正确的解释是:
二进制形式
xxxx xxxx xxxx xxxx xxxx
20-17 16-12 12-9 8-5 4-1
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。
举个例子:
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。
