// 1-4: 表示当年有无闰年，有的话，为闰月的月份，没有的话，为0。
// 5-16：为除了闰月外的正常月份是大月还是小月，1为30天，0为29天。
// 注意：从1月到12月对应的是第16位到第5位。
// 17-20： 表示闰月是大月还是小月，仅当存在闰月的情况下有意义。
// 举例：
// 1980年的数据是： 0x095b0
// 二进制：0000 1001 0101 1011 0000
// 表示1980年没有闰月，从1月到12月的天数依次为：30、29、29、30 、29、30、29、30、 30、29、30、30。
// 1982年的数据是：0x0a974
// 0000 1010 0 1001 0111 0100
// 表示1982年的4月为闰月，即有第二个4月，且是闰小月。
// 从1月到13月的天数依次为：30、29、30、29、 29(闰月)、 30、29、29、30、 29、30、30、30。
