VB 農歷的計算方法

'下面是一個關于VB的農歷算法

'提供基本計算方法，具體應用自己補充

'日期數據定義方法如下

'前12個字節代表1-12月為大月或是小月，1為大月30天，0為小月29天，

'第13位為閏月的情況，1為大月30天，0為小月29天，第14位為閏月的月

'份，如果不是閏月為0，否則給出月份，10、11、12分別用A、B、C來表

'示，即使用16進制。最后4位為當年家農歷新年-即農歷1月1日所在公歷

'的日期，如0131代表1月31日。

'GetYLDate函數使用方式如下tYear為要輸入的年，tMonth為月，tDay為

'日期，YLyear是返回值，返加農歷的年份，如甲子年，YLShuXing返回

'的是屬象，如鼠。IsGetGl是設置是不是通過農歷取公歷值，如果是，

'前三個返回相應的公歷日期，而且返回值是一個公歷日期。

VB.NET的陽歷與農歷轉換的算法

根據經驗, 這個算法非常復雜. 經過查找，終于得到一些資料, 在此愿與大家分享。首先陰歷以月為基本單位，一個月以新月出現的那一天為始直至下一個新月出現的前一天。由于月亮公轉的周期介于29到30天之間，陰歷的一個月也就由新月出現時刻的早晚或是29天或是30天。大月為30天，小月為29天。與陽歷不同的是，大小月在不同的年中不固定。如春節的前一天常稱為大年三十，但有不少年如2000年的陰歷十二月只有29天。由于十二個月的時間較陽歷年即地球繞太陽公轉一周的時間短11天左右. 為了使陰歷年與陽歷年保持相對穩定，每隔兩三年就需要加入一個閏月。大約每十九年要加入七個閏月。而二十四節氣則是由地球在繞太陽公轉的軌道上的位置確定的。以每年的冬至為始，每15度為一個節氣。是故二十四節氣在陽歷的每月中有大概固定的日期。古時以二十四節氣指導農耕，這就是陰歷又稱農歷的原因。其中陽歷下半月的十二個節氣又稱為中氣。中氣出現的時刻和閏月的確定有直接的關系。陰歷的計算有下列四條規則： 1．所有新月和節氣出現的時刻的計算以東經120度即東八區標準時為準。但計算1929年以前的陰歷時應以北京即東經116度25分的當地時為準。 2．新月出現的一天為一個月的第一天。如某個節氣的出現時刻也在這一天，則不論該節氣的出現時刻是否比新月晚，一律算落入新的一個月中。 3．每年的冬至總是落在這年的十一月中。從一年的冬至的第二天起到下一年冬至這一天止的這段時間稱為一歲。如一歲中有十三個新月出現，則這一歲為閏歲，要加入一個閏月。 4．閏歲中第一個沒有中氣的月為閏月。因為一歲中只有十二個中氣，所以閏歲中至少有一個月沒有中氣，也存在有兩個月沒有中氣的可能性。但這種情況下只有第一個沒有中氣的月為閏月。閏月的前一個月為幾月則該閏月稱為閏幾月。根據以上信息, 我們知道農歷是根據天文觀測進行指定的（也許可以在天文學的書上找到說明）。為了簡化轉換計算, 很多程序人員設計了基于"時間段內查表"方法的例程. 更具體的說明和源碼請參考下面這些資料：

下面是一個關于VB的農歷算法

'日期數據定義方法如下

'前12個字節代表1-12月為大月或是小月，1為大月30天，0為小月29天；

'第13位為閏月的情況，1為大月30天，0為小月29天；

'第14位為閏月的月份，如果不是閏月為0，否則給出月份，10、11、12分別用A、B、C來表示，即使用16進制；

'最后4位為當年家農歷新年-即農歷1月1日所在公歷的日期，如0131代表1月31日。
