公立轉農歷

㈠ 公歷農歷轉換

回歷、公歷、農歷的換算
（128 × 365＋31）日÷ 128年＝ 365．2421875日/年
可見共置閏精度遠高於現代的公歷。
2．換算中一日誤差之訂正
《歷法叢談》以回歷1387年為例，求算合公歷之年月日。
解1：1387 × 0．970224＋621．5774＝1967．278088年
0．278088年 × 365．2422日＝101．569日公歷累計日數為101．57日可視為4月11日或4月12日。究竟是哪一日，當依兩歷在公歷4月11日或12日間所具有同一的星期序數以訂正。
依回歷歲首星期序數計算公式：
[（138－1）×131＋164] ÷30＝6057，餘20
6057÷7＝865，余 2
故回歷1387年元旦為星期2。（表）

按公歷自1583年元旦（星期六）至1967年4月11日，共歷：
1967－1583＝384年，在這384年中依格列高利歷四年一閏，百年不閏，四百年加一閏日的規則共歷93個閏日，又1967年元旦後一日起至4月11日又需加 100日，則
（384 × 365＋93＋100＋6）÷ 7＝140359＋7＝2001，余 2餘2即星期2，故回歷1387年元旦在公歷1967年4月11日。
因公歷計算星期日數採用數據較多，計算時難免有所遺漏，現引人公歷日期與星期推算表阿），供參考。
應用此表查找公元1967年4月11日星期序數步驟如下：
先在本表年份表前二位數字欄目中，查到19二字所在的位置；
再在年份表後二位數字欄目中查到67二字所在位置，自19二字處平行右移，67二字處垂直下移，二者在英文大寫字母欄目中相交於字母G處；
再自月份表欄目中查到4月，自4月所在位置平行左移，查到G在4月欄目所在位置；
自日期欄目查到11日所在位置，自此位置平行右移，使與4月份欄目G在星期表相交處知為星期二，結果與回歷計算所得相同。故知回歷 1387年元旦確為公歷1967年4月11日，而不是12日。
在換算中所得公歷日數常多於31日，甚至常在200—300日或更多，需要將此數化為該年的月日時，可用下列兩表。

三 公歷換算為回歷

將回歷換算為公歷的算式移項，整理，即可得到公歷換算為國歷的算式
（公歷紀年一621．5691）÷0．9702＝回歷年月日（儒略歷）……………………………………………（5）
（公歷紀年一621．5774）÷0．970224＝回歷年月日（格氏歷）…………………………………………（6）
無論回歷換算為公歷或相反，大體都有一日之差，以星期序數訂正時，回歷換算為公歷，以回歷的星期序數為准；相反，以公歷的星期序數為准。

四 國歷或公歷換算為中國農歷

1．回歷換算為農歷
僅管中國農歷各年在年內月數日數都不是一個相對的穩定值，給回歷與公歷換算為農歷上帶來較多的困難，但仍然可以換算。中國農歷為陰陽合歷，在月份上與回歷同屬太陰歷，惟回歷每月以見新月為一月之始，其日約遲於農歷合朔（初一日）1—2日乃至3日，因此只要查清二者在月份上關系，便可將回歷換算為中國農歷。馬以愚先生稱：「回教紀年及齋戒之月，均依太陰歷。中國昔用夏正（即農歷），有閏之年，年為十三月。故齋戒之月，遇閏則連退。如今歲齋戒值夏正之九月，歲逢閏，改歲當以八月為齋。」[8]故若求得積年及所歷大陰歷的月數，即可依農歷十九年而有七個閏月的規律，將農歷換算為回歷，其日當有l——2日之差。
計算舉例：已知西域魯穆馬依澤公於宋太祖建隆二年（961）應召人華編修《應天歷》，並將伊斯蘭天文傳人中國，他的事跡已收人《中國伊斯蘭網路全書》[9]與《中國回族大詞典》[10]等，被列為伊斯蘭與中國回族之大事。據《懷寧馬氏宗譜》記載，依澤公應召人華時年已四十，生於回歷勒比阿立勿里月（拉比爾·奧沃勒月，即回歷三月）第二十日，故於宋真宗景德二年（1005）五月初十日。宋太祖乾德四年（966）八月十三日奉旨授世襲候爵兼司天監。求依澤公生於公歷與農歷的年月日。

希望能幫助你

都是網上搜的，沒有現成的函數，有大俠寫好的自定義函數，參考著用吧

㈣ 新歷轉農歷

農歷一九九四年六月廿六的是新歷1994.08.03， 新歷1994.06.26是一九九四年五月十八。身份證上應該是農歷，不過不確定，問問家人

㈤ 有農歷和公歷相互轉換的函數嗎

農歷轉公歷：(供參考，不一定正確，閏年無法轉換)

B2=LOOKUP(--SUBSTITUTE(SUBSTITUTE(A2,-30,-28),-29,-27),--TEXT((LEFT(A2,5)&"1/1")+ROW($1:$400),"[$-130000]yyyy/m/d"),(LEFT(A2,5)&"1/1")+ROW($1:$400))+(--RIGHT(A2,2)>28)*2

驗算：C2="農歷"&TEXT(B2,"[$-130000]m月d日")
