The modulo - 1o check digit , therefore , is the smallest number , which , when added to the result of step 4 , produces a multiple of 1o the following example calculates the check digit number for 489 1234 56789 设定一个能用10除尽，其值并大于第四步之总和的最小数值，并以数值减第四步总和所得之差，即为检核码(

By doing this , we are adding too much . hence , this extra day will not be added every hundred years , and it will be added again every four hundred years . for example , we have february 29 in the years 1988 , 1992 , 1996 , 2000 , 2400 , 2800 , etc . , but there will be no february 29 in the years 1997 , 1998 , 1999 and 1800 , 1900 , 2100 , 2200 , etc . this is called the 心思细密的读者会注意到，四年一闰即每年平均有365 . 25日，比一年的真实日数多了0 . 0078日，误差虽小，但数百年累积下来便不得了，所以历法规定，可以被100除尽的年份不置闰例如1700 1800 1900 ，但可以被400除尽的年份则保持置闰例如2000 2400 2800 ，因此，每400年便少了3个闰年，即平均一年少0 . 0075日，每年误差为0 . 0003日，或每3000年误差不多于一天。
