java陰歷轉陽歷

❶ 陰歷怎麼換算陽歷

沒有固定的轉換法，雖然都是12個月，但是陰歷是5年2閏，陰歷也有大月小月之分，大月是30天小月是29天，陽歷除了4年一次閏年的2月份是29天，平年是28天，象一，.三，五，七，八，十，臘月份，是31天，其餘的月份是30天，是固定的。

❷ 陰歷如何轉換為陽歷

農歷（又稱舊歷、古歷等）與陽歷的轉換，因設計閏月等的處理，很麻煩，還么有找到一個通用的轉換公式，一般人可以通過查表（例如相當多的手機就有此功能）。現在給你以下參考資料：

一，農歷閏月的計算方法
農歷為什麼會有閏月？——農歷置閏月是為了協調回歸年與農歷年的矛盾。
回歸年與農歷年有什麼矛盾呢？先記住：回歸年的總長度為365.2422日，朔望月的長度為29.5306日。
十二個朔望月構成農歷年，長度為29.5306×12=354.3672日，比回歸年少10.88天即將近11天,每個月少0.91天,近1天。
依此，如農歷年某年春節為大雪紛飛的冬天，第二年的春節就會在季節上提前11天，第16個農歷年就會出現在赤日炎炎的夏天。
如按十三個朔望月構成農歷年，長度為29.5306×13=383.8978日，比回歸年又多出18天多。
如果按上述規定製定歷法，就會出現天時與歷法不合、時序錯亂顛倒的怪現象——這就是矛盾。
為了克服這一缺點，我們的祖先在天文觀測的基礎上，找出了「閏月」的辦法，保證農歷年的正月到三月為春季，四月到六月為夏季，七月到九月為秋季，十月到十二月為冬季，也同時保證了農歷歲首在冬末春初。
農歷年中月以朔望月長度29.5306日為基礎，所以大月為30日，小月為29日。為保證每月的頭一天（初一）必須是朔日，就使得大小月的安排不固定，而需要通過嚴格的觀測和計算來確定。因此，農歷中連續兩個月是大月或是小月的事是常有的，甚至還出現過如1990年三、四月是小月、九、十、十一、十二連續四個月是大月的罕見特例。
那麼多長時間加一個閏月呢？最好的辦法就是求出回歸年日數與朔望月的日數的最小公倍數：我們希望m個回歸年的天數與n個朔望月的天數相等，也就是應有等式：
m×365.2422=n×29.5306
在這個等式中我們不能直接求出m和n，但可以求出它們的比例：

這個比例的近似值分別為：

在這些分式中，分子表示回歸年的數目，分母表示朔望月的數目。例如第六個分數式 表示19個回歸年中必須加7個閏月。
19個回歸年中加7個閏月的結果比較：
19個回歸年=19×365.2422=6939.6018(天)
一個朔望月有29.5306天，235個朔望月=235×29.5306=6939.6910(天)
19個回歸年中加7個閏月後，矛盾消除得只差：6939.6910-6939.6018=0.0892（天）——即2小時9分多，這已經是夠精確的了。
所以，農歷就採用了19年加7個閏月的辦法，即「十九年七閏法」，把回歸年與農歷年很好地協調起來，使農歷的元旦（春節）總保持在冬末春初。古人把235個朔望月稱之為「閏周」。
農歷置閏的方法可以使農歷年的平均長度接近回歸年，而農歷中的月又有鮮明的月相特徵，保持了公歷和陰歷兩全其美的特點。
現在置閏的方法是兩個冬至之間，如僅有12個月則不置閏，若有13個月即置閏。置閏的月從「冬至」開始，當出現第一個沒有「中氣」的月份，這個月就是閏月，其名稱是在前個月的前面加一個「閏」字。
農歷閏哪個月？決定於一年中的二十四個節氣。
我國農歷將二十四個節氣分為十二個節氣和十二個中氣。
二十四節氣在農歷中的日期是逐月推遲的，於是有的農歷月份，中氣落在月末，下個月就沒有中氣。
一般每過兩年多就有一個沒有中氣的月，這正好和需要加閏月的年頭相符。所以農歷就規定把沒有中氣的那個月作為閏月。
例如2001年農歷四月二十九日是中氣小滿，再隔一個月的初一才是下一個中氣夏至，當中這一個月沒有中氣，就定為閏月，它跟在四月後面，所以叫閏四月。

❸ 農歷日期和公歷日期怎麼轉換，

網上的萬年歷都是陰歷陽歷自動匹配好的你隨便查找一樣的。

❹ java中怎麼把公歷日期轉成農歷日期

Excel可以實現中陽歷日期轉換成陰歷日期，具體操作如下：

一、使用工具：excel2010

二、操作步驟：

1、假設A1為陽歷日期，B1為轉換後的陰歷日期值，點擊B1單元格輸入以下代碼：

=CHOOSE(MOD(YEAR(LEFT(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),4)&"-"&MID(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),6,2)&"-"&RIGHT(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),2))-1900,10)+1,"庚","辛","壬","癸","甲","乙","丙","丁","戊","己")&CHOOSE(MOD(YEAR(LEFT(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),4)&"-"&MID(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),6,2)&"-"&RIGHT(TEXT(A1,"[$-130000]yyyy年mm月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"dd"),2))-1900,12)+1,"子","丑","寅","卯","辰","巳","午","未","申","酉","戌","亥")&TEXT(A1,"[dbnum1][$-130000]年m月"&IF(--TEXT(A1,"[$-130000]d")<11,"初","")&TEXT(A1,"[dbnum1][$-130000]d日"))

❺ Java怎樣編程實現農歷和陽歷轉換

public class TestNongLi {
public static void main(String[] args) {
// 調用農歷日期轉換陽歷日期方法
System.out.println(ChineseCalendar.sCalendarLundarToSolar(2008, 1, 1));
}
}
// 自定義日歷類
class ChineseCalendar {
// Array lIntLunarDay is stored in the monthly day information in every year from 1901 to 2100 of the lunar calendar,
// The lunar calendar can only be 29 or 30 days every month, express with 12(or 13) pieces of binary bit in one year,
// it is 30 days for 1 form in the corresponding location , otherwise it is 29 days
private static final int[] iLunarmont

❾ java中calendar獲取的時間是陰歷還是陽歷

獲取的是陽歷，補充一點，一般都是用陽歷的
陽歷也叫公歷，來源於西方。比如算星座時、就是按照陽歷（公歷）計算的。
陰歷也叫農歷，來源於我們中國。
比如我們俗稱的八月十五中秋節、清明節、七夕、春節、就是按照農歷來計算的。而元旦、和西方的情人節（2.14）和聖誕節、國慶節、建軍節、黨的生日、都是按照公歷來計算的。

他們的主要區別就在於陽歷是國際通用的，而農歷是我們中國特有的。

編程語言是國外的，怎麼可能用來獲取我們中國特有的時間呢

❿ 可有人知道陰歷和陽歷之間如何轉換，是一個怎樣的演算法！

陽歷日期推算陰歷日期的方法：
陰歷日期是以月亮的圓缺為計月單位，其以逢朔為初一，以月望為十五（大月為十六日），以月晦為二十九日（大月為三十日）。然而目前記時通常用陽歷日期表達，如欲將陽歷日期換算成陰歷日期可以用以下兩種方法：

可以利用公式推算陰歷日期：
設：公元年數－1977（或1901）＝4Q＋R
則：陰歷日期=14Q+10.6(R+1)+年內日期序數-29.5n
（注:式中Q、R、n均為自然數，R<4）
例：1994年5月7日的陰歷日期為：
1994－1977＝17＝4×4＋1
故：Q＝4，R＝1
則：5月7日的陰歷日期為：
14×4+10.6(1+1)+(31+28+31+31+7)-29.5n
=204.2- 29.5n
然後用29.5去除204.2得商數6......27.2，6即是n值，余數27即是陰歷二十七日。
