盡管通過很多渠道可以輕松獲取公歷轉農歷，但是對excel迷們還是很期待用excel來實現公歷轉農歷。

　　設想一下，IT部落窩會員們的信息都是以陽歷注冊的，我們也可以使用下面即將介紹的方法實現excel公歷轉農歷。

excel公歷轉農歷方法一：使用text函數

　　A列是公歷日期，我們在B1單元格輸入公式：=TEXT(A1,"[$-130000]yyyy年m月"&IF(LEN(--TEXT(A1,"[$-130000]dd"))=1,"初","")&"d")，下拉完成公歷轉農歷。

excel公歷轉農歷方法二：使用text+MID函數

　　A列仍然是公歷，B1輸入公式：=MID("甲乙丙丁戊己庚辛壬癸",MOD(TEXT(A1,"[$-130000]e")-4,10)+1,1)&MID("子丑寅卯辰巳午未申酉戌亥",MOD(TEXT(A1,"[$-130000]e")-4,12)+1,1)&"年"&TEXT(A1,"[$-130000][DBNum1]m月d日"即可。

excel公歷轉農歷方法三：使用text+MID+ CHOOSE+ YEAR函數

　　A1為公歷，B1輸入：=CHOOSE(MOD(YEAR(A1)-1900,10)+1,"庚","辛","壬","癸","甲","乙","丙","丁","戊","己")&CHOOSE(MOD(YEAR(A1)-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")<>

excel公歷轉農歷方法四：使用自定義函數

　　上面介紹的excel公歷轉農歷都是使用excel內置函數完成的，有一個弊端就是公式太長，如果使用自定義函數，在公式欄就可以簡化輸入。

　　如下圖所示，我們在B2輸入公式：=nongli(A2)，即可。C列農歷簡稱中C2公式是：=RIGHT(B2,LEN(B2)-8)。

　　關于自定義函數的使用方法請參考：excel自定義函數添加和使用方法

　　下面是此自定義函數相關的代碼：
