這是一個國曆與農曆互相轉的Unit. 其中年份皆用民國年份, 請自行轉換 (西元年-1911 = 民國年).
***************************************************************************
*國農曆對映表之說明 : *
***************************************************************************
* 前二數字 = 閏月月份, 如果為 13 則沒有閏月 *
* 第三至第六數字 = 12 個月之大小月之2進位碼->10進位 *
* 例如: *
* 101010101010 = 2730 *
* 1 : 代表大月(30天) 0 : 代表小月(29天) ==> 1月大2月小3月大..... *
* 第七位數字為閏月天數 *
* 0 : 沒有閏月之天數 *
* 1 : 閏月為小月(29天) *
* 2 : 閏月為大月(30天) *
* 最後2位數字代表陽曆之1月1日與陰曆之1月1日相差天數 *
***************************************************************************
這對映表只有民國一年至民國一百年, 如不敷您的使用請按照上述之方式自行增加. 這個程式沒有判斷您所輸入之年,月,日是否正確, 請自行判斷. 如果轉換出來之農曆的月份是閏月則傳給您的值是***負數***
如果農曆要轉換國曆如果是閏月請輸入***負數*** 此版本為FreeWare Version : 0.1
您可以自行修改, 但最好可以將修改過之程式Mail一份給我.
如果您要用於商業用途, 請mail給我告知您的用途及原因. 作者 : 彭宏傑

這是一個國曆與農曆互相轉的Unit. 其中年份皆用民國年份, 請自行轉換 (西元年-1911 = 民國年).
***************************************************************************
*國農曆對映表之說明 : *
***************************************************************************
* 前二數字 = 閏月月份, 如果為 13 則沒有閏月 *
* 第三至第六數字 = 12 個月之大小月之2進位碼->10進位 *
* 例如: *
* 101010101010 = 2730 *
* 1 : 代表大月(30天) 0 : 代表小月(29天) ==> 1月大2月小3月大..... *
* 第七位數字為閏月天數 *
* 0 : 沒有閏月之天數 *
* 1 : 閏月為小月(29天) *
* 2 : 閏月為大月(30天) *
* 最後2位數字代表陽曆之1月1日與陰曆之1月1日相差天數 *
***************************************************************************
這對映表只有民國一年至民國一百年, 如不敷您的使用請按照上述之方式自行增加. 這個程式沒有判斷您所輸入之年,月,日是否正確, 請自行判斷. 如果轉換出來之農曆的月份是閏月則傳給您的值是***負數***
如果農曆要轉換國曆如果是閏月請輸入***負數*** 此版本為FreeWare Version : 0.1
您可以自行修改, 但最好可以將修改過之程式Mail一份給我.
如果您要用於商業用途, 請mail給我告知您的用途及原因. 作者 : 彭宏傑
