* 农历数据表
*
* 农历分大小月，大月30天，小月29天，但一年中哪个月为大月，哪个月为小月，是无规律的。
* 农历每十年有4个闰年，但哪一年为闰年也是不确定的。
* 而闰月中，哪个闰月为大月，哪个为小月也是不确定的。
*
* 下面共20行，每行10个数据。每个数据代表一年，从阳历1900.1.31日起，为第一个数据年的开始，即阳历1900.1.31＝农历0.1.1。
* 200个数据可推200年的农历，因此目前最大只能推算到2100年
*
* 对于每一个数据项，5个十六进制数 = 20个二进制位
* 前4位，即0在这一年是闰年时才有意义，它代表这年闰月的大小月，为1则闰大月，为0则闰小月。
* 中间12位，即4bd，每位代表一个月，为1则为大月，为0则为小月。
* 最后4位，即8，代表这一年的闰月月份，为0则不闰。首4位要与末4位搭配使用。
