請問知道陽曆怎麼計算陰曆
陰曆就是農曆,是中國傳統的 陽曆就是公曆,是國際通用的 一般不用算的，你去日曆或手機上能查到的，陽曆旁邊就會標出陰曆的!
1、陽曆日期推算陰曆日期的方法：
前已述及陰曆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）。
如要知道1984年6月8日是陰曆幾日？可以利用公式推算陰曆日期： 設：公元年數－1977（或1901）＝4Q＋R, 則：陰曆日期=14Q+10.6(R+1)+年內日期序數-29.5n （注:式中Q、R、n均為自然數，R4） 例：1994年5月7日的陰曆日期為： 1994－1977＝17＝4×4＋1 故：Q＝4，R＝1 則：5月7日的陰曆日期為： 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，餘數27即是陰曆二十七日
2．公曆換算為農曆
二十四節氣在黃道上的位置是固定的，但各年有平年和閏年之分，就使得回歸年天數與實際天數不等，每年在日曆上可差一天。這樣可以將陰曆經過任意整回歸年在現在的日曆上查到陽曆（陽曆一年相當陰曆的月數為 365．2422/29．530588＝12．36827個月）。例如，可先在1995年的日曆上查得與（該年）陰曆對應的陽曆日期，這樣就找到了臨時落腳點，也就是找到了陰陽互換的關鍵。例如，可先以陰曆四月初一（日）為引數，在1995年日曆上查到對應的陽曆為4月30日。由於已經計算出經過的月數，將經過的月數的尾數（小數）化為日，加在4月30日上，就得到經過（1995－1070）整年數的陽曆日期，也就是起始陰曆日期對應的陽曆日期，即得到了待查的日期為4月30日加上0．64957×29．530588得到（1070年）5月19．1821840日。這樣就得到了所給例子的陰陽曆日期換算結果……」。 0．64957月的由來，
（1995－1070）×12．36827＝11440．64957月
已知依澤公生於梁龍德二年（922）六月二十一日，依下表提供的2099年各月初一日的公曆月日數，可以算出龍德二年六月二十一日的公曆月日數 公元2099年農曆各月初一日的公曆月日
（2099－922）× 12．36827＝1455．45379月
餘數為 0．45379月 × 29．530588日＝13．4O日
因2099年五月初一日（包括該年闖二月）在公曆6月19日，加上計算所得的13日為龍德二年六月初一日的公曆月日，即該年7月2日，則該年農曆六月二十一日為該年7月22日。
3．計算結果的訂正
實際上上列公曆換算為農曆時常有較大的誤差，如熙寧三年四月初一日為公曆1070年5月13日，而不是5月19日。通過中國曆法所用的於支記日法求算所用兩歷的干支，對所求結果加以訂正。
如，馬依澤公生於回曆310年3月20日，自回曆曆元起算共曆日數為： 自回曆元旦至其3月20日，共歷79日。
自回曆元年元旦至309年元旦，共歷113個閏年196個平年。又回曆曆元在公曆622年7月16日，已知該日的干支序數為50，癸丑日，減1（因自甲子起算），餘49應加入下列算式中，
（309 × 354＋113＋79＋49）÷60＝1827．116667 0．116667 ×60＝7

java中怎麼把公曆日期轉成農曆日期
Excel可以實現中陽曆日期轉換成陰曆日期，具體操作如下：
一、使用工具：excel2010
二、操作步驟：
1、假設A1為陽曆日期，B1為轉換後的陰曆日期值，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”))
如圖：
2、輸入代碼後按回車鍵，這時B1返回A1對應的陰曆日期，如圖：
如何根據陽曆日期推算出對應的陰曆日期
陽曆日期推算陰曆日期的方法：陰曆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曆日期表達，如欲將陽曆日期換算成陰曆日期可以用以下兩種方法：其一是查《新編萬年曆》，如查1984年6月8日是陰曆幾日？ 翻開萬年曆6月10日是陰曆十一，則逆推6月8日是陰曆初九。其二可以利用公式推算陰曆日期：
設：公元年數－1977（或1901）＝4Q＋R
則：陰曆日期=14Q+10.6(R+1)+年內日期序數-29.5n
（注:式中Q、R、n均為自然數，R4）
例：1994年5月7日的陰曆日期為：
1994－1977＝17＝4×4＋1
故：Q＝4，R＝1 則：5月7日的陰曆日期為：
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，餘數27即是陰曆二十七日。
