首先打开EXCEL创建两个单元格标题，其次设置现在时间可以直接使用excel的=NOW（）函数，在A2单元格输入=NOW（），输入完=NOW（）函数，直接回车就可以看到当前时间：
，第三显示星期几需要用到IF函数TODAY函数WEEKDAY函数，在星期下的B2单元格输入公式：
=IF(WEEKDAY(TODAY())=2,"星期一",IF(WEEKDAY(TODAY())=3,"星期二",IF(WEEKDAY(TODAY())=4,"星期三",IF(WEEKDAY(TODAY())=5,"星期四",IF(WEEKDAY(TODAY())=6,"星期五",IF(WEEKDAY(TODAY())=7,"星期六","星期日"))))))，点击回车就可以看到星期几了。
