java 实现 阳历转阴历

阴历(lunar calendar )不像阳历(solar calendar )那么有规律,只能按照天文观测中心发布的推测数据来推算。按照目前的推算只能推算到2050 年。

在代码实现上也有很多方法,一般都是以一个世纪的开始第一个正月初一开始推算,例如有的是以1900131 日(庚子年正月初一),有的是以200025 日(庚辰年正月初一),还有的是以任何一个已知的正月初一的日子开始推算。

大致的步骤是:

  •   按照阳历的日子,计算当日到已知的正月初一的总天数
  •   然后按照已知推测规律,算出,当前阴历的年份、月份、日。
  •   将得到年份分别模1012 ;获得天干地支
  •   然后再整理输出

先来看一下,先预先拿到的推测规律,都是以多位16 进制来表示的。我见过两种规律。

 

第一种 ,由五位十六进制数字表示:

0xX XXXX

  • 中间三位,转成十二位二进制,就是当年正常的12 个月,从左到右依次表示一月到12 月,0 表示小月,即29 天,1 表示大月,即30 天。
  • 最后一位表示当年的闰月,1 表示闰一月,2 表示闰2……a 表示闰10 月,b 表示闰11 月,c 表示闰12
  • 第一位表示当年的闰月,是闰大月还是小月,1 表示闰大月,即30 天,0 表示闰小月,即29 天。

例如:19000x04bd8

表示当年闰八月,闰小月,即29 天。中间三位转换后为010010011011 ,表示二月、五月、八月、九月、十一月、十二月为大月(30 天);其他未小月(29 天)。

第二种 ,由三位或五位十六进制数字表示:

  • 如果为三位数字,则表示当年只有12 个月,无闰月,将其转换为十二位二进制,从左到右依次表示一月到十二月的大小月,1 表示大月,即30 天,0 表示小月,即29 天。
  • 如果为五位,则表有闰月,后四位,为转换为二进制,其前三位肯定都是0 ,后13 为才有效。表示当年的十三个月的大小月,1 表示大月(30 天),0 表示小月(29 天)。其第一位十六进制数字表示,当年闰的哪个月份1 表示闰一月,2 表示闰2……a 表示闰10 月,b 表示闰11 月,c 表示闰12

例如:1900  0x8096d

第一个十六进制为8 ,表示闰八月。

后四位六进制转成二进制为,0000100101101011 。除去前三位,我们来看一下
