，效果还不错，调用方式如下：
string s= String.Format(new ChineseCalendarFormatter(), "{0:D}",DateTime.Now);
可以得到“二〇〇六年正月初九”
string s= String.Format(new ChineseCalendarFormatter(), "{0:d}",DateTime.Now);
可以得到“丙戌年正月初九”
虽然没有前面所设想的方便，但也还能接受，全部代码帖出如下：
第一个类，主要是封装了农历的一些常用字符和对日历处理的最基本功能
using System;
using System.Collections.Generic;
using System.Text;
using System.Globalization;
public static class ChineseCalendarHelper
{
public static string GetYear(DateTime time)
{
StringBuilder sb = new StringBuilder();
int year = calendar.GetYear(time);
int d;
do
{
d = year % 10;
sb.Insert(0, ChineseNumber[d]);
year = year / 10;
} while (year > 0);
return sb.ToString();
}
public static string GetMonth(DateTime time)
{
int month = calendar.GetMonth(time);
int year = calendar.GetYear(time);
int leap = 0;
//正月不可能闰月
for (int i = 3; i <= month; i++)
{
if (calendar.IsLeapMonth(year, i))
{
leap = i;
break; //一年中最多有一个闰月
}
}
if (leap > 0) month--;
return (leap == month + 1 "闰" : "") + ChineseMonthName[month - 1];
}
public static string GetDay(DateTime time)
{
return ChineseDayName[calendar.GetDayOfMonth(time) - 1];
}
public static string GetStemBranch(DateTime time)
{
int sexagenaryYear = calendar.GetSexagenaryYear(time);
string stemBranch = CelestialStem.Substring(sexagenaryYear % 10 - 1, 1) +
TerrestrialBranch.Substring(sexagenaryYear % 12 - 1, 1);
return stemBranch;
}
private static ChineseLunisolarCalendar calendar = new ChineseLunisolarCalendar();
private static string ChineseNumber = "〇一二三四五六七八九";
public const string CelestialStem = "甲乙丙丁戊己庚辛壬癸";
public const string TerrestrialBranch = "子丑寅卯辰巳午未申酉戌亥";
public static readonly string[] ChineseDayName = new string[] {
"初一","初二","初三","初四","初五","初六","初七","初八","初九","初十",
"十一","十二","十三","十四","十五","十六","十七","十八","十九","二十",
"廿一","廿二","廿三","廿四","廿五","廿六","廿七","廿八","廿九","三十"};
public static readonly string[] ChineseMonthName = new string[]
{ "正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二" };
}
第二个类为自定义格式化器：
using System;
using System.Collections.Generic;
using System.Text;
using System.Globalization;
using System.Threading;
public class ChineseCalendarFormatter : IFormatProvider, ICustomFormatter
{
//实现IFormatProvider
public object GetFormat(Type formatType)
{
if (formatType == typeof(ICustomFormatter))
return this;
else
return Thread.CurrentThread.CurrentCulture.GetFormat(formatType);
}
//实现ICustomFormatter
public string Format(string format, object arg, IFormatProvider formatProvider)
{
string s;
IFormattable formattable = arg as IFormattable;
if (formattable == null)
s = arg.ToString();
else
s = formattable.ToString(format, formatProvider);
if (arg.GetType() == typeof(DateTime))
{
DateTime time = (DateTime)arg;
switch (format)
{
case "D": //长日期格式
s = String.Format("{0}年{1}月{2}",
ChineseCalendarHelper.GetYear(time),
ChineseCalendarHelper.GetMonth(time),
ChineseCalendarHelper.GetDay(time));
break;
case "d": //短日期格式
s = String.Format("{0}年{1}月{2}", ChineseCalendarHelper.GetStemBranch(time),
ChineseCalendarHelper.GetMonth(time),
ChineseCalendarHelper.GetDay(time));
break;
case "M": //月日格式
s = String.Format("{0}月{1}", ChineseCalendarHelper.GetMonth(time),
ChineseCalendarHelper.GetDay(time));
break;
case "Y": //年月格式
s = String.Format("{0}年{1}月", ChineseCalendarHelper.GetYear(time),
ChineseCalendarHelper.GetMonth(time));
break;
default:
s = String.Format("{0}年{1}月{2}", ChineseCalendarHelper.GetYear(time),
ChineseCalendarHelper.GetMonth(time),
ChineseCalendarHelper.GetDay(time));
break;
}
}
return s;
}
}
这段代码中间处理格式那部份稍做改进，就可以支持更多的日期格式。
有了这两段代码为原型，要实现计算和显示一个日期的农历日期及其它功能，基本上就很容易了。

农历FLASH源码、旧历FLASH日历、旧历FLASH时钟
在FLASH中，制作时钟、日历都不难。在网上搜索一下，也会有一大遍源码等着你去下载。但不知是我孤陋寡闻，还是咋地。在网上还没见过农历的代码，在民族文化如此繁荣的中国。竟然没有人来研究这个。实在是有点遗憾。花点时间，研究了一下。随后把源码附上。希望大家共同讨论。其中难的就是闰月部分。
制作过程，前面的就不说了。直接发代码吧。
新建一倒计时类"Taoshaw_data.as"。
然后输入如下代码：
class Taoshaw_data extends Date {

2、用法上面也写得有。在FLASH中调用的时候。请参考如下代码：
/*
getFullYear();获取新历年份
getnewMonth();获取月份,如果像本例这样，独立用数组表示，就直接用getMonth()获取，因为数组会少一个值.是从0开始的.
getDate()获取多少号.
getSeconds();获取秒值
getDay();获取星期几
getHours();获取小时（整点）
getMinutes();获取分数
getTaosJYear();获取中国农历年.
getTaoJMonth(); 获取中国农历月.
getTaoJDay();获取中国农历日.
getTaoJNianZhu();获取年柱
getYueZhu();获取月柱
getRiZhu();获取日柱
getShiceng();获取时辰
getJieQi();获取二十四节气
*/
//定义新Taoshaw_data类，因为Taoshaw_data类继承于data类，所以在此直接使用此类即可.
