算法如下：

基姆拉尔森计算公式

W= (d+2*m+3*(m+1)/5+y+y/4-y/100+y/400) mod 7



在公式中d表示日期中的日数，m表示月份数，y表示年数。



注意：在公式中有个与其他公式不同的地方：



把一月和二月看成是上一年的十三月和十四月，例：如果是2004-1-10则换算成：2003-13-10来代入公式计算。-Algorithm is as follows:基姆拉尔森formula W = (d+2* m+3* (m+1)/5+ y+ y/4-y/100+ y/400) mod 7 in the formula d said the date the number of days, m said the number of months, y said that the number of years. Note: In the formula and other formulas have a different place: the January and February as the previous year Shisan Yue and Shi Siyue, example: if it is then converted into 2004-1-10: 2003-- 13-10 to represent into the formula.
